Standley 16107, collected on a steep brushy and wooded 
slope, under alders, near Grinnell Lake, at 1,500 to 1,650 
meters elevation. The specimens of both collections 
are fertile and apparently grew under favorable condi- 
tions. Those constituting no. 17443 are unmistakably 
referable to the form called P. Jenningsi, and though 
only 45 em. high, and thus considerably smaller than the 
type specimen (from Rainier National Park, Washing- 
ton), agree closely with other Washington material pre- 
viously listed by the writer, differing only in their rela- 
tively longer basal pinnae. The specimens collected as 
no. 16107, however, are about 80 cm. high and, while 
agreeing with the foregoing material in most respects, 
closely approach P. Andersoni (of which three fronds 
from the original plant are at hand) in their narrower 
pinnae and more noticeably awned segments. A criti- 
cal comparison of Mr. Standley’s two collections shows 
no dependable differences between them, and a review 
of the whole series indicates a single species in which the 
leaf blade varies from narrowly lance-oblong to lance- 
elliptic, the basal pinnae varying from a length of one- 
third to nearly two-thirds that of the middle pinnae. 
It seems necessary, therefore, to regard P. Jenningsi® 
as a synonym of P. Andersoni Hopkins, described a few 
years earlier.’ 
NotHoLaAENA Parryi D. C. Eaton. In listing the 
westernmost stations for Cheilanthes Feei not long ago* 
the writer, as a result of too hasty examination, mis- 
identified small specimens of Notholaena Parryi from 
Mountain Spring, California (Schoenfeldt 3080), as C. 
Feei. The mistake was noticed in coming upon much 
better specimens collected at the same locality by Parish 
(no. 9028) in 1914. The close similarity of the two spe-
