virens nigrescens Schimp.) A depressed, blackish variety 
growing on the margin of an alpine pond just below snow 
banks about 1000 ft. above Lake Lindeman (791). 
Oncophorus Wahlenbergi Brid. (Cynodontium Wahlen- 
bergit Hartm.) Common about Dawson on old stumps and 
logs, in fine tufts, up to 6 cm. high (530). 
Dicranella crispa (Ehrh.) Schimp. On damp sandy soil 
at mouth of Bonanza Creek (552). 
Dicranella varia (Hedw.) Schimp. Below Lake Lebarge 
on Thirty-mile River (551). 
Dicranella heteromalla (L..) Schimp. Sheep Camp, Dyea 
Creek (554). 
Dicranella subulata (Hedw.) Schimp. Growing on a thin 
layer of damp earth over rock at Lake Lindeman (553). 
These specimens have the upper leaves somewhat serrulate 
above, thus approaching curvata, but the capsule is scarcely 
elongated, erect and symmetrical enough to be that. 
Dicranum fulvellum (Dicks.) Smith.* On rock at Long 
Lake a few miles below Chilcoot Summit. The specimens 
are old and blackish with distinctly furrowed capsule. Leaf- 
cells not pitted and costa .o50 mm. wide at base (531). 
Dicranum falcatum Hedw. Sterile plants collected on 
rock at Lake Lindeman. The leaf-cells from apex one-half 
down are short and angular, often nearly square, the excur- 
rent costa of the upper leaves is very rough with teeth-like 
projections of the cells, width of costa at base .o80 mm. (532). 
Dicranum molle Wils. Collected at Lake Lindeman on 
damp, clayey soil subject to overflow. The specimens bear 
very immature capsules but show a distinct struma. The 
leaves are entire or nearly so and erect-spreading, with cell- 
walls thickened and pitted chiefly a little above the base, the 
upper cells elongated, often rectangular and 4 to 6 times 
longer than broad. Costa about .065 mm. wide at base, 
about + leaf base. This species has been previously collected 
outside of Europe in Alaska and Greenland (546).
