"Differs from H. Sanbornii Ames in the smaller, narrower, 

 less membranous leaves, and the larger flowers with clavate, not 

 filiform, spur. H. Sanbornii is a larger, coarser-growing plant. 

 Very near H. eustachya Reichenb. f. in Ber. Deutsch. Bot. Ges. 

 iii. 274 (1885), from Porto Rico (Sintenis, no. 5116), which, 

 however, has the median sepal elliptical and obtusely acute. 

 We have not seen this number of H. eustachya, and possibly 

 H. Sanbornii may prove to be the same species." Fawcett & 

 Ren die, loc. cit. 



I have seen flowers of this species submitted for examination 

 by Dr. Rendle. They closely resemble flowers of H. eustachya 

 Reichb. f. as represented by Cuban material in my herbarium. 

 The spur is more decidedly inflated and the sepals and petals 

 larger than in the older species. The character of the leaves on 

 which the authors of J^^. troyana lay emphasis in differentiating 

 it from H. Sanbornii (which I refer to H. eustachya) is of ques- 

 tionable value, as the measurements they give apply in detail 

 to specimens oi H. Sanbornii. In the Gray Herbarium there 

 is a specimen from Orizaba, Mexico, collected by Botteri, 

 which is intermediate between H. troyana and H. Sanbornii, 

 and leads to the supposition that H. troyana is perhaps only
