cate to broadly rounded at the apex, ecallose, 3-nerved, 
the lateral margins nearly entire to erose, 4.5—6 mm. long, 
2.8-3.8 mm. wide. Column slender, compressed, 8-4 
mm. long. Capsule ovoid, about 7 mm. long. 
This species differs from C. odontorhiza,which it super- 
ficially resembles, in the larger, broadly obovate, ecallose 
lip and in the decidedly longer and narrower sepals and 
petals. So far as we know, this is the only species of 
Corallorrhiza whose flowers possess an ecallose lip. 
This species is named in honor of Dr. L.O. Williams, 
an assiduous student of the orchids of Mexico.

Il. A NEw VARIETY OF HABENARIA BLEPHARIGLOT- 
TIS FROM THE CUMBERLAND PLATEAU 
In the course of a recent study of the Orchidaceae of 
the southeastern states, several specimens of Habenaria 
blephariglottis (Willd.) Hook. were observed which had 
flowers whose lip was entire or nearly so rather than long- 
or short-fringed (a characteristic of the species). At that 
time (Bot. Mus. Leafl. Harvard Univ. 8 (1940) 89) these 
plants were referred to H. blepharigilottis var. holopetala 
(Lindl.) A. Gray. It now seems best to consider H.ble- 
phariglottis and var. holopetala as identical, and to de- 
scribe as a new variety of H. blepharigiottis the plants 
with flowers possessing an entire lip.
