(i33) 



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 :.j, the median 

 from 5 to 9 cells high, terminating in i or sometimes 2 colls, 

 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 

 .012 by .016 mm. to .016 by .020 mm. (Plate 22.) 



These specimens have been compared with specimens of 

 inconstans Ilagen in litt., collected by C. Jensen at Lilleel- 

 vedal, Norway, lately received from Harold Lindberg, ill., 

 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. 



Collected at Lake Lindeman, in swampy places. May 26, 

 1898 (690).

(695)- 



Xcckera pennata (L.) Hechv. Sheep Camp, Dyea Creek.

Neckcra -ptcrantha C. M. & K. Dawson. In crevices of 

 rock. Fruiting abundantly. Secondary stems scarcely 

 branching. Paraphyllia abundant or almost wanting (693). 



Pterigynandrum filiforme Iledw. Sheep Camp, Dyea 

 Creek. On trees (696). 



Pterigynandrum pliformc decipiens (Web. k.v Mohr.) 

 Limpr. Lake Lindeman. On rock. 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).

 Creek, on trees. Skagway, on rock. All sterile (698).
