A handsome species, known at once by its pinkish, 4-parted flowers 

 densely set on radiating recurved branches at the summit of the 

 stem. The leaves are fresh green and linear, with a forked spur at 

 the base, and the plant does not creep. 



Description. — Evergreen, perennial, forming a bright-green tuft. Stems 

 erect or trailing, not creeping, all eventually flowering, smooth, round, slender, 

 red, bare and branched below. Leaves crowded, green, ascending, linear, 

 terete, blunt, about f inch long, produced below into a forked spur. Inflorescence 

 3 to 4 inches across, of 3 to 5 recurved simple leafy branches with a 5-parted 

 flower in the fork. Flowers 4-parted (except the central one), sessile, rosy purple, 

 \ inch across. Buds ovate, blunt, strongly 4-angled. Sepals green, fleshy, 

 lanceolate, blunt, separate nearly to the base. Petals rosy purple, lanceolate, 

 acute, keeled, twice the sepals. Stamens shorter than the petals, filaments 

 rose, anthers red, oblong. Scales small, whitish. Carpels slender, rose, 

 equalling the stamens, erect, later spreading, tapering into the long styles. 



Flowers July-August. Hardy. 



Habitat. — United States, Missouri to Virginia and Texas. 



One of the best Sedums in cultivation, its large, claw-like 

 inflorescences of rosy-purple flowers being produced abundantly and 

 for a long period. The plant is remarkable in its genus for its love 

 of a damp habitat ; the finest plants I have seen have been on the 

 edge of water, and in my own garden, where there is a light, porous 

 soil, I have to grov/ it in a pot plunged in a tub. The plant has been 

 long known in gardens, and is generally correctly named ; it is 

 unmistakable. 



Found in most collections. The name refers to its pleasing 

 appearance.

Here belongs a characteristic group of Mexican Sedums, most of 

 which are in cultivation. 5. nutans, the most massive of all Sedums, 

 has been placed by Rose in a separate genus, Cremnophila, but its 

 flowers present no distinct generic character. 5. praealtum, den- 

 droideum, and confusum form a compact closely related group.
