"^A'ESTERN UNIFOLIA, 33 



It htas never come to me from any corresj^oiulent residing or 

 collecting anywhere in the Sierra Nevada ; and I have sought 

 it vainly during hundreds of miles of travel in that region. 

 Mr. Watson's plant of the AVahsatch, and other localities 



eastward of the Coast Kange will probably be the one 

 which furnished the ''nearly black" berries of his specific 

 character, Avhich, unless it prove to be my f7. liliaccuin in 

 fruit, should be fJ- siellahim. Neither in the AVahsatch nor 

 in any other range of mountains in Utah or Nevada is there 

 any recurrence of the peculiar climatic conditions of the 

 Coast Eange of California. Copious winter rains, little or no 

 snow, scarcely a frost, the ground never frozen, — these are 

 the conditions under which this species tlirives ; and we 

 should as much expect the redwood, the laurel and the peculiar 

 herbaceous flora of the Californian coast to be found in the 

 cold and dry interior basin, as this plant. Nevertheless, in 

 one place well to the eastward of the Cascade Mountains, it 

 does occur. I refer to the lake region of the extreme northern 

 part of Idaho Territory. Here there seems to have been let 

 down, as from the Alaskan coasts, a considerable tract of 

 moist coast forest, into the midst the cold and dry interior. 

 At Lake Pend d'Oreille are repeated the dense swampy ever- 

 green woods of a far northwestern sea-coast district ; and 

 here, in the same rich soil, in deep shades of fir and arbor 

 vitre, one meets with plenty of C/. sessilifolium ; and here too, 

 outside of and above the e^ woods, on open ground and in 

 dry soil grows the uimiistakable U. steUainm. It is the only 

 ground upon which the eastern and the western species are 

 known to meet; and there the contrast between them is 

 striking enough, every way. 



U. STELLATUM (L.), Greene, Bull. Torr. Club, xv. 287. This 

 crosses the continent ; occuridng near Pacific shores not only 



northward in British Columbia and AYashington, but even in 

 southern California. Not far north of the borders of Los 

 Angeles County I observed and collected it last June. Thi 

 particularly interesting and unexjpected station for the species 



December 30, 1889.
