ACCOUNT OF GENUS SEDUM AS FOUND IN CULTIVATION. 55 



spreading, twice the sepals ; scales conspicuous, quadrate, more or less retuse 

 carpels nearly equalling the petals, slender, erect, slightly divergent above. 

 Female flower : — sepals long-triangular to oblong, blunt, tube short ; petals 

 linear, blunt, i^ times the sepals ; scales § the sepals, strap-shaped, emarginate, 

 reflexed ; carpels very erect, slightly longer than the petals. 



Flowers May-June. Hardy. 



Habitat. — Himalayan region ; western Yunnan. 



The flowers vary in colour. My .male plant is a white-flowered 

 form — sepals dark purple with a green tube, petals and filaments 

 white, anthers purple, scales orange, carpels green — a very bright 

 Uttle flower. Dried specimens at Kew appear to have the same 

 coloration, but purple throughout the flower seems to be more 

 usual. My female plant has flowers of a deep red-purple, the 

 carpels and scales of a deeper tint than the petals, the sepals green. 

 Plants collected in Yunnan by Forrest had pale lemon-yellow flowers, 

 others greenish. 



Not recorded as in cultivation. The male plant came to me from 

 Lissadell nursery as S. quadrifidum, where it was raised from Darjeeling 

 seed. The female was sent to Kew from Hexham-on-Tyne, where 

 it grows in a school garden, and is supposed to have been found wild 

 in Cornwall or Scotland !
