Bright green or yellowish, growing in depressed mats: stems 
appressed to the substratum, irregularly and often copiously 
branched, the branches widely spreading, similar to the stem; 
rhizoids variable in abundance, occurring singly or in small clus- 
ters: leaves distant to subimbricated, the lobe obliquely to widely 
spreading, ovate or semiovate with a rounded or very obtuse apex, 
averaging about 0.35 X0.2 mm. (but varying much in size), 
margin crenulate from projecting cells; lobule usually represented 
by an indistinct fold, connected with the lobe by a rounded keel, 
crenulate along the margin except near the base and with an indis- 
tinct apical tooth and sinus, hyaline papilla marginal but slightly 
displaced to inner surface; leaf cells convex, thin-walled throughout, 
averaging about 14 along the margin, 184 in the middle of the 
lobe, and 22u at the base: inflorescence autoicous: 2 inflorescence 
borne on a more or less elongated branch, innovating on one side, 
more rarely on both, the innovations often floriferous; bracts simi- 
lar to the leaves but a little larger, erect-spreading, the lobe 
0.45 X0.25 mm., the lobule a little shorter and narrower with a 
rounded apex, margin crenulate as in the leaves; perianth obovoid, 
0.45 mm. long, 0.3 mm. wide, sharply five-keeled to about the 
middle, the keels roughened from projecting cells, beak short and 
broad, often almost obsolete, basal stipe (formed after fertili- 
zation) sometimes very conspicuous: o inflorescence very variable 
in length and in the number and form of the bracts, the latter 
distant or subimbricated, erect or erect-spreading, in more typical 
cases subequally bilobed with a strongly arched keel and rounded 
divisions, the lobule a little shorter than the lobe; antheridia 
borne singly or in pairs: capsule about 0.2 mm. in diameter; spores 
greenish, minutely verruculose, about I4qu in short diameter; 
elaters about 3u in diameter. 
On bark of trees. Near Cayey, Evans (101). This species 
was originally described from specimens collected by Ramon de la 
Sagra at Havana, Cuba, and was afterwards found by Wright 
on the same island and distributed in his Hepaticae Cubenses. 
It is known also from St. John (Danish West Indies), Breutel
