formal name. 
An extreme sun-form of the var. sitchense is the forma strictum) 
which has narrowly lanceolate pinnules with revolute margins. It 
closely resembles the European var. converum Newman, but may be 
distinguished from that variety by the lower pinnae, which in the — 
European form are modified like the upper ones, whereas in the form 
now under consideration they are but slightly contracted, and resemble 
the basal pinnae of the typical var. sitchense. 
oe ni ne Filiz-femina var. sitchense occurs from the Aleutian Islands 
to California,’ chiefly near the coast, also at low apy isang in the 
Mountains of British Columbia, and i in northern Idaho.
