side with a dense tuft of yellow hairs, whence the specific name. 



The type is no, 7991, collected June 8, 1905, on hills west 

 of Yreka, Siskiyou county, California, growing on the banks of 

 a small stream. It is one of the P. glaber aggregates, but is 

 clearly distinct from that species, the type of which came from 

 the region lying east of the Rocky mountains known in those 

 days as "Upper Louisiana." Pursh describes it as "filamento 

 sterili nudo clavato apice retuso, calycis foliolis subrotundis acu- 

 minatis." 



A plant similar to ours was collected by Mr. or Mrs. Brand- 

 egee at Klamathon, some miles northeast of Yreka. Careful 

 field study of our so-called P. glaber will no doubt show that we 

 have several distinct species in California, and that true glaber 

 does not occur here.

 No. 7771, collected April 26, about a mile inside of Kern 

 canyon, Kern county, the plants growing in clumps and very 

 showy with the profusion of large buff flowers. It is common 

 in the Tehachapi mountains on steep northerly slopes in damp 

 places.

No. 7838, collected May 6, at Bakersfield, Kern county, 

 where it is not uncommon along irrigating ditches. Whether 

 this is really the same as the plant from Unalaska, the writer 

 has no means of determining, not having the original diagnosis 

 at hand, and Professor Greene in his paper in the Journal of 

 Botan}', January, 1895, does not point out the distinguishing 

 characters. This particular form is a rather stout plant with 

 rounded hollow stem, glabrous except in the extreme upper part 

 of the inflorescence, where it is both pubescent and glandular.
