Abstract: An updated checklist of the
Rosaceae family occurring in the state of Arunachal Pradesh, northeastern
India, is presented here. Arunachal Pradesh, located in eastern Himalaya in the
northeastern part of India, is rich in biodiversity and endemism. To understand
the taxonomic diversity of Rosaceae in the state, a comprehensive taxonomic
study was conducted based on field collections, scrutiny of herbarium specimens
and published literature. The field surveys were carried out from 2019–2024 in
various localities of Arunachal Pradesh. A total 164 taxa (158 species,
8 varieties, and 1 subspecies) of Rosaceae have been recorded under 27
genera where the Rubus is found
as the most dominant one with 49 species. Four species are found as endemic to
the state. Rubus niveus var. micranthus (D.Don) H. Hara, Rubus
alpestris Blume, and Potentilla fulgens Wall. ex Sims have been
reported as new distributional records for the state of Arunachal Pradesh. The
findings of this study may provide the essential baseline data for
understanding the species richness, biogeographic patterns, and conservation
status of Rosaceae within the state.
Keywords: Conservation, diversity, endemic,
IUCN status, new distribution record, northeastern India, occurrence, synonyms.
Introduction
The family
Rosaceae is one of the most diverse and economically significant plant groups
in the order Rosales of core eudicotyledons. It is represented by around 104
genera and 5,250 accepted species (POWO 2025). The family has a worldwide
distribution, with the highest abundance in the Northern Hemisphere, particularly
in western North America and eastern Asia (Robertson 1974). The family is
characterized by deciduous or evergreen trees, shrubs, climbers, and mostly
perennial herbs (Kalkman 2004). Molecular phylogenetic studies have strongly
supported the monophyly of Rosaceae and its sister relationship to a clade
formed by the other eight families of the order Rosales (Zhang et al. 2011;
Angiosperm Phylogeny Group 2016). However, considerable progress has been made
in the evolutionary studies of Rosaceae due to the availability of DNA sequence
data (Wissemann & Campbell 2007). Potter et al. (2007) analysed six nuclear
and four chloroplast genes, identifying three major clades within Rosaceae,
viz., Rosoideae, Dryadoideae, and Spiraeoideae. The family is ecologically diverse
and economically valuable, with species used for ornamentals, timber, fruits,
and medicine. Many are recognized in traditional medicine, some for their
antibiotic properties (Ansari 2014), and widely used by ethnic groups to treat
various ailments (Khan & Shinwari 2016).
Arunachal
Pradesh, located in the northeastern part of India, is renowned for its rich
floristic diversity. The state encompasses a wide range of ecosystems, from
tropical and subtropical forests at lower altitudes to temperate and alpine
forests in the higher elevations. It is estimated that approximately 76.93% of
India’s plant families are found in Arunachal Pradesh (Halder et al. 2024).
Numerous floristic studies have been conducted in the state, significantly
contributing to the documentation of its plant diversity (Panigrahi & Naik
1961; Rao & Joseph 1965; Panigrahi & Joseph 1966; Chauhan et al. 1996;
Chowdhery et al. 1996; Ambrish 2013; Pal 2013; Bhuyan et al. 2015–16; Dash
& Singh 2017; Lidén & Adhikari 2019; Bhuyan & Pangu 2020; Taram et
al. 2020; Lidén & Bharali 2020). In addition to these floristic works,
several taxonomic studies have also been carried out by various researchers
(Gajurel et al. 2008; Srivastava & Choudhury 2008; Buragohain et al.
2014; Bhaumik 2017; Ranibala et al. 2018; Taram & Tag 2022). Many new
additions have been made to the flora of the state through these studies.
However, a comprehensive account of the plant families and genera, indicating
the current status of plant diversity, is still lacking. As the comprehensive
accounts of most of the plant families of the states are lacking, it is
difficult to estimate accurately the present status of occurrence of taxa in
any group.
The
Rosaceae family, one of the dominant and economically significant plant groups
in the state, is particularly underexplored. Although over 100 species have
been reported across various studies, a thorough examination of species
diversity within each genus is still needed. Such an assessment is essential
for a deeper understanding of the family’s diversity, which is crucial for the
conservation and management of these valuable taxa. In this context, the
present study is attempted to prepare a comprehensive checklist of the family
Rosaceae with respect to the state.
Materials & Methods
The
comprehensive inventory was compiled by reviewing the information available in
the taxonomic literature, herbarium specimens, and field surveys conducted by
the authors from 2019 to 2024 in various localities of Arunachal Pradesh.
Voucher specimens housed at the Arunachal Pradesh Regional Centre of the
Botanical Survey of India (ARUN), Eastern Regional Centre of the Botanical
Survey of India (ASSAM), Central National Herbarium of the Botanical Survey of
India (CAL), and the State Forest Research Institute, Itanagar (acronym: APFH),
were carefully examined. The databases ‘Plants of the World Online’(http://www.plantsoftheworldonline.org/)`
and ‘International Plant Name Index’ (http://www.ipni.org) was cross checked
for up-to-date nomenclature of the reviewed taxa. To comprehend the
conservation status of each taxon, IUCN red-list database of threatened species
(https://www.iucnredlist.org) was consulted. The species and infraspecific taxa
are arranged alphabetically along with synonyms, distribution, area of
occurrence in Arunachal Pradesh (AP), taxonomic notes and IUCN status.
Cultivated varieties and hybrids are not included in the present study for
taxonomic ambiguity.
RESULTS
We recorded
the occurrence of 164 taxa (158 species, 8 varieties, and 1 subspecies) of
Rosaceae from Arunachal Pradesh (Images 1–2). The genus Rubus L. is
represented by the maximum number of species (49 spp.), followed by Prunus
L. (15 spp.), Cotoneaster Medik. and Potentilla L. (11 spp.
each), and Spiraea L. (10 spp.), among others (Figure 1). Four species Rubus
ghanakantae, R. hapoliensis, R. ramachandrae, and Spiraea
subdioica were found to be endemic in the state. Rubus niveus var. micranthus,
R. alpestris, and Potentilla fulgens have been reported as new
distributional records for the state of Arunachal Pradesh. In the IUCN Red List
of Threatened Species, Prunus ceylanica is categorized as ‘Endangered’
(EN) while majority of the plant taxa were found as not evaluated (Figure 2).

DISCUSSION
The present
study revealed the occurrence of a total 158 species under 27 genera of
Rosaceae from the state of Arunachal Pradesh. However, Halder et al. (2024) in
their floristic revisionary work reported the occurrence of 137 species of
Rosaceae in the state. In this study, 21 species have been added to the list.
After critical scrutiny of the available literature, it is found that out of
158 species, Rubus
ghanakantae, Rubus hapoliensis, Rubus ramachandrae, and Spiraea subdioica are
found as endemic only to the state. The occurrence of the three taxa namely Rubus
niveus var. micranthus, Rubus alpestris, and Potentilla
fulgens have been reported as new distribution records for the state of
Arunachal Pradesh through the scrutiny of the herbarium specimens as the
available literature did not include these taxa. The richness of the species
diversity is directly influenced by the diversified climatic conditions and
availability of the preferred habitats. The temperate, subalpine, and alpine
forests prevailing throughout the state with normally cold and low temperature
provide the best conditions for the luxuriant growth and adaptation of the
species. The genus Rubus was reported to be the most dominant one with
more than 49 species representing almost 30% of the total species. The study of
Ansari (2014) also revealed the rich species diversity of the family
particularly the genus Rubus from Sikkim Himalaya. The rich taxonomic
diversity and distribution of the Rosaceae in the state with domination of the
genera like Potentilla, Fragaria, Rubus, Malus, and Prunus are
also reported in the earlier works (Panigrahi & Joseph 1966; Chauhan et al.
1996; Chowdhery et al. 1996).
In our study,
it is also found that botanical names used as accepted species name in the
earlier floristic works like Flora of Arunachal Pradesh (Chowdhery et al.
1996), Flora of Namdapha (Chauhan et al. 1996), Flora of Kurung Kumey District
(Dash & Singh 2017), and Flora of Lower Subansiri District (Pal 2013) are
found now as synonyms. The names such as Potentilla leuconota, Potentilla
lineata, Potentilla microphylla, Cotoneaster bacillaris, Sorbus cuspidata,
Docynia indica, Photinia cuspidata, Potentilla khasiana, Rubus kurzii, Rubus
indotibetanus, Rubus duthieanus, Rubus gigantiflorus, Pyrus expansa,
Spiraea arunachalensis, Sorbus corymbifera documented in Flora of
Arunachal Pradesh are now confirmed as synonyms.
CONCLUSION
The Himalayan
state of Arunachal Pradesh is one of the main region of the Indian species
diversity of the Rosaceae. The checklist prepared through this study will be
helpful to understand the species richness and biogeographic patterns of
Rosaceae in the state. The data of distribution and occurrence of the species
will facilitate the development of evidence-based plans and practical
conservation frameworks to protect the diversity of Rosaceae species in the
state. The findings of this study will also provide essential baseline
information to support conservation strategies and sustainable utilization of
resources. Moreover, the data accumulated through this study hold significant
potential to inform future research and development initiatives. However, the
complete taxonomic and ecological data to support proper identification and
understanding the population status of species would be more valuable for the
utilization and conservation of the species.
