 vein or veinless. Capsule brown, thick-walled, ovoid, about 2 

 mm. long, on a short seta ; peristome double, teeth long, slender, 

 yellow, endostome as long, carinate segments rarely open along 

 the keel; spores green, .021-.024 mm. 



Allied to M. crinituin Sull., but differing in the entire leaves 



and the long peristome, the inner not adhering to the outer 



Specimens not compared.

Neckera Janiesoni Taylor. Sorata, 8000 ft., February, 1886

PoROTRiCEiuM (Thamnium) Bolivianum 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, unequal 

 at base, about i mm. long ; vein dividing and disappearing below 

 the broad sharply serrate apex ; margins entire below ; cells of the 

 basal angles only slightly differentiated ; monoecious ; antheridial 

 buds on different branches from the archegonia; perichetial leaves 

 longer, outer squarrose, subulate, often veinless, inner erect-clasp- 

 ing, with a narrow vein ; seta red, flexuous, 10-15 mm. long; cap- 

 sule 2 mm., ovoid-cylindric, neck short; lid 2 mm. long, with a

Allied to PorotricJuim longirostniin (Hook.) Mitt, and possibly 

 referable to this variable species, according to Mitten. Compared 

 at Kew with specimens collected by Spruce (And. Quit. nos. 

 1361-1363) from which ours differ in being much coarser, with less 

 slender, not flagellate branches and shorter stouter pedicels,
