100 MISSOURI BOTANICAL GARDEN. 
Young specimens doubtfully referred here occur in the 
Gray herbarium from Labrador (Allen, 1882, no. 11, as 
E. coloratum), but I am unable to find specimens authen- 
ticating the general distribution ascribed to the species by 
Professor Haussknecht, on whose authority it was admitted 
to the sixth edition of Gray’s Manual. 
The separated decurrent lines of some Arctic specimens 
are more or less wing-like, then bearing prominences 
similar to the marginal teeth of the leaves, from which the 
‘ specific name is said to be derived.

25. E. BREVIstyLUM, Barbey. — Slenderer and _ less 
pubescent ; leaves scarcely 40 mm. long, ovate or ellipiticals 
more loosely and uniformly distributed along the stem, less 
toothed, drying pale, the uppermost reduced and surpassed 
by the nearly glabrous capsules; seeds slightly smaller, 
tapering above, the papille similar; coma less dingy. — 
Brewer & Watson, Bot. Calif. i. (1876), 220; Barbey & 
Cuisin, pl. 13.—Springs, etc., Washington to California. — 
Apparently too close to the last by specimens from British 
Columbia and Colorado ( Vasey, 1868, No. 184; Engel- 
mann, 1881), which are rather in the region of Drum- 
mondii. — Plate 30. 
I am unable to find the original specimen in the Gray 
herbarium, but the figure of Barbey & Cuisin seems to 
represent the form here described, which is of very differ- 
| ent appearance from the large Arctic form of glandulosum 
/ to which Haussknecht doubtfully joins it. 
E. affine, 8. fastigiatum, Nuttall in Torr. & Gr. FI. i. 
489, which might be thought to refer to this form, proves 
(at least in Hb. Torrey.) to be E. glaberrimum, var. lati- 
folium, with leaves rather more dentate than usual. 
26. E. urstnum, S. B. Parish, in herb. — A span to a 
foot high, slender, both leaves and stem below pilose with 
rather remote and spreading long white hairs, the inflor- 
escence minutely glandular-pubescent; leaves less than 30 
mm. long, rather uniformly and in larger plants remotely
