Abstract: Impatiens violacea is a steno-endemic species in a valley in Pettimudi forest adjacent to Eravikulam
National Park, Kerala, India. Taxonomic treatment, morphology, vertical
distribution, ecology, phenology, ethnobotany, threats, and conservation status
of the species are provided. Impatiens violaceae
is a threatened species under the ‘Vulnerable’ category with substantial
anthropogenic stress. The present study on endemic species in Pettimudi forest revealed 13 endemic species of the
southern Western Ghats reside at area of (1.87 km2) in a U-shaped
valley within the forest of Pettimudi, of which three
species, namely, Impatiens violacea, I. johnii, and Cnemaspis
anamudiensis were exclusively endemic to this
valley whereas I. panduranganii to the Pettimudi forest. The findings suggest that the
u-shaped valley in Pettimudi forest is an area of
endemism (AoE) and a ‘hot speck’ within the Western
Ghats, recognised as one of the global hotspots.
Based on the study result, the authors recommend the u-shaped valley in Pettimudi forest be attached to the Eravikulam
National Park territory to conserve the endemic species.
Keywords: Anthropogenic

INTRODUCTION
The Western Ghats-Sri
Lanka is one of the hottest hotspots with 4,780 plant species having 2,180
endemic species, which is 17.5% of the global endemic plant community (Myers et
al. 2000). In India, the Western Ghats extends from southern Gujarat and run
approximately 1,600 km and end up in Kanyakumari in the southernmost tip of India
(Singh et al. 2019). The southern Western Ghats lies between south Canara of
Karnataka and Kanyakumari of Tamil Nadu with a 30–40 km discontinuation called
Palghat Gap at Kerala (Nair 1991; Augustine 2018). One of the unique features
of the southern Western Ghats is the presence of tropical montane cloud
forests, which occurs at 1,400–2,400 m, popularly known as shola forests and
this high-elevation cloud forest habitat hosts a high level of endemism (Robin
& Nandhini 2012; Singh et al. 2019).
Endemism is the term
for a species’ exclusive existence in a designated geographic area. Since the
endemism idea is purely phenomenological, various taxa may be endemic to the
same region as a result of disparate historical processes (Fattorini
2017). Areas where the distributions of at least two taxa overlap are called
areas of endemism (AoE) (Quijano-Abril et al.
2006). Endemic areas or areas of endemism are the foundation of comparative biogeography, and identifying areas of endemism is essential
for biogeographical regionalisation (Parenti & Ebach 2009). Local endemism and hot specks are observed
within the Western Ghats-Sri Lanka biodiversity hotspot (Cherian 1996; Bossuyt et al. 2004). Hot specks are small niches within
the biodiversity hotspots with a high concentration of diverse species
including endemic ones. Identification of hot specks or small local hot spots
is requisite for extensive conservation management (Trivedi & Bharchula 2023; Harris et al. 2005; Murray-Smith et al.
2009) and endemic species are most convenient to identify biodiversity hotspots
(Myers et al. 2000; Mittermeier et al. 2005; Orme et al. 2005). For the
identification of the area of endemism, the study based on endemic flora and
fauna is very helpful in locating such hot specks for regional conservation
management.
The genus Impatiens of
the family Balsaminaceae is a highly diversified
genus with more than 900 species distributed in tropical Africa, Madagascar,
southern India, Sri Lanka, the eastern Himalaya, and southeastern Asia (Bhaskar
2012). The most striking features of this genus are the high degree of endemism
and regional endemism. The genus Impatiens in southern India and Sri
Lanka has c. 95% of endemism (Grey-Wilson 1980). In India, more than 210
species of Impatiens have been reported and from southern
India 106 species and 13 varieties, of which 103 species and 13 varieties were
endemic to the Western Ghats (Hareesh et al. 2015).
From parts of the Western Ghats in Kerala, 88 taxa of Impatiens were
reported within which 73 taxa were endemic to this region (Bhaskar 2012; Sasidharan 2013). Many new species are still being
described in this region (Narayanan 2013). Kumar & Sequeira
(2001) first described Impatiens violacea as
an endemic epiphytic parrot-billed Impatiens from the shola
forest of Pettimudi near Eravikulam
National Park, Kerala.
In the Pettimudi forest, only very few studies on flora and fauna
have taken place (Ramasubbu et al. 2011; Prabhukumar et al. 2017; Cyriac
et al. 2018; Prasad et al. 2018). In the present study, the aim is to extend
the knowledge of morphology, ecology, and spatial distribution including the
vertical distribution and threats of a vascular epiphyte Impatiens violacea. The paper also focused on the habitats that
have received less conservation and research attention by identifying endemic
species of flora and fauna in Pettimudi forest and
thus gaining insight into the degree of endemism in that area and the need for
conservation.
MATERIALS &
METHODS
Study Area
The study was
conducted in a u-shaped valley at Pettimudi forest
which lies in the north 10.1750N, 76.9950E, south 10.1630N,
76.9910E, west 10.1720N, 76.9840E and east
10.1710N, 76.9980E (Image 1). The area comes under the
reserve forest located adjacent to the south-west periphery of Eravikulam National Park, Idukki, Kerala. This area comes
under the Munnar Territorial Forest Division of the Kerala Forest Department.
This valley faces towards the west and the elevation of the valley varies
1,450–1,900 m. To examine the distribution of I. violaceae,
the type locality and surrounding areas including the Pettimudi
forest and the Eravikulam National Park were
investigated. The vegetation is composed of a tropical montane cloud forest
surrounded by steep mountains with a single narrow corridor (Image 1) and a few
small and large perennial streams flowing west towards the Edamalayar
Dam. Therefore, the tribal people refer to this large patch of shola forest as
“Valiyathoducholai.” (Valiya
– large, thodu – creek, cholai
– shola). Pettimudi forest receives heavy rainfall
during the south-west (June/July) and retreating (October/November) monsoons, and has an annual rainfall average of 5,500 mm
making it one of the wettest places in Kerala with the ever-recorded highest
rainfall of 61.6 cm/day on 6 August 2020 (Achu
et al. 2021). The temperature varies 10–24 °C with the lowest
temperature from December to January and the highest in April and May. The
average humidity during the winter season is above 80%.
Sampling
Field studies were
conducted from August 2020 to November 2022. The study site location was noted
using the geographic positioning system (GPS) including exact altitude with
latitude and each tree (phorophyte) having I. violacea
species were selected. Each selected tree was divided up into five
vertical tree zones according to Johanson (1974) and Krömer & Gradstein (2016) (Figure 1). These zones were
categorized as the base (Z 1; from the ground to 2 m), trunk (Z 2; 2 m above
the ground to the first bifurcation), Zone 2 is subdivided into a humid lower
part of the trunk (Z 2a) and a dryer upper part (Z 2b). Inner canopy (Z 3; the
inner third of the branches in the crown), mid-canopy (Z 4; the middle third
branches of the crown) and (Z 5; the outer third of the branches of the crown
(Figure 1). The epiphytes were classified into one of three ecological groups (Acebey et al. 2003; Krömer &
Kessler 2006; Krömer et al. 2007): habitat
generalists (occurring in three or more zones) and habitat specialists
(occurring only in one or two zones or three continuous ones); the latter were
further subdivided into canopy epiphytes (occurring (> 90% in Zones Z3–5)
and trunk epiphytes (> 90% in understory and Zones Z1–2). Within each tree
zone, the occurrence of I. violacea was
observed along with abiotic factors such as relative humidity, temperature,
light, and wind using Lutron LM 800A. Binoculars were used for the observation
of I. violacea anchoring in the canopy
branches and if necessary climbing the host trees were also done using single
and double rope techniques (Lowman & Moffett 1993). Detailed morphological
studies were done using a Leica EZ4W stereomicroscope. Herbarium specimens were
prepared as per the standard method (Jain & Rao 1976). Voucher specimens
were deposited at St. Albert’s College Herbarium (SAC). For the distribution of
endemic species of plants and animals in the study area we conducted a field
survey along with the details available from literature and other zoological
records.

Vernacular name: Neelakondrapoo (Muthuvan tribal
language) (Neela – Blue, Kondra
– prawn shaped, poo – flower)
Phenology: Flowering
period is limited to three months (August–October), coinciding with the two
main monsoon periods. The fleshy stems effectively close down, lose their
leaves, and shrink in diameter throughout the dry summer months. When the rainy
season finally arrives, the stems swell to their previous size. The stems end
up looking like a string of beads as a result of this. All of the Indian
epiphytic species belonging to Impatiens including I. parasitica, I. jerdonia,
and I. viridiflora have this type of
moniliform growth pattern. This trait may aid the epiphytic species in
surviving dry, droughty conditions and can be considered an ecological
adaptation for epiphytism.
Ethno-medical uses: Impatiens violacea have been used as medicine for the
treatment of paralysis. The entire plant is ground into the paste and applied
to the affected part. This tribal medical practice is recorded in the oral
tradition of Muthuvan tribes.

Distribution and
ecology of I. violacea
During the present
study, I. violacea was recorded and
collected only from the Pettimudi forest valley (1,836
m; 10.1670N, 76.9970E) in the Idukki district of Kerala,
India (Image 1B). The habitat of I. violacea was fragmented into two by a long gravel
forest road from Pettimudi towards Edamalakkudy, a tribal Gram panchayat consisting of 25
settlements inhabited by Muthuvan tribes, one of the
isolated indigenous tribes of the Western Ghats. This epiphyte can be regarded
as a true epiphyte because it remains detached from the forest floor and the
phorophyte’s vasculature during its whole existence. This species was found
distributed on the trees with closed canopy located on both sides of this
forest road at an altitude of 1,800–1,900 m. Even though the valley is very
closely connected to Eravikulam National Park (ENP),
the species was observed only at a u-shaped valley in Pettimudi
forest indicating the ineffectiveness of seed dispersal along with heavy and
few numbers of seeds compared (Image 2) to the minute and numerous seeds of
successful epiphytes such as orchids and ferns (Grey 1980). I. violacea possesses explosive ballistic
dispersal with a high likelihood of reaching an unfavorable place for the seed
to germinate, which is a crucial stage in the life cycle of plants. Another
element influencing the limited dispersion may be the valley surrounded by
steep mountains highly humid conditions and very low or null wind inflow inside
a closed canopy.
The plant species
were vertically distributed on phorophytes in three tree zones from Z3 to Z5
and were more prevalent in mid-canopy (Zones 3 and 4). This epiphytic species
can be considered an ecological group, habitat generalists (Occurring in three
or more zones).
Abiotic factors such
as temperature, relative humidity, light intensity, and wind at each vertical
zone of phorophytes having I. violacea were
observed. Microhabitats in the phorophyte reveal a model of vertical change
where abiotic factors such as temperature, and light availability increase with
the height of the phorophyte, while humidity simultaneously decreases with height
and wind velocity are null to calm. Another contrasting observation in the
habitat of I. violacea was the close
association with non-vascular epiphytes. All I. violacea individuals
were observed in moss-covered bark of phorophytes and none of them were
observed on bare bark.
The vertical
distribution pattern observed in this study can be associated with the
ecological adaptation of I. violacea.
This true epiphyte is vertically distributed from phorophyte (Z3–Z5), these
zones receive maximum light with low humidity. The distribution pattern of
abiotic factors such as temperature and humidity in our study was in accordance
with studies of (Walsh 1996; Freiberg 1997) where temperature increases from
the ground level to the canopy, while air humidity decreases. The most
important parameters determining epiphyte placement are humidity and
temperature (Benzing 2008). This drought-avoider
epiphyte has desiccation-prone foliage with a woody tuberous stem to withstand
canopy zones with maximum light along with low humidity and dry seasons.
This species found only on the moss and humus-covered bark of phorophytes
may be a result of the lack of specialized root systems that may anchor to the
phorophyte’s bare bark. According to numerous findings, epiphytic bryophytes
help vascular epiphytes establish themselves, survive and coexist (Van Leerdam et al. 1990; Tremblay et al. 1998; Zotz &
Vollrath 2003; Thomas & Jameson 2020). Especially in tree species with
smooth bark, bryophytes may improve seed anchoring and result in a more
dependable water supply during germination, but they may also lessen the
severity of drought in later ontogenetic phases. This impact is anticipated to
be a diminishing function of plant size (Zotz et al. 2001), which may be
attributed to the I. violaceae having a
variety of small- to large-sized plants. In montane forests, the constant
presence of humidity can be favourable for the
specialization of microhabitats of epiphytic plants (Gentry & Dodson 1987).
Threats and
Conservation status of I. violacea
The population is
estimated to be 87 individuals (mature – 60 and juvenile – 27) where all are
observed only from the type locality. Moreover, the type locality of this
species is in a landslide-prone area. A catastrophic landslide event occurred
at the windward slope of this valley mountain in August 2020 due to heavy
downpours (Achu et al. 2021). A
major anthropogenic threat observed was habitat fragmentation; a gravelled forest road fragmenting the habitat into two and
the government’s new proposed project to make this gravel road motorable from Pettimudi to Eddalipparakkudy
will severely affect the survival of this beautiful species in the
wild. Habitat fragmentation in plants can potentially impact a huge number
of progenies in the quantity of progeny produced, but also the genetic and
biological quality (Aguilar et al. 2019). It has been observed that this
threatened species is illegally harvested and traded in the national and
international markets. In general, the illegal plant trade threatens and
destroys numerous species, and important natural resources, and can cause
phytosanitary risks (Lavorgna & Sajeva 2021). The whole plant part used by Muthuvan tribals for ethnomedical
purposes also makes this plant reduce in number of individuals. All these
threats altogether make the remaining populations in this valley face in an
uncertain future. Being a steno-endemic species to Pettimudi
Valley, very restricted distribution in the upper montane cloud forest (shola
forest) with small population size in the wild and high risk of natural and
anthropogenic stress makes the species threatened and can be classified as
Vulnerable under criterion D2 (VU D2) under the IUCN Red List Categories and
Criteria.
Endemic species in Pettimudi forest
The single-patch
shola of Pettimudi forest is surrounded by steep
mountains harboured by endemic flora and fauna. In
the study, the u-shaped valley of Pettimudi forest
(1.87 km2) consists of 12 endemic plant species and one reptile
species. The type locality and distribution of three steno-endemic taxa were
located within an area of 0.023 km2 within this valley. This
includes a species of geckos (Cnemaspis
anamudiensis) and two species of
Impatiens (I. violacea & I. johnii) along with I. pandurangani
which is endemic to Pettimudi forest (Image 1) (Prabhukumar et al. 2017; Cyriac
et al. 2018). Barnes described Impatiens johnii
from Kallar Valley adjacent to Pettimudi
forest in 1931. The plant was believed to be extinct until it was rediscovered
by Biju & Kumar (1999) after 67 years from Pettimudi
forest. A recent study on the distribution pattern of I. johnii revealed that the plant is restricted only
to less than 5 km2 in Pettimudi Valley
(Prasad et al. 2018). A similar result was observed in our study, with the
population of I. johnii near I. violaecae.
A detailed list of
endemic species from Pettimudi forest is mentioned in
Table 1. Areas of endemism (AoE) are places where the
ranges of at least two taxa overlap (Quijano-Abril et al. 2006).
Therefore, the U-shaped valley in Pettimudi forest
with three steno endemic species can be considered as an area of endemism. Our
results on the distribution of endemic taxa in this valley indicate that there
are 13 endemic species here, making it a hotspot within the Western Ghats. A
study by Shajitha et al. (2016) confirmed that
southern Western Ghats species of Impatiens including I.
violacea have belonged to recent
lineages, so I. violacae can
be considered as steno-endemic taxa, evolved recently, constrained by steep
mountains of Pettimudi with no sufficient time to
expand its range. The tropical forests of the Western Ghats are considered
‘refugia’ harbouring highly diverse endemic taxa and
montane habitats, particularly acting as ‘species pumps’ (Johnson et al. 2022).
According to Kumar & Sequeira (1996), the
Western Ghats is a region of speciation of the genus Impatiens. This
assessment was consistent with our observations which favour
the presumption that this small valley in Pettimudi
forest is a cradle of speciation. The molecular phylogeny study of the
genus Impatiens indicates that southern Western Ghats species
of Impatiens were colonized from southeastern Asia by two
independent dispersal events, i.e., once by a southeastern Asian ancestor and
another time by an ancestor with African affinities. The phylogeny and
biogeography study of I. parasitica and I.
latifolia showed African affinities (Yuan
et al. 2004) and I. violacea and
I. johnii have a southeastern
Asian relationship (Sajitha et al. 2016).
In the case of
endemic reptile Cnemaspis anamudiensis of the genus Cnemaspis
Strauch, 1887 is one of the most species-rich genera of the family Gekkonidae which is distributed from Africa to southeastern
Asia (Sayyed et al. 2018). According to Kier et al. (2009), the endemic
richness of plants and vertebrates is correlated. The topography of the valley
surrounded by steep mountains was complex. A large mountain with topographic
complexity, isolation, and different microclimatic conditions promotes endemism
and biodiversity (Badgley et al. 2017; Noroozi et al. 2019).
Conclusion
In the current
investigation, it was found that I. violacea is
a threatened species that is currently Vulnerable. Due to its steno-endemic
status to Pettimudi forest, rare distribution at the
upper montane cloud forest (shola forest) along with its low wild
population size puts it in significant danger of near extinction in the wild in
the future due to multiple anthropogenic stresses. Our results
indicated that the u-shaped valley in Pettimudi
forest is an area of endemism and can be strongly considered a ‘hot speck’
where it is a hot spot within the southern Western Ghats hotspot and a cradle
of speciation. This study highlights our understanding of the endemic diversity
of the Pettimudi forest, which is essential for
understanding the biogeographic relationships among the recognised
areas of endemism (AoEs). Considering the relevance
of the Pettimudi forest’s unique endemic diversity,
public policies for the conservation of this region need to be generated. Also,
a proposal that recommends this u-shaped mountain valley in Pettimudi
forest to be attached to the Eravikulam National Park
territory. This research emphasizes the importance of comprehending the endemic
biodiversity of the Pettimudi forest to better grasp
the biogeographic connections between recognised AoE. Given the significance of the unique endemic biodiversity
in the Pettimudi forest, it is imperative to
formulate public policies for the conservation of this region. In addition, a
proposal suggesting the incorporation of the U-shaped Mountain valley in the Pettimudi forest into the territory of the Eravikulam National Park is recommended.
