36 AMERICAN FERN JOURNAL 
Type in the U. 8. National Herbarium, no. 277737, 
collected at Helm Bay, Cleveland Peninsula, Alaska, 
in rich soil of forested mountain slope, July 19, 1901, 
by J. B. Flett (no. 1917). 
Besides a second frond of the type collection, the 
following additional specimens are in the National 
Herbarium: 
AuasKa: Sitka, C. V. Piper 4561; J. P. Anderson 2; 
H. C. Cowles 1076. Yes Bay, moist mountain slopes, 
M. W. Gorman 242, 1728. Head of Russell Fiord, 
Coville & Kearney 942. Point Gustavus, Glacier Bay, 
Coville & Kearney 724. Without special locality, W. 
H. Dall. 
The presence or absence of a proliferous bud upon 
the rachis seems here, as in the West Indian species, 
a character of first importance. The specimens above 
cited were mostly determined as P. Braunii, which 
likewise lacks this distinctive structure. Polystichwm 
Braunii occurs not infrequently in Alaska, sometimes 
in company with P. alaskense (e. g., Sitka, Bischoff, 
Evans 164; Yes Bay, Gorman 178) and is known to 
the writer from a single locality in British Columbia 
(Salmon River, Ymir District, W. C. Sandercock; Herb. 
Canadian Geological Survey, no. 89854).
