This account of P. bicornuta is based on an examination of 62 separate specimens, 

 and on the analysis of flowers from specimens of 29 different gatherings. 



The nearest ally of the species is P. elephantoides. The diagnosis is as follows: 



corolla throat contorted, beak deeply 2-fid P. bicornuta ; 



corolla throat not contorted, beak very long, entire at apex P. elephantoides. 



There are two distinct forms of the species — that from Garhwal and the . Pan jab 

 Himalaya with elongated looser racemes, with a longer corolla tube and with smaller 

 calyx teeth ; and that from the Trans-Indus district, which has more condensed racemes, 

 a shorter corolla tube, larger calyx teeth and a more densely leafy stem. But the 

 peculiarly contorted corolla throat which characterises this species and makes its 

 confusion with any other Indian species impossible is the same in both districts, so that 

 the forms are not separable even as varieties. Extreme conditions of the more Eastern 



form (Duthie 237!) from Rudughera in Garhwal have very lax racemes and closely 

 resemble P. megalantha, which species, however, is without the contortion of the corolla 

 throat and has hirsute anterior filaments. The Trans-Indus form, on the other hand, 

 repeats the habit and foliage of P. elephantoides.
