In 1903 I described a Cuban species in the Proceedings of the 

 Biological Society of Washington, naming ilH. Sanbornii. At that 

 time I was unable to obtain satisfactory material oiH. eustachya, 

 and judged that the specimens described by Reichenbach were 

 different from mine. 



H. eustachya is readily distinguished from H. odontopetala by 

 its shorter spur and different labellum. In Cuba both species are 

 frequently found growing together on forested slopes, H. eusta- 

 chya blooming later than H. odontopetala in Pinar del Rio Pro- 

 vince. 



H. troyana, Fawcett &; Rendle, is a closely allied species from 

 Jamaica. 



In my herbarium there are several flowers taken from num- 

 bers 511 b and 2880 of the collections made by Sintenis (cf. origi- 

 nal description above). These flowers closely resemble the types 

 of H. Sanbornii and H. troyana.
