ORCHIDACE^ 



lished in 1866, referred Wright's 1480 and 621 to Sauroglossum 

 monophyllum Griseb., citing Lindley's Cranichis monophyllay 

 based on Wright's Cuban specimens, as a synonym, but such a 

 procedure had nothing to justify it, as C. monophylla was a species 

 in good standing prior to the time when Lindley pubUshed his 

 paper on Wright's Cuban collection of orchids, and as Wright's 

 621 which Lindley confused with C. monophylla is a true Cra- 

 nichis. 



It would seem that the transference of Cranichis monophylla 

 Lindl. to Cyclopogon, made by Schlechter, resulted from a de- 

 pendence on the synonymy cited by Cogniaux, and that attempts 

 to identify Lindley's Venezuelan species were based on a study of 

 Wright's 1480 rather than on Linden's material from Venezuela. 



Cranichis tenuiflora Griseb, Cat. PL Cub. (1866) 268. 



Wright's specimens of 621 that I have examined are diphyl- 

 lous, one leaf being much larger than the other, somewhat ovate- 

 cordate in outline, with a petiole about 3 cm. long. The smaller 

 leaf is lanceolate, acuminate, acute and gives to the plant a very 

 distinctive appearance. When compared with Swartz's type of 

 Cranichis diphylla it becomes very apparent that the Cuban plants 

 are clearly related to it. Wright's 621 is the same as his 3292 

 which is the type number of Cranichis tenuiflora Griseb.
