In the case of a plant so well known as is the typical form of P. 
triangularis, it seems hardly worth while to cite the very numerous 
specimens examined. As to range, specimens have been seen from 
Clark Co., Nevada; San Diego, Riverside, San Bernardino, Los 
Angeles, Santa Barbara, Kern, San Luis Obispo, Inyo, Monterey, 
Santa Cruz, Santa Clara, Mariposa, Alameda, Tuolumne, Calaveras, 
Amador, Marin, Sonoma, Yuba, Butte, Mendocino, Plumas, Te- 
hama and Humboldt Counties, California; Coos, Douglas, Lane, 
Linn, Marion and Multnomah Counties, Oregon; Klickitat, Pierce, 
Clallam and Island Counties, Washington; Vancouver Island, B. C.: 
and the northern part of Lower California. In specimens from 
Spring Valley, San Diego Co., Cal., (Feb.-May, 1900, Laura F. Kim- 
ball, N) and from Panamint Mts., Inyo Co., Cal. (Coville & Funston, 
610, N) the lamina is merely glandular beneath with no evidence of 
poisoning. Leiberg 3508 from near Sinartville, Yuba Co. (N), and 
part of the material under Mrs. R. M. Austin’s no. 977 from 
Quincy, Plumas Co. (N) represent white-powdered forms. 
All but one of the specimens seen from north of California, most of 
those from the northern and more inland portions and some from the 
southern part of that state, have the red glands mentioned above.
