PIPER FLORA OF THE STATE OF WASHINGTON. 333 



3. Rubus nivaHs Dougl.; Hook. Fl. Bor. Am. 1: 181. 1833. 



Type locauty: "On the high snowy ridges of the Rocky Mountains." Collected by 

 Douglas. 



Range: Washington, Oregon, and Idaho. 



Specimens examined: Upper Nisqually Valley, Allen 78; Mashel Mountain, Piper 710; 

 Silverton, Bouck 57a; Alma, Piper 1995; Olympic Mountains, Piper in 1880. 



Zonal distribution: Canadian. 



This species is abundant in deep forests near the base of Iklount Rainier. In such places, 

 however, it never blooms. Fertile plants must be sought either in recent burns or on 

 rocky outcroppings. The flowers are dull purplish in color. 



4. Rubus macropetalus Dougl.; Hook. Fl. Bor. Am. 1: 178. 1833. Dewberry. 

 Type locality: "In the valley of the Columbia." Collected by Douglas.

 1889; Roslyn, Whited 408. 



Zonal distribution: Humid Transition. 



This species is very close to R. ursinus Cham. & Schlecht. of California, but it seems 

 distinct. It never has unifoliolate leaves, which are so commonly produced in the latter. 

 The plant referred by Cooper to R. trivialis Michx. is probably R. macropetalus, but we have 

 been unable to find the specimen.

Two forms of this species occur, one with claret-colored or nearly black fruit, the other 

 with yellow fruit, the latter being the better flavored. The former may be distinguished 

 even in flower by the purple color of its twigs.
