(133 ) 
above with a felt of dark red radicles below. Leaves some- 
what distant, irregularly spreading, up to 6 mm. long, lance- 
olate with costa scarcely or short excurrent and margins 
minutely serrulate. Lamellae up to about 24, the median 
from 5 to g cells high, terminating in 1 or sometimes 2 cells, 
transversely oblong in section, about twice wider than high 
and not or scarcely depressed. Blade of leaf-bearing lamellae 
on either side of costa of only two layers of cells thick with 
cell walls on back of leaf not thickened. Leaf-cells in blade 
between base of lamellae and margin of leaf mostly from 
.O12 by .016 mm. to .o16 by .o20 mm. (Plate 22.) 
These specimens have been compared with specimens of 
inconstans Hagen in litt., collected by C. Jensen at Lilleel- 
vedal, Norway, lately received from Harold Lindberg, fil., 
and are without doubt the same. ‘The species is peculiar in 
the broad terminal cell of the lamellae, often doubled, the thin 
cell walls on back of leaf, very small teeth of margin and 
short excurrent nerve.

Neckera pennata (L.) Hedw. Sheep Camp, Dyea Creek.

NVeckera pterantha C. M. & K. Dawson. Increvices of 
rock. Fruiting abundantly. Secondary stems scarcely 
branching. Paraphyllia abundant or almost wanting (693). 
Pterigynandrum filiforme Hedw. Sheep Camp, Dyea 
Creek. On trees (696). 
Pterigynandrum jfiliforme decipiens (Web. & Mohr.) 
Limpr. Lake Lindeman. Onrock. This variety is darker 
colored and grows in larger, looser tufts than the species 
with the tips of the stems and branches more curved (697).
