is usually straight or nearly so and bears a narrow wing with few or 
no teeth. The cuticle in the Greenland plants is strikingly verruculose.

(Acrolejeunea) atroviridis Spruce, Jour. Linn. Soc, Bot. 30: 335. 
pi. 20, f. 5-10. 1894. 
In a recent discussion of the West Indian species of Ptychocoleus 
{Acrolejeunea)^ the writer calls attention to the fact that certain char- 
acters of the present species are aberrant to that genus and that its 
systematic position is perhaps elsewhere. A study of the type ma- 
terial in the British Museum shows that this view is correct and that 
the plant is really a member of the genus Lopholejeunea, as above 
noted. It should be mentioned, however, that Spruce himself at first 
referred the species to Lopholejeunea, transferring it to Acrolejeunea in 
his published paper. The perianth in L. atroviridis is four-keeled and 
the keels bear narrow denticulate wings. The perichaetial bracts are 
likewise sparingly toothed. In general habit the plant resembles L. 
Muelleriana but the lobules are more like those of L. Sagraeana. The 
species grows on rocks, and the type locality is Richmond Valley, 
St. Vincent, where Elliott found it in February, 1892 {No. 219). He 
afterwards collected it at two stations on Dominica, Picard Valley 
{No. 442) and Castle Brace River {No. 1661). Specimens from 
both these stations also, determined by Stephani, are preserved in the 
British Museum. No other localities for the plant have been reported. 
8. Ceratolejeunea INTEGRIFOLIA Evans, Bull. Toney Club 
38:213. pi. 9, f. 13-19. 1911, 
Collected several times by S. Rapp, near Sa^'ford, Florida, the 
earliest date being April 12, 1903. Known also from three stations 
on the island of New Providence. Perianths not yet discovered. 
9. Brachioleieunea BAHAMENSIS Evans, Bull. Torrey Club 
35: 383. pi. 28, f. 1-14. 1908. 
Collected in November, 1901, on Old Rhodes Key, Florida, by 
J. K. Small and G. V. Nash, {No. 464, in part). The species is also 
known from various islands in the Bahamian Archipelago and from 
Cuba. 
10. Caudalejeunea Lehmanniana (Gottsche) Evans, Bull. 
Torrey Club 34: 554. pi. 33, f. 1-12. 1908. 
Collected in October, 1906, in a hammock near Long Prairie, 
Florida, by J. K. Small and J. J. Carter {No. 2812). Widely dis- 
tributed in tropical America. 
Specimens of the three Lejeuneae just noted are preserved in the 
herbarium of the New York Botanical Garden. They increase the 
number of Lejeuneae known from Florida to twenty-seven.
