Allied to VW. crinitum Sull., but differing in the entire leaves 
and the long peristome, the inner not adhering to the outer

Porotricium (THAMNiuM) Borrvianum C. M. n. sp. Near Yun- 
gas, 4000 ft., 1885 (3174). 
Plants light yellowish-green, with a creeping rhizome; stems 
4-5 cm. long, naked below, about 2 cm., bipinnate ; branches flat- 
tened, frond-like, red; leaves compressed, elliptical-oblong, unequ 
at base, about I mm. long; vein dividing and disappearing below 
the broad sharply serrate apex; margins entire below; cells of me 
basal angles only slightly differentiated ; monoecious; antheridi

Allied to Porotrichum longirostrum (Hook.) Mitt. and possibly 
referable to this variable species, according to Mitten. Compared 
at Kew with specimens collected by Spruce (And. Quit. nos. “ 
1 361-1 363) from which ours differ in being much coarser, with less” 2 
slender, not flagellate branches and shorter stouter pedicels, :
