REVISION OF EPILOBIUM. 109 
== Habit of EF. anagallidifolium, with narrow subentire leaves 
(these more toothed in pseudo-scaposum). 
36. E. OreGonensr, Hausskn.—A span high, with 
few sterile shoots at base, erect even as to the apex, glabrous 
except for very sparing glandular hairs in the inflorescence ; 
leaves 15 to 20 mm. long, crowded below, remote and very 
small above, suberect, narrowly oblong-ovate or the 
uppermost linear, very obtuse, remotely low-denticulate, 
somewhat cuneately narrowed at base but sessile, rather 
delicate and with slightly evident lateral veins ; flowers few, 
strictly erect; petals deep violet, about 8 mm. long; 
capsules about 50 mm., slender, strict, much surpassing the 
summit of the stem, their very slender peduncles of nearly 
equal length and far exceeding the subtending leaves; 
seeds (immature) smooth, blunt, apparently beakless. — 
Monogr. 276, pl. 14, f. 66. — Bogs, Oregon (Hail, 1871, 
no. 179) to British Columbia (Swamp River, Macoun, 
1875, no. 1921 in part). — Plate 25. 
Young Californian plants referred here with considerable 
doubt, have small but more ovate leaves drying brownish 
(Bolander, nos. 1786 and 4965; Lemmon, 1875 —the 
leaves in whorls of 3 in one specimen). Here also, per- 
haps, would be referred plants collected in Tulare county, 
California (Palmer, 1888, 218 in part, and 220). In the 
latter, especially, the internodes lengthen and the leaves 
are very narrow above, as in the type, but the lower leaves 
are short and ovate. Except for their larger size and more 
erect habit, however, these round-leaved plants are not 
unlike some of the more erect European forms of anagallidi- 
folium, —e. g. a specimen from the Clova Mts., Scotland, 
collected by Greville in 1839. 
Var. ? GRACILLIMUM. — A span to nearly a foot high, 
often quite cespitose, very slender, quickly erect and hardly 
think it best to follow Professor Haussknecht in adopting a new name 
for what is left of the original alpinum, but prefer still to employ for it 
the name given it by Linneus. Nor should I follow H. and J. Groves in 
allowing the latest name, lactiflorum, to stand, while displacing anagalli- 
difolium.
