flushed with red, wide-spreading, later sharply reflexed. oblong, acute, keeled, 

 equalling or shorter than the longest sepal. Stamens nearly erect, equalling 

 the petals, filaments whitish, anthers purple. Scales yellowish, quadrate. 

 Carpels green, slightly spreading, equalling the stamens, tapering into erect 

 styles ; the carpels become deep red in fruit. 



Flowers December (gentle heat). Not hardy at Dublin. 

 Habitat. — Sierra Madre, Monterey, Mexico. 

 Received from Washington, New York, and Edinburgh. 

 The name refers to the red colour assumed by the fruit. 



91. Sedum longipes Rose (fig. 115). 



5. longipes Rose in Bulletin New York Bot. Garden, 3, 43, 1903. 

 "N. Amer. Flora," 22, 70. 



A curious Sedum, easily recognized by its long, low-arching, leafy 

 branches rooting at intervals, small bright-green leaves very convex 

 above, and small few reddish flowers with large forked scales. 



Description. — Glabrous, bright-green, perennial. Roots fibrous. Stems 

 smooth, round, green mottled red, long-arching or decumbent, rooting at 

 intervals, often with purple aerial roots, branching at the rooting points or 

 towards the endg, ends of branches erect, slender, bearing terminal flowers. 

 Leaves alternate, rather distant, very fleshy, sessile, slightly spurred, obovate or 

 spathulate, entire, very blunt, reflexed, very convex above, flattish below, up to 

 I inch long by -^ broad, diminishing at ends of shoots to \ long. Inflorescence 

 of several (usually 2) terminal flowers on long filiform pedicels. Buds broadly 

 ellipsoid, blunt. Flowers reddish, few, inconspicuous, -^ inch across. Sepals 

 green, fleshy, wide-spreading, ovate-lanceolate, blunt, with a blunt spur. Petals 

 ovate, blunt, patent, red in upper part, becoming silvery white near base. 

 Stamens wide-spreading, nearly equalling the petals, filaments whitish, anthers 

 orange. Scales very large, spreading, tips reflexed, coloured like the petals, 

 forked in upper part, the branches widely divergent, each with 2 or 3 reflexed 

 teeth. Carpels short, erect, green ; styles short, reddish, with spreading tips. 



Flowers January (gentle heat). Very sensitive to frost. 



Habitat. — Sierra de Tepoxtlan, Mexico. 



A very distinct plant, remarkable both on account of its habit 

 and its flowers. Planted where frost is excluded, it soon forms a tangled 

 mass several feet across, the shoots arching for half a foot or so, then 

 rooting and branching, and the branches arching similarly. The 

 shoots of the following year arise from ovoid buds produced near the 

 base of the stem, or at other points of the stem, especially where 

 roots are formed. In a cold frame the stems get killed off by frost, 

 the buds alone remaining (as often happens with 5. sarmentosum in 

 the open) . The young leaves have a pimpled surface ; the hypogynous 

 scales are very remarkable and abnormal for the genus. Flowers 

 solitary according to Rose ; in pairs in my plants ; in clusters of 

 as many as six in a specimen of Pringle's in British Museum. 



The large forked and toothed scales are very unusual in the genus. 

 One of them is shown in the figure (fig. 115, a) where the carpel is 

 foreshortened to show the full size of the scale. 



In cultivation in Britain the flowers are very pale, no doubt owing 

 to the weakness of the winter sunlight ; but in dried Mexican specimens 

 they are of a deep purple.
