GREENMAN, — NEW ANGIOSPERMS FROM MEXICO, 1F 
no. 9632 (hb. Gr.), agree in all essential characters with the type of the 
above species, which was collected in the State of Oaxaca. The speci- 
. obtained in Puebla, however, represent a more advanced stage of 
evelopment, the plants being 3.5 dm. high, and the oldest flowers are 
reflexed, showing the immature 1.5 cm. long capsule.

With the exception of the last, all the above cited specimens have been 
_ regarded as identical with Hexalectris aphylla, Raf., but all the 
exican material thus far examined by the writer proves to be quite 
Hexalectris mexicana differs from A. aphylla, 
smaller flowers, less 
smaller and more 
distinct from that species. 
Raf., in its somewhat smaller average size, slightly 
conspicuously nerved parts of the perianth, shorter, 
deeply 3-lobed labellum. The labellum, moreover, in H. mexicana bears 
only 2 to 4 lamella and these are opposite the lateral sinuses while 
in H. aphylla the labellum is 5-(6-)lamellate from below the lateral 
sinuses, and the median fold is more or less continuous to the apex of 
the middle lobe.
