12 ENGLISH BOTANY. 



green leaves. Stem erect, simple or branclied, round, without evi- 

 dent raised lines, pilose. Leaves at the base of the stem opposite, 

 those above the middle generally alternate, sessile, the upper ones 

 not at all anii)lcxicaul or dccurront, oblong-lanceolate, rounded at 

 the base, remotely and finely callously denticulate. Bracts alter- 

 nate, resembling the leaves. Flowers numerous. Calyx-segments 

 oblong, acute but not ai)iculate. Petals longer than broad, about 

 one-half longer than the calyx-segments. Stigma 1-partite, with 

 the segments spreading but not revolute. Pod clothed with very 

 short articulated hairs. Seeds oblaneeolate-ovoid, rounded at both 

 ends, finely tubercular. Plant pilose with its imbescence glandular 

 above, or sub-glabrous. 



In wet places, by the sides of ditches, streams, and ponds. 

 Common, and generally distributed throughout the kingdom, 

 extending further North than the preceding. 



England, Scotland, Ireland. Perennial. Summer 

 and Autumn. 



This species was supposed by Linnaeus to be merely a variety 

 of E. hirsLitum, but it is a much smaller plant, 1 to 3 feet high, 

 with the leaves rarely above 2 inches long, more ascending, some- 

 times many of them alternate, the upper ones not at all am- 

 plexicaul or dccurrent, more variable in shape (from strap-shaped 

 to broadly lanceolate), though generally having more or less of an 

 oblong form ; the flowers much smaller, f inch across, pale pur- 

 plish-rose ; the style not exceeding the stamens, the stigmas not 

 revolute ; the pilose hairs shorter and more woolly ; and it may be 

 readily known from E. hirsutum by the absence of the thick fleshy 

 wiiite stolons. 



The sub-glabrous state, E. rivulare of Wahlenberg, occurs 

 occasionally ; but all intermediate forms between it and the ordi- 

 nary hairy form are to be found, and it seems scarcely separable 

 even as a variety. AVhen most of the leaves are alternate it is E. 

 intermedium of Merat.

 Stolons first produced late in autumn ; when subterranean 

 short, with fleshy white and pink imbricated scales ; when appear-
