There is no specimen in Schimper’s Herbarium at Kew bear- 
ng this name, so no comparison was possible. These specimens 
of Dr. Rusby’s have the leaves strongly costate to the apex, the 
costa is papillose on the back, the margins are entire below, 
serrate and recurved above, papillose and undulate, the upper cells 
are small and round, but not opaque, the basal cells longer and 
brown. 
Holomitrium Bolivianum C. Muller, n. sp. Near Yungas, 4000 
ft. (3190). 
Plants in light yellowish tangled mats, mixed with hepatics; 
stems 3-4 cm. long, flexuous and matted, with light-colored 
tomentum; leaves 3-5 mm. long, linear lanceolate, twisted and 
curled when dry, costate to apex, serrate and papillose above as 
well as undulate, entire with revolute margins below; cells round 
and small, lower ones hyaline. Plants sterile. 
This species was compared with H. flexuosum Mitt, at Kew, 
but it differs from No. 21 Spruce from Andes Quitenses in the 
leaves, nor does it agree with any other species from this region 
at Kew. It should be compared with H. longifoliinn Hpe. 
Dicranella angustifolia Mitt. Near Yungas, 4000 ft. (3112). 
Dicranella nanocarpa C. Muller, n. sp. Near Yungas, 4000 
ft. (3139 pp). 
Stems 3-5 mm. high, simple or branching, leaves erect or 
slightly secund when dry, uppermost often 2 mm. long, linear- 
subulate, margin entire, vein excurrent with a few indistinct teeth 
at apex; perichetial leaves broader and clasping at base. Dioeci¬ 
ous. Pedicels 5-8 mm. long, twisted above, bright orange; cap¬ 
sule erect, ovoid, less than .5 mm. long, with a longer straight beak 
on the lid than the theca, which becomes broad and hemispherical 
when empty; mouth with a dark border, peristome red, teeth fuga¬ 
cious ; cells of the walls oblong or hexagonal in regular rows. 
Only six plants found mixed with a specimen of Philonotis , No. 
3139; the alliance was not determined.

Plants stout and large, much discolored at base, glossy and 
yellow at the tips of the branches; stems 10-15 cm. long, decum¬ 
bent, branching by short innovations, tomentose in the axils of 
the leaves, often slender and interruptedly foliate; leaves longest 
at the tips of the branches, often 15 mm. in length and 1 mm. 
broad at base, to a concave apex with involute margins, entire 
below, serrate, becoming spinose along the excurrent vein ; basal
