ACCOUNT OF GENUS SEDUM AS FOUND IN CULTIVATION. 289 



Var. densirosulatum Praeger in Journ. of Bot., 57, 57, 1919 (fig. 170). 



Rosettes dense, twice as broad as long. Leaves smaller than type (i by -^ inch 

 by J inch), spathulate, acuminate, very glaucous, tipped purple. Stem much 

 shorter (2 to 3 inches) , branched almost from the base ; ultimate racemes short 

 (J 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, b).

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 cjmie, occupying 

 the whole plant. Buds slender, ovate, acute, ribbed. Flowers 5-parted, | inch 

 across, on long pedicels. Sepals green, linear-lanceolate, hairy, separate nearly 

 to the base. Petals white, wide-spreading, keeled, lanceolate, with an attenuate 

 ^cute point, hairy on back, thrice the sepals, nerve red, depressed on face. 

 Stamens | 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.
