115 



This account of P. siphonantha is based on the examination of 117 separate speci- 

 mens of var. typica and of 13 separate specimens of var. brevituba. Analyses of 

 flowers from specimens of 71 different gatherings have been made. 



The corolla tube in this widely distributed species elon-ates gradually as it extent 

 from west to east; in Afghan specimens it is 18 mm. long, in Kashmir ones 30 mi ., in 

 Garhwal specimens 40 mm., in Nepalese 50 mm., in East Himalayan sometimes as much as 



somew 



besides the many gutln 



70 mm. long. The colour of the corolla 



where no field-note has been made, there are at Calcutta 35 in which the ooroUa _ 

 to be pink, 9 where it is noted as being rosepink, 4 where it is noted :..i being d< ,7, 

 purple; of one gathered at Yeum-tong Mr. Pantling has i.-.ted that tin bond

are deep purple, the lip and tube pale pink; Dungboo, one of Dr. Kim,* Lepeha 



tors, has carefully noted on 3 specimens obtained by him on the same day at Choon-gu 



gut hen i if. 



that one has a purple, another a pink, the third a white, corolla; of inotl 

 from Chumbi Valley the same collector notes the corolla as bein- pink outside and 

 white within. Jacquemont has noted of var. brevUuba " corolla albo-punctata- 

 recently Dr. Aitchison has noted of the same variety on a gathering from Si 

 Afghanistan, u flowers cherry-coloured with splashes of white

Of var. typica there are two distinct forms easily separated by habit and lea\ 



■ 



(a) "vera" = P. siphonantha Don. Prodr. ; dwarf densely tufted with short d< 



stems or stemless and with leaf segments nearly contiguous, the more usu d form in the 

 Central and Eastern Himalaya; and 



(/3) " Hookeriana-himalayca " = P. Ilookeriana Wall, and also = P. himalmica 

 Klotzsch; tall ascendiug~or erect (up to 35 cm. high) with leaf segments distant 



ommon 



and subalternate, the more usual form in the Western Himalaya though not 

 in the Eastern Himalaya also, more especially in Chumbi and in Phari. Western 

 dwarf forms have the corolla tube as short as it is in tall specimens from the 

 same districts ; Eastern tall forms have the long corolla tube characteristic of the 

 genuine dwarf Nepal and Sikkim plant. Finally, several gatherings from Lahul, Pangi 

 and Tehri have ovate leaf segments, and thus simulate var. brevituba ; from that varied 

 their longer corolla tube, more densely hirsute anterior filaments and more acutely- 

 toothed galea, throat alone distinguish them. 



Of var. brevituba there are also two distinct form 



(7) "Elephas" = P. Elephas Boiss., Diagn., but only partly of Bcnth., DC. Prodr. 

 and only partly of Boiss., Flor. Orient; with short stems and contiguous imbricate leaf 



gments, a Persian plant of which every character as given in the author's careful 

 description belongs to P. siphonantha except that he describes the filaments as glabr 



a point wherein he is in error as regards an Afghan plant that he has referred to 

 his own species; and 



(8) "punctata" = P. punctata Dene., also = P. labellata Boi«s. but not of Jacquem., 

 and = P. Hoolceriana Aitchison but not of Wall. ; tall erect with distant alternate leaf 

 segments, confined to the Panjab Himalaya and Trans-Indus districts. 



Of Indian species var. typica repeats the habit and foliage of the various forms of 

 P. longiflora, var. brevituba those of the different varieties of P. rhuwnthoide*.
