Family Caprifoliaceae. 



Viburnum pauciforum Pylaie. Dawson and Miles Canon 

 (Williams) ; Five-finger Rapids (Tarleton). 



Linnaea Americana Forbes. Walker Gulch (Williams) ; 

 Five-finger Rapids (Tarleton). This North American plant 

 appears to differ constantly from the European L. borealis in 

 its funnelform, not campanulate corolla. 



Family Valerianaceae. 

 Valeriana bracteosa Britton, sp. nov. 



Similar to V. sylvatica and V. utiginosa, about 4 dm. 

 high, slightly pubescent at the nodes, otherwise glabrous. 

 Rootstock slender, horizontal; lower and basal leaves oval, 

 entire, petioled ; upper leaves about 3 pairs, sessile, with 3 

 lanceolate acuminate few-toothed segments, or those of the 

 uppermost pair entire : cyme open, its branches filiform ; 

 bracts very narrowly linear, black, much longer than the 

 fruit : calyx-lobes united near the base into a black cup, 

 loosely plumose : corolla 5-6 mm. long, its tube about equal- 

 ling the throat and limb. 



Type collected by R. S. Williams at Dawson, July 14, 



1899; also collected by Tarleton above Fort Selkirk, July 



12, 1899, no. 101a and 101b. 



Family Campanulaceae. 



Campanula lasiocarpa Cham. White Pass (Williams); 

 the Dome, Klondike-Indian Divide (Tarleton). 



Campanula aurita Greene. This species is closely related 

 to Campanula cxpansa Rudolph, of Siberia, which has been 

 referred by Ledebour to the Wahlcnbcrgia homallanthina of 

 De Candolle. Both plants agree in having a rotate deeply 

 divided corolla and a strongly upcurved style. It does not 

 seem to me that they are properly referable to the Old World 

 genus Wahlenbcrgia. In the characters of style and co- 

 rolla they resemble the East American Campanula Ameri- 

 cana L. 



Dawson (R. S. Williams, July 29, 1899); also collected 

 by Tarleton at Dawson, Aug. 19, 1899, no. 185a and 185b.
