ORCHIDACEiE 



H. crassi- *' 97. H. adenantha Nob. Subglandulosa : foliis elliptico-lance- 

 cornis olatis ; flor. viridibus glandulosis, sepalis internis lanceolatis, ap- 



pendice linear! angustissimo : labelli lobis linearibus glandulosis ; 

 calcare inflato ovarii longitudine." Rich. & Gal. loc. cit. 



Galeotti's type (no. 5051) is represented at Paris by a single 

 individual, a drawing by Richard of a plant, "no. 83, Juguila a 

 6500 ft.," and a drawing of a flower and details. The plant is a 

 very characteristic one oiH. crassicornis, the thick semi-oblong 

 apex of the spur ascending from a very slender basal portion, 

 giving the whole flower the appearance of an ichneumon fly, 

 the setaceous divisions of the perianth bearing a striking resem- 

 blance to the legs, the lateral sepals to the wings, the dorsal sepal 

 to the thorax and head, and the spur to the abdomen. (A.A.E.) 



H. crassicornis is very clearly distinguished from nearly re- 

 lated species by the minutely glandulose or denticulate petals 

 and lip. The ovary is also glandulose along the angles or wings. 

 In the drawing at Paris this denticulate character is clearly ex- 

 hibited, although in the original diagnosis of H. crassicornis no 

 reference to it is made by Lindley. 



In all the specimens of H. crassicornis I have examined this 

 denticulate or glandulose character is evident, but I did not look 

 for it in Lindley's specimen, — at least I made no note relating 

 to it. Lindley's sketch which accompanies the type exhibits a 

 perfectly smooth flower, as figure 2, plate 72 shows. In all other 

 respects this sketch suggests the flowers of H. adenantha Rich. 

 & Gal. Dr. Prain, in a communication received December 17, 

 1909, assures me "that the flowers of Habenaria crassicornis 

 are, in Lindley's original specimen, covered with little rough 

 points." This observation disposes of uncertainty. 



Dr. Kranzlin disregards H, adenantha in Orchidacearum 

 Genera et Species, and in his account of H. crassicornis makes
