ACCOUNT OF GENUS SEDUM AS FOUND IN CULTIVATION. 289 
Var. densirosulatum Praeger in Journ. oj Bot., 57, 57, 1919 (fig. 170). 
Rosettes dense, twice as broad as long. Leaves smaller than type (i by -j^ inch 
by \ inch), spathulate, acuminate, very glaucous, tipped purple. Stem much 
shorter (2 to 3 inches), branched almost from the base ; ultimate racemes short 
inch), flowers crowded, on shorter pedicels ; whole inflorescence rounded, dense, 
about 2 inches long and broad. Calyx and corolla more mottled with red. Petals 
straighter, less thickened in upper part, so that the cavity in the lower part 
is less pronounced (fig. 170, a). Scales narrower (fig. 170, h).

A winter annual, appearing in summer or autumn and flowering 
early the following summer. The tallest of the annual Sedums, 
growing sometimes a foot in height, and the most branched, its 
slender pyramidal growth and starlike white flowers separating it 
from any other cultivated species. Where introduced, it often 
maintains itself by self-sown seedlings. 
Description. — Annual, or occasionally biennial, tall, slender, much-branched, 
usually hairy ; young plants lowly, forming a loose rosette of stalked leaves J 
inch long ; petiole | inch, flat, nearly linear, lamina | inch long, ovate, very 
blunt. Stem a foot or less, erect, hairy, dotted red, with wide-spreading, 
ascending lateral branches. Leaves alternate or opposite, or in whorls of 
3 or 4, flat, fleshy, smooth, linear-obovate, sessile, red-spotted ; the root-leaves 
obovate, with a distinct petiole. Inflorescence a loose panicled cyme, occupying 
the whole plant. Buds slender, ovate, acute, ribbed. Flowers 5-parted, f inch 
across, on long pedicels. Sepals green, linear-lanceolate, hairy, separate nearly 
to the base. Petals white, wide-spreading, keeled, lanceolate, with an attenuate 
acute point, hairy on back, thrice the sepals, nerve red, depressed on face. 
Stamens f the petals, spreading, filaments white, anthers purple. Scales small, 
yellowish, quadrate, emarginate. Carpels spreading, greenish, tinged red, equalling 
the stamens ; slightly spreading in fruit. 
Flowers June- July. Hardy. 
Habitat. — Central and Southern Europe, on shady rocks, &c. 
Naturalized in Buckinghamshire (Sowerby, " Engl. Bot." ed. 3, 4, 63). 
Known in cultivation as early as 1610, but only occasionally 
found in gardens. I saw it at Leipzig, and with Mr. E. A. Bowles at 
Waltham Cross, and received it from Oxford and Wisley. Of late 
years, S. stoloniferum, a very different plant (see p. 196), has been sold 
under the name of S. Cepaea by some nurserymen in England. 
Cepaea is a pre-Linnean name for the plant.
