cate, each with a long, squarrose, acuminate apex, with a short 
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. crinitum Sulk, but differing in the entire leaves 
and the long peristome, the inner not adhering to the outer 
Specimens not compared.

Plants light green, glossy ; stems creeping and rooting ; branches 
about 1 cm.; leaves imbricate, concave, with reflexed points; vein 
very short and indistinct; margins incurved, entire, forming a cu-

slightly decumbent. 
Plants sterile. Alliance not determined. 
Neckera Jamesoni Taylor. Sorata, 8000 ft., February, 1886 
(3169); Unduavi, 8000 ft., October, 1885 (3169a).

Porotrichum (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 
ong beak; annulus large, simple ; peristome double, teeth long, 
slender, endostome of slender papillose carinate segments, open 
along the keel; cilia none. 
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. 
1361-1363) from which ours differ in being much coarser, with less 
slender, not flagellate branches and shorter stouter pedicels,
