marked in habit, and in the character of the root. It is related to D. 
bicolor, though not very intimately. 
219. Cerastium subulatum Greene, l. c., p. 36. 
Perennial, the sub-erect flowering stems 6 to 10 inches high, ending 
in a peduncled and few-flowered cyme, this in age almost equalled by 
the upright very leafy sterile shoots; the leaves of the latter linear or 
subulate-linear, twice the length of the internodes, spreading or the 
lowest recurved, less than a line wide, puberulent, or marginally 
somewhat villous, the stem retrorsely villous: bracts of the cyme short, 
broadly subulate; calyx glandular-hirtellous and with some scattered 
villous hairs: capsule short, only the teeth exserted and bent upward. 
British Columbia: Chilliwack Valley, J. M. Macoun, 20 June, 
1902, the specimens in mature fruit; the label bearing the number 
34023. 
220. Cerastium alsophilum Greene, |. c., p. 37. 
Perennial, the slender and sparsely leafy flowering stems a foot 
long or more, ending in a rather strict many-flowered cyme, the sterile 
shoots few, long or short, only loosely leafy, weaker than the others; 
the whole herbage green and apparently glabrous, a lens disclosing 
hirtellous hairs on all the parts, but most obviously on the stems: leaves 
all spatulate-linear, acute, thin, spreading: bracts of the cyme subulate: 
pedicels filiform, the primary ones an inch long or more, minutely 
glandular-hirtellous: sepals very acute, thin and rather faintly 1-nerved, 
sparingly glandular-villous; petals thrice the length of the sepals: capsule 
unknown, 
British Columbia: This species, very well marked in habit, foliage, 
pubescence, &c. is also from the Chilliwack Valley, by Mr. Macoun. 
There are two sheets of it, one bearing the number 34020, the other 
34021. The thin foliage and loose habit indicate it to be an inhabitant 
of shady places. 
221. Cerastium nitidum Greene, l. c., p. 37. 
Perennial, 6 inches high, slender, sparsely leafy, the younger stems 
often purplish, the older whitish, shining and quite glabrous below, 
above more or less pubescent in lines: leaves oblong-linear, acute, mostly 
less than !/, inch long, suberect on the flowering stems, spreading on 
the sterile shoots, glabrous in every part except for occasional long 
hairs at the very base: inflorescence scarcely cymose, the flowers 
often solitary, sometimes 4 or 5: sepals thin, scarious tipped, sparingly 
pubescent, faintly nerved: petals thrice as long, obcordate: capsule 
not seen. 
British Columbia: Habitat of the foregoing, though of a subalpine 
altitude (5500 ft.); collected by Mr. Macoun, 29. Aug. 1901. (No. 34022). 
222. Carduus Macounii Greene, |. c., p. 38. 
Perennial, slender, simple or branched above, 1 to 3 feet high, the 
stem and also the leaves beneath arachnoid-hoary; leaves of oblong
