longer and more tapering sepals, a lip destitute of tubercles or 
 callosities or lobes on either the upper or lower part, all of which 
characters occur in the European &. /at#folia. So decided is the 
difference upon close inspection that I have no hesitation in fol- 
lowing Reichenbach and adopting Hoffman’s name, &. viridi- 
flora, notwithstanding the fact that the specific name is not well 
chosen to indicate the color of the flowers. 
Three stations are now known for this plant. In addition to 
those near Syracuse and at Buffalo New York, another has 
recently been found at Toronto, Canada. 
Microstylis—Nuttall’s section of Malaxis known under. this 
name, as has been shown by Prof. Greene, is antedated by Ra- 
finesque’s name, Achroanthes, and our Northern North Ameri- 
can forms become: 
A. MONOPHYLLA (L.), Greene, Pitt. ii., 183 (1891). 
Ophrys monophylla, L. Sp. Pl. 947 (175 3).

| Habenaria ciliaris and H. blzephariglottis——So far as I can see, 
the specific difference between these two forms can hardly be 
maintained. According to Michaux, who seems to have been the 
first to mention the white colored plant, it is merely a white va- 
riety of HZ. ciliaris, and this judgment appears correct. Dr. Asa 
Gray, in the Annals of the Lyceum of Natural History of New — 
York, ili., 231, says that the two species “grow in similar situations 
and frequently in company, and are not readily distinguished ex- 
cept by the color of the flowers. But, as Prof. Hooker justly re- 
marks in H. ciliaris, the lip is more thickly fringed, and the upper — 
petals are likewise fringed; whereas in 7. b/ephariglottis these are — 
quite naked.” Numerous specimens of the two species in the — 
Columbia College Herbarium show that the lip varies in both | 
species from loosely to thickly fringed, and is the same identically — 
in shape. If it were the fact that in the one the petals are fringed © 
and in the other not, that might serve to distinguish them, but it — 
is now well known that the petal of d/ephariglottis are commonly _ 
as much fringed as in ciliaris. It is vay in | var.
