228 ONAGRACE. EPILOBIUM. 
sharply but remotely denticulate, usually crisp-ciliate, gradually narrowed 
to the conspicuous cuneately winged base; inflorescence sparingly glandu- 
lar; flowers rather few, somewhat nodding: petals about # lines long pale 
or rosy; capsule rather slender, 2U lines long, on slender peduncles much: 
shorter than the leaves: seeds nearly beakless; coma dingy. Alaska and 
the adjacent islands, perhaps Washington. 
+ + + + + QOften more or less cespitose by leafy stolons, other- 
wise simple or nearly so, sometimes apparently annual. 
++ Seeds smooth or at most undulate-areolate except in forms re- 
ferred to Oregonense. 
= Leaves rather ample. 
E. alpinum L. Sp. 348, in Part. Mostly a span or two high, simple, 
inflorescence and decurrent lines nearly glabrous; leaves thin and delicate, 
pale green, 20 lines long, sub-elliptical, rather obtuse, subentire to some- 
what sharply serrulate, gradually narrowed to slender petioles: flowers 
few, suberect. in the upper axils; petals a line or more long, white or rosy- 
tipped; capsule very slender, erect or ascending, about 2 incles long, their 
peduncles rather slender and about equalling the subtending leaves or 
stouter and as long as the capsules: seeds smooth gradually attenuated at 
apex, with veiny beak. In the high mountain swamps, Brit Columbia to 
California and Eastern States. 
= = Leaves narrow, subentire. 
E. Oregonense Hausskn. Monogr. Epilob. 270. 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 6-10 lines long 
crowded t elow, remote and very small above, narrowly oblong-ovate or the 
uppermost linear very obtuse, remotely denticulate, somewhat cuneately 
narrowed at base but sessile: flowers few, strictly erect; petals deep violet, 
4 lines long; capsules about 2 inches long slender strict, much surpassin 
the summit of the stem, their very slender peduncles of nearly equa 
length, far exceeding the subtending leaves; seeds smooth, blunt.. Bogs, 
Oregon to Brit. Columbia. 
Var. (2) gracillimum Trel. Sp Epilob. 105. A span to nearly a foot. 
high, cespitose, very slender; quickly erect and hardly bent at top, glab- 
rous except the very minutely and sparingly glandular inflorescence: 
leaves shorter than the internodes, narrow, entire keeled, on the midrib; 
flowers few, nearly erect; petals white or pale, 3 lines long; seeds evi- 
peated papillate, the beak scarcely hyaline Bogs, Washington to Cali- 
ornia. 
E. anagallidifolium Lam. Dict ii, 376. About a span high, at length 
rather densely cespitose, otherwise unbranched, stems very slender, 
strongly nodding at apex, somewhat crisp-hairy at least in lines; leaves 5-10 
lines long, all but the lowermost very narrowly ovate or oblong, rather 
obtuse, entire or remotely denticulate; flowers few, crowded at apex 
somewhat nodding; petals lilac to violet, 2 lines long; capsule one inch 
long, slender, surpassing the end of the stem, their rather slender pedun- 
cles shorter than the leaves or when only one or two are present equalling 
the capsules; seeds short-beaked; coma somewhat dingy. Arctic America 
to California, also in the Old World. 
++ +» Seeds often coarsely papillate, nearly one-half longer than 
in the preceding group 
E. clavatum Trel. 1 c. 111. A span high, mostly densely cespitose, the 
slender stems ascending, glabrate to sparingly glandular throughout; leaves 
8-10 lines long, broadly ovate, very obtuse, mostly rounded to evident peti-
