scales orange, carpels turning pink, fruit red. Origin unknown to 

 me ; it has been much distributed in recent years and is a very useful 

 plant for the rock garden.

This little-known plant in flower strongly resembles S. album, and 

 it has the habit of that species, but the leaves are widely different, 

 their flattened, rather rhomboidal shape and dull greyish surface (due 

 to fine pubescence) giving the plant an appearance quite distinct. 



Description. — A small evergreen, creeping, puberulous perennial, forming 

 a greyish mat, flushed red in exposure. Stems creeping, with many short, 

 ascending, barren shoots, and flowering shoots 4 to 6 inches high, puberulous 

 below, glabrous above. Leaves of barren shoots imbricate, arranged in about 

 5 spiral rows, thick, blunt, sessile, ovate-rhomboidal, J inch long, puberulous, 

 dull greyish green tinged red ; those of the flower-shoots similar, more distant. 

 Inflorescence corymbose, much branched, i\ inch across, lowest branches 

 emerging about 2 inches below the summit. Flowers many, small, \ inch across, 

 and, like the inflorescence, much resembling S. album. Calyx green, glabrous, 

 only slightly fleshy, lobes triangular, blunt, equalling the tube. Petals white, 

 ovate-lanceolate, acute, thrice the sepals. Stamens equalling the petals, anthers 

 white, filaments purple. Scales minute, yellowish, broadly spathulate. Carpels 

 equalling the stamens, white, erect, styles at first erect, later curving outwards. 



Flowers June- July. Hardy. 



Habitat. — Spain and Portugal. 



Though described over seventy years ago, I find no record of 

 the plant in cultivation. It was collected in Spain by F. Sundermann , 

 of Lindau, a few years ago, and came from him as " Sedum sp. Sierra 

 Nevada."

A plant of about the size of album, or smaller, but tufted, not 

 creeping. Distinguished by its densely hairy leaves (which are 

 sub-terete and bluntly oblanceolate) , and usually pure white, starry 

 flowers. The only other Sedum in cultivation with such hairy, thick 

 leaves is S. dasyphyllum var. glanduliferum, but in this the leaves 

 are opposite, glaucous, shorter, and thicker, not alternate and green. 



Description. — A small, tufted, evergreen perennial, green (reddish in 

 exposure), hairy throughout with glandular viscous hairs. Barren stems ascend- 

 ing, about I inch long, with the leaves aggregated at their tips. Flowering 

 stems 2 to 3 inches high, erect, leafy, hairy. Leaves oblanceolate, blunt, sessile, 

 very fleshy, hairy, especially near the tips, f inch by |r inch, elliptic in section. 

 Inflorescence few-flowered, usually of 2 branches, drooping in bud, pedicels 

 equalling or shorter than the flowers. Buds ovate, acute. Flowers white or 

 tinged red, ^ inch across. Sepals erect, lanceolate, green, fleshy, hairy. Petals 

 oval, with a short claw, apiculate, wide-spreading or reflexed, more than twice 

 the sepals, white, with a prominent red nerve on the hairy back. Stamens 

 spreading, shorter than the petals, filaments white, anthers dark purple. Scales
