REVISION OF EPIIOBIUM. 95 
passing into the next variety. — Specimens examined from 
New Brunswick and various parts of Canada and British 
America, Maine, New Hampshire, Massachusetts, New York, 
Pennsylvania, Michigan, Wisconsin, Minnesota, Montana, 
Colorado, Utah, Oregon, and California. — Plate 21. 
Var. OCCIDENTALE. — Remotely leafy, especially the 
mostly strict very glandular branches; leaves more trian- 
gular-lanceolate, 50 mm. long on the main stem, erect, 
prominently denticulate, very short-stalked, those of the 
inflorescence small and acute at both ends. — Vancouver 
Island and British Columbia to central California, and 
Nevada? ( Shockley, 509, in Hb. Gray.).— So far as can be 
judged from fragments of the inflorescence kindly sent me 
by Dr. Urban, the plants raised in the Berlin Garden from 
Montana seed ( Arausse, 1882), and referred to #. Chilense 
by Haussknecht (Monogr. p. 273), may belong here; for 
although the lower leaves are described as different, the 
upper leaves are acute at base and evidently stalked. — 
Plate 23. 
Plants from Utah, Arizona, etc. (Palmer, 1877, Beaver 
City, No. 156), Siskiyou county, California (Pringle, 1881, 
no. 110), Boulder, Col. ( Henry, 1874), etc., have the coma 
dingy, and the foliage and even the lower part of the stem 
very glandular-puberulent, and in aspect they approach 
Novo-Mexicanum. They appear to be comparable with the 
most glandular form of paniculatum, already referred to. 
This variety, which appears to be best developed in the 
upper Pacific region, sometimes comes too near EH. Francis- 
canum, but differs in its usually smaller flowers less corym- 
bosely clustered and more acute at base, and in its shorter 
glandular pubescence. It passes into the type by numer- 
ous specimens from California and the adjacent and 
northern region, some of which, however, are more cinereous. 
than the eastern form of the species.* 
* —, EXALTATUM, Drew, Bull. Torrey Bot. Club, xvi. (1889), 151, which 
Professor Greene informs me is the common tall plant of the northwest 
coast, would appear to be this variety, were it not for the fact that.
