sepals spreading above. Flowers bright yellow, f-inch across, pedicels very 
short, hairy. Sepals green, very fleshy, linear-lanceolate, usually glabrous, 
nearly erect, blunt, f the petals, separate nearly to the base. Petals broadly 
lanceolate, acuminate or apiculate, wide-spreading, golden yellow. Stamens 
slightly shorter than the petals, the epipetalous ones free to the base, filaments 
yellow, anthers orange. Scales small, quadrate, yellowish. Carpels slender, 
nearly erect, equalling the stamens, tapering into the styles, contracted at the 
base, wide-spreading in fruit. 
Flowers August. Hardy. 
Habitat. — Manchuria. 
The plant is very rare in cultivation. The name is common enough 
in lists, and I obtained plants from a large number of different sources, 
but all were wrongly named, being mostly Aizoon, kamtschaticum, or 
Ellacombianum. I found the true plant at last in the Botanic Garden 
at Hamburg, and have to thank Dr. C. H. Ostenfeld of Copenhagen 
for kindly obtaining for me roots from there while direct communi- 
cation was cut off owing to the war. Masters' remarks [loc. cit., 
p. 268) seem to indicate that the plant was less rare in gardens forty 
years ago. 
Named after Ilarion Sergiewitsch Selsky, Secretary of the 
Siberian branch of the Russian Geographical Society in Irkutsk.

Allied to Aizoon, Ellacombianum, kamtschaticum. The type has 
narrower leaves than any of these, but the var. diffusum closely re- 
sembles in leaf some of the hybridum forms. From Aizoon, Midden- 
dorfflanum is distinguished by its slenderer growth, narrower leaves 
bearing only a few teeth near the apex, smaller flowers, etc. The 
narrow leaves alone will distinguish it from the spathulate-leaved 
Ellacombianum. It differs from kamtschaticum in its unbranched 
stems, denser inflorescence and smaller flowers ; hybridum stands apart 
in its creeping habit, many barren shoots, Hnear sepals and fruit not 
spreading horizontally ; and floriferum differs in its branched stems 
and sepals linear or even broader above than below. 
As pointed out by Maximowicz (" Primitise Flor. Amurensis," 116), 
there are two forms : — (i) with stems erect, crowded, comparatively 
short, densely leafy, leaves toothed near the apex, inflorescence com- 
pact ; and (2) stems longer, decumbent, rooting at the base, leaves less 
crowded, very long, toothed from the middle up, inflorescence larger 
and more lax. As an additional character it may be added that the 
leaves of the second are usually broader than those of the first. 
Both these forms are in cultivation at Petrograd and in British 
gardens. Intermediates are rare, and the two differ so much in general 
appearance that it appears desirable to distinguish them. The original 
description of Maximowicz covers both plants ; Masters applied the
