Stems 2-6 cm. high, 2-20 from stout branching rhizome, petioles 

 slightly dilated at base, pedicels 25-60 mm. rigid elongating in frnit, 

 calyx 10-12 mm. 5-toothed segments elliptic serrate tipper smallest, 

 corolla red tube 16 mm. distinctly widened at apes nearly glabrous 

 externally, beak 5 mm. segments with acute tips, capsule oblong oblique 

 shortly cuspidate nearly ^ exserted, seeds ovoid pale distinctly reticu- 

 lated. 



49. (24). P. SIPHONANTHA Don ; Hook. /. 



Var. typica; leaf segments lanceolate, corolla tube 4-5 times as long 

 as calyx, throat acutely bidentate. P. sipJwnantha Don, Prodr. Flop. 

 Nepal., 95 ; Wall., Cat. 417; Benth., DC. Prodr. x, 565. P. Hooheriana 

 Wall., Cat., 421 ; Benth., Scroph. Ind. 53, and DO. Prodr. x, 664. 

 -P. Jiimalaijca Klotzsoh, R.eis. Pr. Wald., Bot., 107, t. 58. 



In two very distinct forms : — a. " siplionantha vera ", with short 

 decumbent stems or stemless, leaf segments contiguous=P. siplionantha 

 Don ; Wall. ; Benth. 11. cc, the more usual form in Sikkim and Nepal, 

 comparatively unusual in Kamaon and not apparently occurring in 

 Kashmir or W. Tibet ; and p. " Hookeriaiia ", with long ascending or 

 erect stems, leaf segments distant subalternate = P. Hoolceriana Wall. ; 

 Benth. 11. cc. and = P. himalayca Klotzsoh 1. c, the form characteristic 

 of Kashmir and W. Tibet but occasionally reported from Sikkim also. 

 There are, however, forms intermediate in habit and as the floral struc- 

 ture is identical they cannot be looked upon as distinct varieties. 



Vae. brevituha; leaf segments ovate, corolla tube 2-3 times as long 

 as calyx, teeth of throat obtuse or almost absent. P. JElephas Boiss., 

 Diag., Ser. i; iv, 81, and Flor. orient., iv, 489 ; Benth., DC. Prodr. x, 

 565. P. punctata Done, Jacquom. Voy., Bot., Ill, t. 122; Benth., DC. 

 Prodr. X, 565. 



Also in two very distinct forms : — y. " Elephas ", with short stoma 

 and contiguous imbricate leaf-segments = P. JUlepJias Boiss. II. cc. as to 

 description but excluding " Griffith 1000 " which has apex of beak 

 entii-e and is, as Sir J. D. Hooker points out, P. rhinantlioides : — and 8. 

 '■^punctata " with tall rigid erect stems and distant alternate leaf-segments 

 = P. punctata Dene ; Benth. 11. cc, frequently distributed with spocimona 

 of form /3. as " P. Hoolceriana." Sjiecimens intermediate as to foliar 

 characters cei'tainly occur but " punctata" differs from Wall. Cat. 421 

 by its shorter tube, indistinct teeth, and very large lower lip the lateral 

 lobes of which embrace the throat and meet behind the galea ; these 

 characters though constant are not however of sjoeoific value. 



The forms of var. typica repeat the habit and foliage of the two 

 forms of P. longiflora, those of var. hrevituba repeat the habit and foliage 

 of the two varieties of P. rhinantlioides.
