late summer from near the base of the flowering stems, remaining short and leafy 
throughout the winter, shooting up, flowering, and dying in the following season ; 
ascending, 6-9 inches long, round, unbranched at first, but producing axillary 
flowering branches when the main stem has flowered. Leaves alternate or 
opposite, sessile, to 2 inches long, obovate to spathulate, toothed in upper 
third, entire and tapering in lower two-thirds, dark green, shining, margin 
minutely papillose. Inflorescence of lax terminal umbellate cymes, bracts small, 
lanceolate, entire. Buds ovoid, acute, with orange ribs. Flowers orange-yellow, 
I inch across. Sepals green, broad below, narrowed half way up to a linear blunt 
end. Petals orange-yellow, lanceolate, apiculate, keeled, twice the sepals or 
rather more. Stamens nearly as long as the petals, filaments yellow, anthers 
orange. Scales whitish, broader than long. Carpels yellow, slightly exceeding 
the stamens, erect in flower, wide-spreading in fruit, changing as the flower fades 
through orange and crimson to brown. 
Flowers June to September. Hardy. 
Habitat. — North-eastern Asia, as far south as Corea and Central 
China. 
Common in cultivation, and generally correctly named. Much 
more constant in character than most of the section, and little excuse 
exists for its sale under such names as Brownii, Braunii, Lehmanni, 
lividum, Maximowiczii, pallidum, and portulacoides. Its name kam- 
tschaiicum commemorates the region from which it was first described. 
f. variegatum. 
With a broad irregular marginal band of white on the leaves. A 
handsome rock-garden plant, the variegated foliage combined with 
the orange flowers producing a showy effect.

Allied to 5. kamtschaticum and 5. hybridum, and in many respects 
intermediate. It shows close affinity to the latter in its sepals, which 
are linear or oblanceolate, not wide at the base as in most of the 
section, and in the size and appearance of its flowers ; its leaves also 
are nearest to those of hybridum. But instead of being evergreen with 
perennial creeping stems as in that species, it has the growth-form 
of kamtschaticum, the stems arising in autumn, remaining short during 
the winter (fig. 63, a), and flowering and dying in the following 
season ; the carpels also are those of kamtschaticum, though 
one- third smaller, as in hybridum. From both hybridum and 
kamtschaticum it differs in the tendency of its stems to produce many 
short axillary floriferous branches, which give the plant a bushy and 
very distinct appearance. 
Description. — A glabrous sub-evergreen perennial. Rootstock woody, 
knotted, roots thickened. Stems many, annual, arising in autumn, ascending 
or decumbent, red, somewhat scabrid, about 6 inches long, leafy, branched in 
upper half or two-thirds, branches axillary, leafy, short, wide-spreading, often 
numerous, bearing cymes similar to the terminal one. Leaves sessile, spathulate- 
oblanceolate, dark green, up to i J inch long by f broad, tapered and entire below, 
toothed in upper third, crowded, blunt ; those of the branches similar but much 
smaller. Inflorescence of terminal and lateral flattish, rather dense cymes 
1-2 inches across, each usually of three forked branches with flowers in the
