sterile species of Dicranum in dense tufts, copiously fruiting. 
Compared with nos. 11, 13, 14, I 7, 18, 20 and 21 of the species 
listed by Mitten in his Musci Austro-Americani. Most closely 
related to P. gracienta Upe., but differing in its smaller size and 
shorter pedicel. : 
PHILONOTIS PAGIONIFOLIA C. M., n. sp. Yungas, 4000-6000 ft. 
1885 (3139). 
Plants forming dense, matted tufts, with little fruit; stems 
short, branches fasciculate, about 5 mm. long, slender and curved 
at apex; leaves erect-spreading or secund, narrowly lanceolate, 
acuminate from a clasping, slightly decurrent base; margins 
thickened or revolute with several rows of teeth from base to 
apex ; vein thick, excurrent into a toothed subulate apex; cells 
clear and square at base, all papillose on the upper surface. Dioe- 
cious; perigonium broad and clear at base, long-cuspidate at 
apex ; perichetium concave, hyaline at base, ecostate, also with a 
long serrate tip ; both sets of bracts much longer than the stem 
leaves, Pedicels 20-25 mm. long, bright glossy, orange-colored ; 
capsule 3 mm. long, oblique, strongly ribbed when dry ; lid mam- 
illate ; peristome double. 
Resembling P. gracilenta Hpe. (Lindig, New Granada) but the 
leaves are more blunt. Compared with Mandon’s no. 1676 from 
Sorata, Bolivia, named by Schimper Philonotis Boliviana, it differs 
in its slender and delicate branches, which are less fasciculate. 
Specimens at Kew are much confused in this troublesome group 
of species, but ours do not seem to agree with any of theirs. The 
- Nearest are those collected by Matthews at Casapi, Peru, in Herb. 
Hooker, named by Wilson and labelled “ No. 2313, Bartramia un- 
einata” (B. scabrida Schwaegr. Supp. f/: 57), but they differ in the 
leaves being non-cuspidate and in the large ecostate perichetium. 
BarTRAMIA (PLICATELLA) SCORPIOIDES C. Miiller. n. sp. Near 
Yungas, 4000 ft., 1885 (3138). 
Plants large, 5—6 cm. high, decumbent and matted with brown 
_ tomentumat base, yellowish-green, glossy; stems arcuate, branching 
by innovations 1-2 cm. long, or fasciculate; leaves secund, uncin- 
ate, acuminate, plicate; vein narrow, ending in the carinate serru- 
late apex, forming a sharp point; cells all papillose, the end walls 
thickened; dioecious ; the antheridia surrounded by broad orange- 
colored bracts, with serrate papillose tips; perichetial leaves broad, 
Clasping and hyaline, smooth and entire, vein narrow, excurrent 
_ Into a slender point; pedicels 10-15 mm. long, red, curved at tip; 
_ Capsules all eaten off or decayed. _ :
