2. R. brevispinosum, 0. Aunize in Jahrb. Bot. Gart. Berlin, iv. 
270. An erect, slightly branched, spiny shrub, 4-10 ft. high. Branches 
Virgate, quadrangular, tomentose or pubescent in a young state, finally 
becoming glabrous; spines developed into leafy branches. Leaves 
usually all simple (occasionally both simple and trifoliolate), alternate 
on the young shoots, on older shoots fascicled 3-10 together on tomen- 
tose cushions, sessile or subsessile (the trifoliolate leaves with petiole 
1-1} lin. long), oblong-oblanceolate or linear-oblanceolate, rounded, 
retuse or emarginate at the apex, tapered towards the base, 4—18 lin. 
long, 1-44 lin. broad, more or less densely tomentose in a young state, 
mature leaves tomentose or puberulous, rarely glabrous. Flowers 
Solitary or fascicled on the leaf-cushions. Calyx cam panulate, 23-4 
lin, long, more or less irregularly 5-lobed, tomentose outside, sometimes 
glandular in the upper part; tube 13-3 lin. long ; lobes 3-1 lin. long, 
rounded, mucronate or not. Corolla yellow or white; tube campanu- 
late-funnel-shaped, 54-9 lin. long, minutely glandular-pilose at the 
throat and below the insertion of the stamens ; basal cylindric portion 
1}-3 lin. long; lobes suborbicular, retuse or emarginate, 5-9 lin, in 
diam., ciliate. Stamens exserted trom the corolla-tube, inserted 2-6 
lin. above its base ; filaments 14-44 lin. long; anthers 14-24 lin. long 
or less, not apiculate. Ovary 1-1} lin. long. Capsule oblong or 
elliptic-oblong, 2-3 in. long, 6 lin. broad, beak about 3 lin. long.
