Pimpinella L. is one of the largest genus of the subfamily Apioideae (Family: Apiaceae)
having 200 species, distributed in Asia, Europe, and Africa (Mabberly 2008). Only
a few species of the genus are reported from South America and one occurs in
North America (Pimenov & Leonov 1993). In India, the genus is most speciose by
having about 20 species (Mukherjee & Constance 1993).
De Candole (1827) divided
the genus Pimpinella into three sections: Tragoselinum, characterized by its glabrous fruits and perennial roots; Tragium,
with hairy fruits, perennial (rarely biennial) roots and pinnate to bipinnate
radical leaves with ovate segments; and Anisum,
which included species with down-covered annual fruits. Bentham & Hooker (1867) reported 65–70
species of the genus Pimpinella and classified
it into six sections according to the habitat of the plant, leaf & fruit
morphology, and petal colour. Pimpinella can
be distinguished from other genera by mainly perennial herbs, cordate-ovoid or
oblong-ovoid, slightly laterally compressed fruits constricted at their
commissures, each with five filiform ribs (Pu & Watson 2005).
During floristic survey of Satara
District of Maharashtra State, some specimens belonging to the genus Pimpinella were collected from Ajinkyatara
Fort. Initially, we identified the
unknown Pimpinella species as P. wallichiana Gandhi.
But after critical examination of specimens through perusal of
literature (Hooker 1879; Rao & Hemadri 1976) and
consultation of type and other specimen from BSI and SUK the specimens were
identified as Pimpinella katrajensis Rolla Rao & Hemadri.
Mukherjee & Constance (1993) subsumed P. katrajensis into P. wallichiana
without any reason while Almeida (1998) treated it as a variety of P. wallichiana based on leaf characters; however, both
species are very distinct (Table 1).
Thus, in this communication we have provided morphological description,
images, and distinguishing characters of P. katrajensis
for correct identification and distribution note in Maharashtra State as
also help resolve the name on the PlantList.
Pimpinella katrajensis Rolla Rao & Hemadri
Indian Forester 102(4): 232–234; 1976. (Image 1)
Perennial erect aromatic herbs; root fusiform, about
10cm long; stem terete striate, pubescent to glabrous,
leaves pinnately trifoliate, petiole 12–15 cm long, sheathing at base, puberulous, ovate-orbiculate, cordate to truncate, acute at
apex, margins coarsely toothed and cartilaginous, lower surface minutely
pubescent, sparsely pubescent on upper surface; uppermost leaves smaller. Inflorescences terminal compound umbels,
large, tall, bisexual, puberulous, primary rays c.
5cm long, secondary rays 6–7 in number, 1–2.5 cm, long, puberulous,
ebracteate. Flowers 6–15 per umbel, ebracteolate, unequal pedicellate, pedicels pubescent. Calyx teeth not distinguished. Corolla white, hairy outside, petals 5,
broadly ovate, with notch at tip, stamens 5, anthers 0.3–0.4 mm long. Stylopodium
distinct, conical shaped, styles very short.
Fruit laterally compressed, ovoid, 2.2–3 mm long, pubescent to tomentose.
Carpophore bifid.
Flowering & fruiting: September–December.
Habitat: Grows on rocky crevices on slopes at
high altitude.
Distribution note: Pimpinella
katrajensis is endemic to Maharashtra and only
reported from two localities, Katraj Ghat near Pune and Pachgani in Satara District, however it is also distributed at Ajinkyatara, Vasota, Ambedare and Pateshwar in Satara District.
