Specimens Examined: 

 California: Mt. Shasta, Brovon No. 391 (type collection). Plants 

 15-30 cm. high, Leaflets narrowly oblong to linear, 2-3 cm. 

 long, 2-5 mm. wide. 



Mt. Eddy, Heller No. 12096. Plant 60 cm. high; leaflets 

 2-4 cm. long, 2-7 mm. wide. 



Water Canyon, Tehachapi Mts., Abrams & McGregor 

 No. 443; both narrow and broad-leafed forms on the 

 same sheet, the latter referred to schaffneri. The nar- 

 row-leafed forms match exactly some of the plants of 

 the type collection of brownii. 



Castella, Piper No. 6367; 



Butte Co., Mrs. R. M. Austin No. 1169; 



Greenhorn Mts., Siskyou Co., G. D. Butler No. 1346. 



The last three specimens have narrowly linear leaflets, 



2-6 cm. long and 1.5-2 mm. wide. The pods on Piper 



No. 6367 and Austin No. 1169 are broadest above the 



middle as also in Abrams & McGregor No. 443. This 



character may be of deeper significance, which only good 



complete material will disclose.

Klamath River, Applegate No. 2073; 



Friend, Wasco Co., C. E. Hill June 29, 1917.
