ACCOUNT OF GENUS SEDUM AS FOUND IN CULTIVATION. 305 



lanceolate, acuminate, wide-spreading, hairy on the outside, 3 to 4 times the 

 sepals. Stamens 5, slightly shorter than the petals, filaments white, anthers 

 red. Scales small, white, cuneate. Carpels white or reddish, compressed, 

 glandular-hairy or smooth, equalling the stamens, at first erect, wide-spreading 

 in fruit. 



Flowers July. Hardy. 



Habitat. — Europe, N. Africa, Canaries. 



Rarely seen in cultivation. My specimens came from Wisley, 

 where they were raised from seed supplied by M. Correvon (as 5. 

 littoreum) . 



In the rock-garden at Wisley a curious plant sows itself annually, 

 which has all the characters of S. rubens except that the flowers have 

 usually six petals and twelve stamens. In these characters it agrees 

 with S. hispanicum ; but its stouter, more woody stems, stouter 

 carpels not patent in fruit, and shorter styles, as well as its general 

 appearance, belong to S. rubens. It may possibly be hybrid, and 

 its carpels and styles sometimes vary towards hispanicum ; but on 

 the whole its characters are those of a hexapetalous dodecandrous 

 S. rubens.

A tiny yellow-flowered annual of no horticultural value, 

 recognizable by its much-branched habit. 



Description. — A small, much-branched annual (sometimes biennial). Stem 

 smooth, round, greyish, much branched, the branches bifid or trifid half-way up 

 or more, i to 3 inches long, with a flower in the forks. Flowers many, small, 

 yellow, borne laxly along the branches. Buds ovate, blimt. Leaves oblong- 

 linear, \ inch long, alternate, smooth, blunt, sessile, slightly spurred, pale green, 

 in section elliptic, straight or recurved, crowded on the young shoots, distant on 

 flowering shoots. Sepals resembling the leaves, oblong-lanceolate, very fleshy, 

 very blunt, unequal, not spurred, fused in the lower half. Petals broadly lanceo- 

 late or oblanceolate, acute, yellow, twice the sepals. Stamens yellow, wide- 

 spreading, | the petals. Scales oblong, greenish. Carpels at first erect, soon 

 spreading, equalUng the stamens, greenish yellow, in fruit stellate and surrounded 

 by the persistent, fleshy sepals. 



Flowers June-July. Hardy. 



Habitat. — Europe, Asia Minor, Greenland.
