Plate D. 

 E. l-oseura, var. Benth. Handbook Brit. Fl. p. 208. 



Stolons first produced late in autumn, appearing above ground 

 and bearing sub-sessile rosettes of green leaves. Stem erect, simple 

 or slightly branched, with 4 indistinct raised lines, clothed with short 

 incurved hairs. Lower leaves approximate, opposite ; upper ones or 

 not unfrequently all alternate; all shortly stalked, with the margins 

 of the petioles decurrent, so as to form faint raised lines on the 

 stem, oblong- or strapshaped-elliptical, wedge-shaped at the base, 

 obtuse at the apex, regularly and rather remotely dentate-serrate. 

 Bracts alternate, resembling the leaves. Flowers numerous, slightly 

 drooping before expansion. Calyx-segments lanceolate, acute. 

 Petals longer than broad, half as long again as the calyx-segments. 

 Stigma 4-partite with the segments spreading. Pod clothed with 

 short incurved hairs. Seeds oblanceolate-oblong-ovoid, rounded 

 above, somewhat acute below, finely tuberculate. Plant sub- 

 glabrous except the stem (especially the upper part of it), pods, 

 calyces, and veins and margins of the leaves, which are hairy. 



By road-sides and in dry waste places. Bare. Near Plymouth, 

 Devon ; Stapleton and Hanham, Bristol ; and at Tintern, Mon- 

 mouthshire ; formerly also at Long Ditton, Surrey. 



England. Perennial. Summer and Autumn. 



Stem 1 to 3 feet high. Leaves I± to 2 inches long, with the 

 petioles longer in proportion than in E. montanum, with the sides 

 more parallel, the margins more equally serrate, with the base 

 entire for a greater distance; the calyx-tube is longer when in 

 flower, and has the segments much more acute ; the flowers are 

 scarcely so large, deeper rose ; and in winter the rosettes have the 

 leaves spreading, not erect, as those of E. montanum. The leaves 

 are of a grevish-green, but have frequently the red tinge which 

 occurs also in E. montanum, and the stem and one side of the 

 calyx are almost always tinged with purplish-red. 



The lines on the 'stem of this species are sometimes very in- 

 distinct.
