2. R. brevispinosum, 0. Kuntze 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, 

 refuse or emarginate at the apex, tapered towards the base, 4-18 lin. 

 long, 1— 4£ 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 campanulate, 2-|— 4 

 lin. long, more or less irregularly 5-lobed, tomentose outside, sometimes 

 glandular in the upper part ; tube 1^—3 lin. long ; lobes \— 1 lin. long, 

 rounded, mucronate or not. Corolla yellow or white ; tube campanu- 

 late-funnel-shaped, 5J-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, refuse or emarginate, 5-9 lin. in 

 diam., ciliate. Stamens exserted from the corolla-tube, inserted 2-G 

 lin. above its base ; filaments 1 \-±\ lin. long ; anthers 1-t- 2A- 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.
