slender, elongated stems and more entire leaves. Some of 

 the perichaetial leaves are only -1- mm. wide and up to 3^ 

 mm. long, without teeth, the margin being slightly sinuate 

 only toward apex. These specimens agree in inflores- 

 cence and in every other way with specimens from Green- 

 land, and labeled sphaguicola apparently in Schimper's own 

 handwriting. Some half dozen other specimens in the 

 " Garden " collection from Europe and labeled sphaguicola 

 are very different plants (647). 



Pohlia commutata Lindb. ( Wcbcra commutata Schimp.) 

 Lake Lindeman. On sandy bank by stream. This species 

 may usually be distinguished from our other Weberas, I be- 

 lieve, by the comparatively broad, short leaves, ovate rather 

 than lanceolate, mostly 1-4, excepting a few perichaetial, 

 the only other species approaching it in this respect being 

 cucullala, which is paroicous (645). 



Pohlia gracilis Lindb. ( Wcbcra gracilis De Not.) On 

 shaded, moist sand bank of the Klondike River just above 

 Dawson. The specimens are not fruiting but bear abundant 

 red bulbs in the axils of the leaves, often 4 or 5 on the same 

 stem. The bulbs measure about .260 by .375 mm. and are 

 readilv observed at some distance by the naked eye. They 

 are borne on a very short stalk that comes out from the stem 

 some little distance above the attachment of the leaf (646). 



Pohlia proligera Lindb. ( Weber a proligera (Lindb.) 

 Kindb.) Lake Lindeman in marshy place. A dioicous, very 

 pale-colored plant, with elongated, spindle-shaped, more or 

 less vermicular brood-bodies, clustered in the axils of the 

 leaves. These bodies are quite variable in size and shape. 

 They usually consist of several series of cells somewhat twisted 

 together but apparently always terminating in a single pointed 

 cell and measure about .020 by .200 mm., or even larger. 

 The median leaf-cells are about .120 by .008 to .010 mm.

 and he has indicated several new species, the descriptions of which, how- 

 ever, have been drawn up by the author.
