CLASS X. ORDER III. J STELLARIA. 641 



Root fibrous. Stem from twelve to eighteen inclies Ligli, slender, 

 and procumbent at the base, round, hollosv, and more or less thickly 

 clothed with soft somewhat glutinous pubescence, especially above, 

 simple, rarely brarjched below, but above divided into forked panicles. 

 Leaves mostly an inch and half long, opposite, entire, with a mid-rib 

 and slender branched veins, of a cheerful green colour, paler beneath, 

 and more or less clothed with pubescence, the upper ones sessile, ovate, 

 acute, the lower ones ovate, acute, rounded, or heart-shaped at the 

 base, and elevated upon a footstalk of greater or less length, sometimes 

 as long as the leaf. Flowers pure white, numerous, in terminal forked 

 panicles, with a solitary one from the axis of the divisions. Peduncles 

 about an inch long, slender, downy, erect in flower, recurved when in 

 fruit. Calyx in five lanceolate segments, with membranous margins, 

 smooth, or slightly downy, with three or five slender ribs. Petals 

 about as long again as the calyx, deeply divided into two narrow lobes. 

 Stamens on slender ^/a/n^n/s, with ovate yellow anthers. Stylesihxee^ 

 with obtuse stigmas. Capsules cylindrical, separating to below ,lhe 

 middle into six linear valves. Seeds numerous, small, attached to a 

 central linear elongated receptacle. 



Habitat. — Moist woods, especially in the North of England and the 

 Lowlands of Scotland. 



Perennial ; flowering in May and June. 



This species has sometimes been mistaken for Cerastium aquaticum, 

 Linn., from which, however, it is readily distinguished by its petiolated 

 heart-shaped leaves in the lower part of the stem, independent of other 

 characters. It varies considerably in the hairiness of the stem and 

 leaves, which are sometimes nearly smooth, except on the margins.
