Asplenium filix-joemina are generally found 
along streams. Equisetum telmateia is of in- 
frequent occurrence but attains large size, sterile 
plants being observed measuring from 1-1.5 
meters in height. Lysichiton camtschatcense, 
(Pl: VIi-). the only “representative wou ame 
Aracee in this region with its enormously long 
and broad leaves offers a marked contrast to 
the other types of vegetation and seems much 
out of place in a northern, coniferous forest. It 
grows typically in cool, moist, deeply shaded 
ravines. Liuzula campestris occurs occasion- 
ally along streams. Streptopus amplexicaults is 
common throughout the belt but is most frequent 
at the lower levels. Lzistera cordata, though 
somewhat rare, is found generally where the 
forest is very dense and where there is less of 
underbrush. Razoumojskya tsugensis, growing 
as a parasite on the branches and stems of the 
hemlock is most abundant in the low forest. 
Ranunculus bongardii, Tiarella trijoliata and 
Boykinia elata flourish on this forest floor where 
little or no direct sunlight falls. The latter two 
species are frequently found growing side by 
side, usually upon banks of streams.
