ORCHIDACE^ 



H.guadala- spur clavate, equalling the ovary: processes nearly a line long; 



jarana appendages at the base of the column very thick and verrucose. 



Guadalajara, in wet bottoms ; August. (276.) — Flowers greenish 

 yellow. With this in the Cambridge set is a small specimen with 

 fewer and smaller flowers and narrower acuminate leaves, which 

 belongs to some other species." Wats. loc. cit. 



All other specimens of Palmer no. 276 which have been ex- 

 amined are of the small species mentioned by Watson, and 

 appear to be related to H. subauriculata. Kranzlin reduces both 

 this and H. jaliscana to H. clypeata, apparently without hav- 

 ing seen the types. 



Habenaria guadalcijarana is a very distinct species. The type 

 specimen in the Gray Herbarium is about 2.6 dm. tall, with 

 rigid, ovate-lanceolate, appressed leaves. The spurs are distinctly 

 clavate, slightly exceeding 1 cm. in length. I have only seen 

 three collections of this species, four plants in all, which are \in- 

 douhtedly H. guadalqjarana. (Plate 76.)
