Family CAPRIFOLIACEAE. 
“Viburnum pauciforum Pylaie. Dawson and'Miles Cajion 
(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 Z. doreadis in 
its funnelform, not campanulate corolla. 
Family VALERIANACEAE. 
Valeriana bracteosa Britton, sp. nov. 
Similar to V. sylvatica and V. uliginosa, 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 lastocarpa Cham. White Pass (Williams) ; 
the Dome, Klondike-Indian Divide (Tarleton). 
Campanula aurita Greene. This species is closely related 
to Campanula expansa Rudolph, of Siberia, which has been 
referred by Ledebour to the Wahlenbergia 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 Wahlenbergia. In the characters of style and co- 
rolla they resemble the East American Campanula Amert- 
cana L. 
Dawson (R. S. Williams, July 29, 1899); also collected 
by Tarleton at Dawson, Aug. 19, 1899, no. 185a and 185b.
