Opposite leaves. A study of the growing plant shows that it is certainly 
a form of verticillatum, with which it agrees in all points save its smaller 
size and the arrangement of its leaves ; the flowers, leaves, colour, and 
habit are those of verticillatum. Young and weak plants of S. verti- 
cillatum often have their leaves opposite, and in this dwarf form this 
immature character seems perpetuated. Doubtless a wild Japanese 
form, but so far known only from gardens in Japan and England.

A well-known species, long in cultivation, distinguished among the 
purple-flowered Sedums by its semi-trailing habit and opposite pairs 
of entire clasping leaves. Unlike most of the Telephium section, the 
new stems arise, not from buds at the base of the old stem, but from the 
lower part of the stems themselves, so that eventually a much-branched, 
low twiggy mass is formed, which is bare in winter. 
Description. — A glaucous herbaceous perennial, dying back in winter to a 
short spreading, much branched twiggy rootstock. Stems round, smooth, un- 
branched, the barren ones spreading, the flowering ones longer (6-12 inches) 
ascending or spreading. Leaves sub-opposite, entire or faintly toothed, fleshy, 
glaucous, sessile, about f inch long by | inch broad, those of the barren shoots 
and the lower ones of the flowering shoots orbicular to broadly ovate or obovate, 
rounded and not clasping at the base, longer than the internodes ; upper leaves 
of the flowering shoots cordate and clasping, shorter than the internodes. In- 
florescence a dense terminal umbellate cyme, 1-2 inches across, surface convex. 
Buds ovoid, bluntly pointed. Flowers purplish pink, nearly ^ inch across, as 
long as the pedicels. Sepals linear-lanceolate, separate nearly to the base, 
glaucous. Petals ovate-lanceolate, acute, purplish pink, more than twice the 
sepals, wide-spreading, the nerve on back green near the tip. Stamens shorter 
than the petals, filaments pink, anthers dark purple. Scales whitish or yellowish, 
oblong, notched. Carpels erect, pink, shorter than the stamens, erect in fruit. 
Flowers August-September. Hardy. 
Habitat. — Western Himalayas to the Altai, Soongar, and 
Mongolia. 
Var. homophyllum var. nov.* (fig. 46). 
Much smaller than the type. Stems 2-3 inches long, flowering ones but little 
longer than the barren ones ; shoots dying back less far in proportion during 
winter and producing many very short, small shoots below. Leaves of both

steriles parum superantes. Folia caulium sterilium et floriferorum integra,
