lected it at Willoughby, Vermont in July, 1913^. She has since found it in the 
vicinity of Round Mountain Lake, Franklin County, Maine,^^ and at Quechee 
Gulf, Hartland, Vermont. The two locaHties noted above represent the only 
known North American stations outside New England. In Europe D. 
gymno stoma philum has a fairly wide distribution but is everywhere rare. It 
seems to be confined to calcareous regions. 
9. Taxilejeunea EROSiFOLiA Steph. Species Hepat 5: 487. 1914. "Hab. 
America ieptenfnonalis. Florida. Cuba." 
A specimen of this species is in the Underwood Herbarium, now in the pos- 
session of the New York Botanical Garden. It was collected by J. Donnel 
Smith in Florida, no more definite locality being indicated on the label. In the 
writer's opinion this specimen clearly represents T obtusangula (Spruce) Evans, 
a species rediscovered in Florida by S. Rapp in 1913.^'^ Most of the perianths 
present are old and battered, so that it is difficult to demonstrate their true 
features, but at least one of them shows the depressed and beakless mouth char 
acteristic of Spruce's species. In all probability Stephani's description of T, 
erosifolia was drawn largely from the Underwood material, and it therefore 
seems safe to regard the species as a synonym of T. obtusangula. 
10. Ptychocoleus heterophyllus Evans, Am. Jour. Bot. 5: 144./. 5. 1918. 
Collected in January, 1920, at Sandy Bay, Nicaragua, on the bark of trees 
and on decaying stumps, by K. Hamilton (Nos. 224, 225); specimens received 
from Dr. P. O. Schallert. 
The present species was based in part on specimens from Florida, collected 
by S. Rapp, and in part on specimens from Honduras, collected by P. Wilson. 
These specimens were wholly without female inflorescences, so that their reference 
to the genus Ptychocoleus rather than to Brachiolejeunea had to be provisional. 
The new material from Nicaragua bears female inflorescences without subfloral 
innovations and thus proves beyond a question that the species is a true Ptycho- 
coleus. 
The female branches are more or less elongated and the leaves show a gradual 
increase in size as the perianth is approached. The bracts are in two to five 
pairs. The innermost bracts (Figs. 12 and 13) are complicate-bilobed about 
one fourth, with a rounded and wingless keel, which is straight or slightly arcuate. 
The lobe is broadly ovate, measuring about 1.2 x 0.9 mm., and tapers distinctly 
to a broad rounded or obtuse apex; the lobule is ovate-oblong, measuring about 
I X 0.5-0.6 mm. and less distinctly tapering. Both lobe and lobule are entire 
or nearly so. The bracteole, (Fig. 14), which is entirely free from the bracts, is 
oblong, measuring about i x 0.9 mm. and shows a broad rounded apex and entire 
margin, with little or no Midication of basal auricles. Although the lobules of
