228 ON AG RACEME. 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 4 lines long pale 

 or rosy ; capsule rather slender, 20 lines long, on slender peduncles much 

 shorter than the leaves: seeds nearly beakless; coma dingy. Alaska and 

 the adjacent islands, perhaps Washington. 



+- +- ■*• -*- ■*- Often 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-lu lines long 

 crowded below, 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 surpassing 

 the summit of the stem, their very slender peduncles of nearly equal 

 length, far exceeding the subtending leaves; seeds smooth, blunt. Bogs, 

 Oregon to Brit. Columbia. 



Var. (?) gracillimnm 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, 8 lines long; seeds evi- 

 dently papillate, the beak scarcely hyaline Bogs, Washington to Cali- 

 fornia. 



E. anagallidifolium Lam. Diet 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-
