cephalanthum, Franch., also from south-western China. 
As is shown in our illustration, at fig. 8, the plant from 
which our figure was prepared has some of its filaments 
devoid of anthers; that this reduction may have been 
the result of cultivation is probable ; the presence of the 
tendency may nevertheless have some bearing on the 
taxonomic status of the group to which R. Sargentianum 
belongs. Being dwarf, compact and slow of growth, 
this species is admirably suited for cultivation in the 
Rock Garden, where it should be provided with a mixture 
of sandy loam and peat. It will probably thrive best in 
a nook shaded from the mid-day sun. Failing seed, it 
can be propagated by cuttings taken in July and placed 
in very sandy soil under a bell-glass in gentle heat. 
The plant now figured was presented to Kew by Mr. 
F. R. 8. Balfour of Dawyck, Peebleshire, in March, 1914. 
It flowers in May. 
Description.— Undershrub, reaching a height of 2 ft., much branched, the 
twigs erect or ascending, when young very short and loosely covered with 
soft scales, when older beset with persistent bud-scales, Leaves aromatic, 
wide elliptic, mucronate, sometimes slightly emarginate, base wide euneate 
passing into a stalk about ;; in. long which is lepidote on the back, 3-3 in. 
long, 3-} in. wide, coriaceous, at first loosely lepidote above, but soon glabrous 
and polished, below softly lepidote; midrib sunk above, raised and nearly 
glabrous beneath. Flowers loosely umbellately racemose, pale yellow; bud- 
scales somewhat persistent, wide obovate, long-ciliate, lepidote, about as long 
as the pedicels which are 1-1 in, long and covered with yellow scales. Calyx 
green, fairly large, lobes oblong, } in. long, rounded at the tip, long ciliate, 
loosely lepidote behind. Corolla hypocrateriform, lepidote outside except on 
the margins of the lobes; tube wide cylindric, over $ in. long, villous within ; 
lobes 5, spreading, nearly orbicular, 3-3 in. across. Stamens 5, included; 
oe usually antheriferous, occasionally sterile, about 3 in. long, glabrous. 
aed subglobose, 5-celled, yellow lepidote; style glabrous, shorter than the
