Parnassia wightiana Wall. ex Wight & Arn. (Celastraceae) is a small alpine herb rarely seen in Uttarakhand.
Petals are characteristically fringed at base.
Photographed near Munsyari in Pithoragarh district of Uttarakhand at about 3500m altitude.
Another upload (in eFI) of this species from Nilgiris TN lack characteristic petals- efi thread .
Please help me in identifying the small herb. Commonly seen in wet places. the plant height is not more than 10 cm. Leaf: 2.5 cm across
Date: 24 Oct 2012
Place: Western Catchment, Nilgiris, TN
Alt.: 2300 m asl Seems to be Parnassia sp. Most probably Parnassia wightiana Wight & Arn. There are 2 species of Parnassia in Nilgiri hills. The petals are clear in the photographs and the height of scape is not measurable. Hence I cannot be definite of which species this plant. They are differentiated by Gamble in Flora of Presidency of Madras as follows: 1a. Scapes 6 – 12 in. high; leaves broadly ovate, cordate, 1 – 1.5 in. long; petals obovate, conspicuously fimbriate on the margins; staminodes 3 – 5-lobed, the lobes cylindric-clavate- P. wightiana 1b. Scapes 3 – 6 in. high; leaves orbicular, cordate, .5 – .75 in. long; petals obovate. not or slightly fimbriate on the margins; staminodes clavate, entire or more or less 3- or even 5-lobed- P. mysorensis You may check your live plants with these distinctions and come to a conclusion. Also check: http://delta-intkey.com/angio/images/fig021.jpg Leaf veins clearly indicates towards Parnassia wightiana Wall. ex Wight & Arn. References:
