Stems scarcely more than two or three lines in length, quite simple, somewhat
tufted. Leaves b rig h t pale yellowish-green, fading in age to almost
white, broadly and obtusely ovate, with a short, abrupt acuminate point,
very concave, entire at the margin, the nerve strong, and reaching near-
ly to the p o in t; they are all closely imbricated, with their summits as
itwere connivent, and the whole stem thus taken with the leaves is more
or less o f an ovate-oblong figure. Fruitstalk about h a lf an inch in length.
Theca oblong, reddish, erecto-cernuous. Lid obliquely rostrate, nearly
h a lf as long as the theca. Calyplra dimidiate. Peristome of 16 pale
teeth, a good deal attenuated at their apex, ^irregularly transversely
striated, and often more or less united at their base.
