REVISION OF EPILOBIUM. 105 
gent, scarcely 25 mm. long, broadly ovate to ovate- 
lanceolate, mostly subcordately contracted to the very 
short base. — Bot. Calif. i. (1876), 220.—£. glaberrimum, 
Hausskn. Monogr. 252. — E. affine, f. fastigiatum, Nutt. in 
Torr. & Gr. FI. i. (1840), 489, as to the specimen in the 
Torrey herbarium. — Oregon to California and the Wahsatch 
Mountains of Utah, —apparently most developed about the 
outer range of the species. — Small specimens approach #. 
Hornemanni in habit. — A restoration of Nuttall’s name 
would cause the variety to be known as Z. glaberrimum, 
var. fastigiatum (Nutt. ).— Plate 39. 
++ ++ Puberulent, at least in lines: seeds more fusiform, usually some- 
what beaked above. 
= Seeds papillate. 
E. OrgGaNum, Greene. —A couple of feet high, rather stout, simple 
or with ascending branches, glabrate and glaucous below, glandular- 
puberulent above; leaves ascending, as much as 75 mm. long, lanceolate, 
obtuse, closely denticulate, cuneately subsessile or abruptly rounded to 
short winged petioles, veiny; flowers rather numerous, erect in the axils 
of the reduced upper leaves; calyx-tube 3 mm. long, rather narrowly 
funnel-form: petals violet, 8 to 12 mm. long; style about equalling the 
corolla, pubescent near the apex and on the outside of the four widely 
divergent stigmatic lobes; capsules nearly erect, 40 mm. long, usually 
subsessile; seeds oblong-fusiform, obliquely pointed at base, very 
shortly pellucid-beaked, .25 x .75 to 1 mm.; coma white. — Pittonia, i. 
(1889), 225. — #.glaucum, Howell, List for 1887, p.3, not Phil. & Hausskn.— 
Grant’s Pass, Oregon (Howell, July 1887, distributed as nos. 699 and 
1139).— Specimens distributed as no. 695 by Howell in the same year 
appear to be a slenderer form of the same, and in habit and innovations 
closely approach E£. glaberrimum. Specimens of the typical numbers in 
Hb. Dept. Agr. have short sobols somewhat rosuliferous at end, but 
most of those that I have seen do not show the innovations. — Plate 40. 
I cannot resist the impression that HZ. Oreganum is a hybrid of glaber- 
rimum, the vegetative characters suggesting adenocaulon as a possible 
other parent. 
32. E. Hornemanni, Reichenb. — Mostly a span or two 
high, ascending, unbranched, somewhat crisp-hairy in the 
inflorescence and along the decurrent lines, or slightly glan- 
dular at top, otherwise glabrate; leaves about 25 mm. long, 
subascending, elliptical-ovate, mostly very obtuse, nearly 
netire to remotely serrulate, the lower cuneately narrowed,
