gardens it commences to bloom in September, three weeks before the 

 well-known 5. Sieholdii. 



Named from its growing on cliffs.

A handsome Japanese member of the Telephium group, first 

 described from English specimens cultivated as long ago as 1839. 

 Its arching habit, roundish sessile glaucous leaves in threes, and 

 rosy-purple flowers, distinguish it from any other species. It is the 

 last to flower of all the Old World Sedums. 



Description. — A glaucous herbaceous perennial. Root a tuft of small 

 carrot-like tubers. Stems many, unbranched, 6-9 inches long, low-arching, 

 smooth, round, red. Leaves temate, sessile or subsessile, nearly orbicular, 

 slightly cuneate below, fleshy, flat or concave, glaucous, sometimes flushed red, 

 margin sinuate or bluntly toothed in upper half, red. Inflorescence a compact 

 terminal flattish umbellate cyme about 2 inches across, with many small ovate 

 bracts ; pedicels enlarged upwards, about as long as the flowers. Flowers 

 nearly \ inch across, pink. Buds obovoid, purplish, with red markings and 

 greenish ribs. Sepals deltoid, acute, dark green, separate nearly to the base. 

 Petals thrice the sepals, pink, broadly lanceolate, acute, spreading, minutely 

 hooded at the tip. Stamens spreading, the epipetalous ones equalling the petals, 

 the others slightly longer, filaments pink, anthers purple. Scales oblong, trun- 

 cate, curving upwards, flushed orange except when young, entire or slightly 

 emarginate. Carpels short, broad, erect, pink with linear markings of a deeper 

 tint, abruptly narrowed below into a distinct white stalk, styles short. 



Flowers October. Hardy. 



Habitat. — J apan. 



It is hardy, but is most frequently seen as a greenhouse or cottage- 

 window plant. Slugs are fond of it. Its nearest ally is S. cauiicolum, 

 which differs in its opposite stalked leaves, leafy inflorescence of 

 darker flowers, and other minuter characters. Named in honour 

 of P. F. VON SiEBOLD (1796-1866), author of valuable works on the 

 flora of Japan. 



f. foliis medio-variegatis. 



A form with a large splash of yellow occupying the middle of 

 the leaf. A favourite pot-plant. A good coloured plate will be found 

 in " Illustration Horticole," tab. 373.

A pretty species, with fleshy leaves of a distinctive shape — narrowly 

 lanceolate with large teeth — and terminal clusters of pinkish flowers.
