ORCHIDACE^ 



lobed, the lateral lobes reduced to auricles, middle lobe 7 mm. 

 long, about equally broad, suborbicular, apiculate, margin entire. 

 Between the lateral lobes and uniting them in such a manner as 

 to form a deep pocket in front of the column, there is a complex 

 carunculated crest which passes into three short prominent keels 

 at the base of the middle lobe and follows the course of the three 

 middle nerves, otherwise the disc of the labellum is naked. Col- 

 umn 5 mm. long to the base of the upper sepal, produced into a 

 fleshy foot about 3 mm. long, broadly bialate at the summit, the 

 wings 2.5 mm. long by 2 mm. wide; rostellum produced into an 

 awl-shaped deflexed process. Anther two-celled, attached to the 

 fleshy, triangular termination of the back of the column. Pollen 

 masses two, in dried material readily disintegrating into tetrads; 

 viscid disc elliptical. (Plate 111.)

 Savannah. A very beautiful terrestrial. No pseudobulbs; Britton, Broad-

My studies of Otostylis brachystalix led to a close examination 

 of the plant that has passed unchallenged as Cyrtopodium oris- 

 tatum Lindl. among Trinidad species. It is a true Cyrtopodium 

 characterized by small flowers that are usually borne in simple 

 racemes. When this species is compared closely with the type of 

 Cyrtopodium cristatum collected in British Guiana by Schom- 

 burgk it becomes very apparent that the Trinidad species is quite 

 distinct from it. As far as I have been able to ascertain it is a 

 new species and for it I propose the name Cyrtopodium Broad- 

 wayi.
