and scarcely smaller than the others, all obovate-lanceolate, Ui to 4 
inches long, tapering to a broad petiole, acutish, saliently and sharply 
dentate: corymbose panicle of large more or less nodding heads little 
or not at all surpassing the leaves: involucres nearly !/; inch high, sub- 
cylindric, the linear bracts about 10; rays about as many, light-yellow, 
about 5-nerved. 
Canada: Chilliwack Valley. Collected at an altitude of 6000 feet; 
closely allied to several alpine and subalpine species of the more 
southerly Rocky Mountains, the whole forming a group of which S. Sol- 
danella may be considered typical. The heads in this new one are much 
more numerous and notably narrower than in any of the allied species. 
Its number in the Geol. Surv. collection is 26678. Its habitat, as given 
by Mr. Macoun is ,damp debris on a snow-slide*.

Resembling ©. triangularis, but leaves on shorter petioles and 
distinetly hastate, more gradually acuminate, much more deeply and 
sharply serrate-dentate, in texture much firmer and dark-green, with 
venation pale or whitish, underneath whitish tomentulose, above obscurely 
and sparsely short-hairy, but the stem densely villous-tomentulose from 
base almost to summit, this indument subfuscous: inflorescence denser 
and more fastigiate than in S. triangularis; the rays longer and very 
narrow: achenes short and slender-columnar, not narrowed under the 
pappus, this very fine and promptly deciduous. 
Canada: Chilliwack Valley. The type of this is Mr. Macoun’s 
No. 26675, collected 8 Aug., on the southern slope of the Cheam Range, 
with Bromus marginatus and Castilleia miniata, at 4000 feet. Number 
26676, collected Aug. 12th within a few yards of No. 26675, I also 
refer to it though it is far less notably pubescent, while at the same 
time it exhibits quite as strongly all those peculiarities of inflorescence, 
ray-flowers, etc., by which the species stands in contrast with S. trian- 
gularis.

Derna gesammelt und als ,T. sphaerospermum Boiss.?“ (P. Taubert, iter 
cyrenaicum, no. 441; auspice W. Barbey) ausgegeben. Habituell sowie 
durch die kleinen runden Samen steht sie dem T. sphaerospermum Boiss.

— auch nicht einmal als Unterart — mit dieser Art zu vereinigen.
