Flowers September-October. Hardy. 



Habitat. — Japan ; Central China (Diels) ; long cultivated in the 

 latter country, but till lately not certainly known there in the wild 

 state. 



The name spectabile refers to its notable appearance.

Easily recognized among the cultivated Sedums of the Telephium 

 section by its comparatively narrow-stalked leaves in whorls of 4 or 5 

 and its green flowers. 



Description. — A glabrous herbaceous perennial. Rootstock thick, with 

 fleshy spindle-shaped roots. Stents annual, erect, smooth, green, round, simple 

 or with a few axillary branches above, 1-2 feet high. Leaves whorl ed, the lower 

 ones often opposite or temate, the upper in whorls of 4 or 5, oblong-lanceolate, 

 narrowed at both ends, stalked, obscurely and bluntly toothed, smooth, green, 

 pale below, only slightly fleshy, minutely dotted purple, 2-3 inches long, 

 f-i inch broad, petiole J inch or more. Inflorescence corymbose, terminal, very 

 dense, roundish on surface, sparingly leafy, 2-3 inches across, pedicels slender, 

 equalling the flowers. Buds ovate, blunt. Flowers green, J inch across. Calyx 

 cup-shaped, green, fleshy, lobes deltoid-lanceolate, rather acute, tube very short. 

 Petals pale green, wide-spreading, ovate-lanceolate, acute, 4 times the sepals. 

 Stamens slightly exceeding the petals, the epipetalous ones adnate in the lower 

 third and shorter than the others, filaments pale green, anthers buff or pale red. 

 Scales nearly twice as long as broad, linear-cuneate, retuse, yellow. Carpels 

 stout, green, erect, equalling the petals, styles short. 



Flowers September. Hardy. 



Habitat. — Japan, Kamtschatka. 



Several of the East Asiatic species of the Telephium section have 

 leaves arranged in whorls of three to five, but the present is the only 

 one which appears to be in cultivation. I owe my plants to the kind- 

 ness of Professor Miyabe of Sapporo University Botanic Garden. My 

 plants, when young or when the inflorescence does not develop fully, 

 tend to produce in autumn numerous small axillary buds above, after 

 the manner of the nearly allied S. viviparum Maxim. 



Named from its whorled leaves.

A dwarf slender form of 5. verticillatum with opposite leaves grown 

 at Kew under the name 5. laiifolium (a synonym of S. maximum L.) is 

 clearly the plant which Maximowicz alludes to {loc. cit.) under 5. albo- 

 roseum and which he would have placed under verticillatum but for its
