O44 ENGLISH BOTANY. 
Stem erect, ascending or prostrate, with the internodes straight 
(not regularly arched), usually rooting only at the lower nodes. 
Apiculus of the ripe achenes about one-eighth of the length of the 
whole, obtuse. 
Var. a. sub-erectus. 
Stem decumbent and rooting only at the very base, terminal 
portion erect. 
Var. 2. pseudo-reptans. 
R. reptans, Zhuil. (non Linn.) 
Stem procumbent, rooting at the nodes; the apex alone ascend- 
ing. Leaves usually narrower than in var. a, and the whole plant 
smaller. 
In ditches, marshes, and wet pastures. Very common through- 
out Britain. Var. 6 much less frequent than var. a. 
England, Scotland, Ireland. Perennial. Summer, Autumn. 
Root of white simple fibres. Stem about 1 to 2 feet high in 
var. a, 3 to 9 inches in var. 8. Leaves very variable in shape: 
those at the bottom of the stem broadest, varying from broadly 
ovate to narrowly elliptical, lanceolate; stem leaves with the base 
of the petiole amplexicaul; upper leaves sessile, sub-amplexicaul, 
usually ligulate. Peduncles slightly pubescent. Flowers in an 
irregularly corymbose cyme in var. @, or nearly solitary in var. . 
4 inch to ? inch in diameter. Petals obovate, pale yellow. Achenes 
roundish, greenish olive, appearing finely granulated under a power- 
ful lens, with an extremely short, blunt apiculus. 
The perennial root, the stem decumbent at the base and much 
firmer in texture, the more glaucous colour, larger flowers, and 
smooth green achenes, are sufficient distinctions between the 
broader forms of the present plant and the preceding.
