green or whitish, dotted red below on the inner face, at first erect, later slightly 
spreading, tapering into the slender short styles, equalling the stamens. 
Flowers late June. Hardy. 
Habitat. — Caucasus region. 
One of the most constant points of difference between this species 
and its close ally 5. Alherti (at least so far as the plants which I 
have seen are concerned) is not mentioned by Kegel in describing 
the latter species, namely, that in Alherti the forked branches of the 
cyme bear no flowers (only leaves) between the flower which occupies 
the primary fork and that which occupies the secondary fork, while 
in gracile flowers are borne all the way from the primary fork to the 
end of the simple branches. 
Rare in cultivation. I received it from Kegel and Kesselring in 
Petrograd, and obtained it also at Kew (as glaciale) and Bremen.

S. Alherti Kegel in "Acta Horti Petropol.," 6, 299, 1880. 
A small plant closely resembling 5. gracile C. A. Meyer, from which 
it differs in its more creeping stem not clothed with old leaves and 
inflorescence of (mostly 3) semi-erect forked branches, devoid of 
flowers between the primary and secondary forks, whereas in S. 
gracile the branches (mostly 2) are unbranched and spread almost 
horizontally, or are recurved, and bear flowers throughout their length. 
Description. — A small, glabrous, evergreen perennial. Stems procumbent, 
creeping, much branched, terete, red, shining, bare below, branches ascending, very 
leafy. Flower-stem i ^ to 2 inches high, ascending, usually unbranched, with larger, 
less dense leaves. Leaves linear-oblong, blunt, up to inch long on the flower- 
stems, smaller on the barren shoots, flattish on face, rounded on back, red- 
dotted, tips minutely papillose, prolonged at base into a short blunt spur. In- 
florescence of (usually) 3 semi-erect, leafy, forked branches, with a flower in the 
primary and secondary forks, but no flowers, only leaves, on the branches between 
these points ; flowers 25-30 in all. Buds ovate, acute. Flowers subsessile, 
^ inch across. Sepals elliptic, rather acute, fleshy, green, resembling the leaves, 
free almost to the base. Petals broadly lanceolate, acute or acuminate, patent, 
thrice the sepals, white on face, often dotted red on back, with a greenish keel. 
Stamens shorter than petals, filaments white, anthers red-purple. Scales small, 
pale, reddish, cuneate, retuse or emarginate. Carpels pale green or whitish, 
dotted red near the base of the inner face, at first erect, later spreading, equalling 
the stamens, styles slender, short. 
Flowers June. Hardy. 
Habitat. — Eastern Turkestan. 
Keceived from Messrs. Kegel and Kesselring of Petrograd as 
5. gracile (they also sent true gracile). Plants obtained under the 
name S. Alherti from the same firm and a number of British gardens 
were all forms of 5. album. The plant illustrated in " Gartenflora " 
(tab. 1019, fig. 2) as S. Alherti is a totally different thing.
