ACCOUNT OF GENUS SEDUM AS FOUND IN CULTIVATION. 299 



Of the plants raised, one flowered in the first year and then 

 died In this the flowers had only five stamens, and the in- 

 florescence proved abnormal, being very lax and leafy, with 

 large flowers. The rest flowered in the following season, and the 

 flowers examined had ten stamens. Misled by this, I described the 

 plant as new (as above). Further examination of this material 

 shows that the number of stamens in the flowers is not constant. 

 As the stamens in the type material and in other gatherings in the 

 Edinburgh Herbarium (which like the type are of Maire s gather- 

 ing about Tong-tchouan) are five, it appears that my specimens 

 were exceptional.

The type is well marked by its annual duration, pmkish-glaucous 

 colour, and pinkish-white flowers with the parts in sixes. The plant, 

 however, is polymorphic, and varies as regards size, duration, hairiness, 

 and the number of the floral parts— see below. 



Description.— Generally annual, appearing in autumn ^f, spring and 

 flowerinR in Tune ; sometimes biennial ; two varieties perennial. A small 

 phSllaucous plant. 2 to 6 inches high. Stems branched below branches 

 ScSngleafy! more or less hairy. Leaves sessile, linear to ob ong-lanceolate. 

 ratSr a?ute g aucous, often reddish, fleshy, flattened, sometimes subterete, 

 AJ I inch long by iTch broad. Inflorescence a loose, leafy, flattish cyme. Buds 

 ovate acute ribl^d Flowers i inch across, usually 6-merou3. sometimes 4-, 5-, or 

 Jvloom^oZ Calyx short, green, teeth triangular, acute. Petals y^hite very

 stron1[y eSlrginSte. Carpels erect, often red. smooth or hairy ; style long, curvmg 

 outwards ; fruit stellate-patent. 



Flowers June. Hardy. 



Habitat.— From Switzerland eastward to Persia. 



Carpels sometimes glabrous (var. leiocarfum Boissier. "Flor. 

 Orient.." 2, 789), sometimes more or less hairy (var. eriocarpum Boissier. 

 loc. cit.). if starved, as when grown on a wall, it tends to produce 

 barren shoots and to lose its annual character, thus approaching var. 

 hithynicum Boissier. loc. cit. 



Var. polypetalum Boissier. "Flor. Orient.." 2, 789 (fig. 178. «)• 

 Petals 7 to 9. and other floral organs in proportion; sepals 

 lanceolate.
