Usually much branched above and minutely hoary-pubescent, 1--2° high; leaves linear-lanceolate, tapering to a short but distinct petiole, acutish; flowers numerous, pale; capsules hoary, on pedicels as long as the leaves. (E. palustre, var. lineare, _Gray_, mainly.)--Bogs, N. Eng. to Penn., Iowa, and northward. 3. E. stríctum, Muhl. Erect, 1--2½° high, densely beset with soft spreading somewhat glandular white hairs; leaves broader, more obtuse and with evident veins, very short-petioled or sessile; pubescence of the capsule soft and spreading. (E. molle, _Torr._)--Bogs, Mass. to Minn., south to Va. and Ill. [*][*][*] _Stigma clavate; stem somewhat quadrangular with 2--4 ridges or hairy lines decurrent from some of the leaves._ [+] _Tall and mostly branching, many-flowered; leaves rather large, toothed, not revolute, the lower opposite; seeds papillose._ 4. E. coloràtum, Muhl. Somewhat hoary-pubescent above or glandular, 1--3° high; leaves lanceolate, sharply serrulate or denticulate, acute, narrowed to conspicuous petioles; flowers pale, more or less nodding; peduncles shorter than the leaves; seeds dark, unappendaged; coma cinnamon-color.--Wet places, common. 5. E. adenocaùlon, Haussk. Differs in its more glandular pubescence above, the often blunter and less toothed leaves abruptly contracted to shorter petioles, flowers erect, paler seeds with a slight prolongation at top, and a merely dingy coma.--Wet places through the Northern States. 6. E. glandulòsum, Lehm. Subsimple; pubescence above not glandular; leaves ovate-lanceolate, mostly abruptly rounded to a sessile base and more glandular-toothed; seeds larger.--Canada to the mountains of N. C. (_fide_ Haussknecht). (Asia.) [+][+] _Mostly low, slender and simple (except forms of n. 10); leaves chiefly opposite, less toothed; flowers few, nodding; seeds appendaged at the apex._ [++] _Seeds areolate but not papillose; leaves not revolute._ 7. E. anagallidifòlium, Lam. Glabrate, a span high or less; leaves erect or ascending, about equalling the internodes, elliptical-oblong to narrowly obovate, entire or the upper denticulate, tapering to short petioles; flowers purple; sepals rather obtuse; capsules glabrous on peduncles exceeding the leaves.--White Mts. and Adirondacks (_fide_ Haussknecht). (Eu.) 8. E. lactiflòrum, Haussk. Glabrous except the pubescent lines, 6--12´ high, with elongated internodes; leaves elliptical or the lowest round-obovate, slightly repand-denticulate, obtuse, tapering into mostly elongated petioles; flowers smaller, white; sepals more acute; seeds more prominently appendaged.--White Mts., and northward (_fide_ Haussknecht). (Eu.) [++][++] _Seeds papillose-roughened._
