The original S. nepalense is distinctly known by its somewhat 

 lax inflorescence, large coloured bracts, and spurs as long as the 

 ovary, or longer. The two others have very short spurs. Of 

 these, 8. ciliatimi has a thin inflorescence like that of >S'. nepalense 

 itself ; S. Wightianum has a very dense inflorescence ; both are 

 much dwarfer than S. nepalense. The specimens under my exami- 

 nation may be arranged thus v — 



251. S. Nepalense. D. Bon, Prodr. Fl. Nep. 26; Wight, Ic. 929. (S. 

 Perrottetianum, Ach. Rich, Ann. Sc. ser. 2. xv. 76 ; Wight, Ic. 1716. 

 — S. albiflorum, A. Rich. 1. c; Wight, Ic. 1717' S. pallidum, A. 

 Rich. 1. c). 



Sikkira, 7000-12,000 feet, stout, like Gymnadenia, J. D. H. (259) ;

S. Ferrottetianum is merely a gigantic state of the species, while 



;S^. pallidum is its starved form ; not, however, the most so, for the 



old specimens sent from Nepal by "Wallich among his earliest 



collections are still more attenuated. 



252. S. Wightianum, Lindl. Gen. Sf Sp. Orch. p. 340; Wight, Ic. 1718. 

 Nilgherries, Perrottet (191 & 850 in hb. Mus. Par.), Wight; Khasija, 



Lobb. 

 A much dwarfer plant than the preceding, with two broad radical 

 leaves suddenly changing to about two great inflated herbaceous 

 sheaths, and an extremely dense blunt spike. Plowers "rubri 

 aut coccinei" according to Perrottet, pink according to Wight, 

 and smaller than in >S'. nepalense. 



253. S. eihatum, Lindl. 1. c. 



Sikkim, 7000-12,000 feet, J.D.H. (259); Bootan, grassy sward above 

 Tongsa, 10,000 feet, Griffith. 



The very short spurs of this are so different from the long 

 attenuated ones of S. nepalense, that I think it must be distinct. 

 Moreover it is a smaller plant with 2-3 spreading herbaceous 

 distant sheaths, but little inflated. In the original specimen the 

 bracts are large and herbaceous, in those from Bootan much 

 smaller and deflexed, the plant varying like S. nepalense in that 

 respect. 



DiPLOMEEis, D. Don. 



254. D. pulchella. Id. 



Khasija, Griffith, 2000-4000 feet, /. D. H. ^ T. T. (256). 

 Plowers pale straw-colour or nearly white, variable in size. 

 Spur green.
