A taller bash than R. lucida with a more straggling 
habit. Branches red, either unarmed, or furnished 
with a few weak, pale, setiform prickles, now and then 
decreasing into sete; rootshoots very red, densely co- 
vered with very unequal, scattered, crimson prickles: 
of these the largest are compressed and falcate, as 
they decrease in size becoming gradually straighter till 
they change into setz. Leaves distant, tinged with 
red, which becomes darker in the autumn;  stipule 
naked, flat, waved, either narrow or much dilated, 
finely toothed ; petioles armed with a few short, straight 
prickles, glands being here and there intermixed ; 
leaflets 3-9, simply or doubly serrated, undulated, en- 
tirely free from pubescence. Cymes many-flowered, 
overtopped by the young shoots; dractee ovate lan- 
ceolate, with a point, naked, finely toothed, large and 
spreading ; flowerstalks rough with setz and glands: 
tube of the calyx cyathiform, at the bottom rough like 
the stalks; sepals compound, with a foliaceous end, 
longer than the petals, hispid without ; petals always 
multiplied, bright red, smaller than those of R. lucida ; 
disk nearly obliterated. Fruit deep red, crowned by 
the reflexed sepals, round, with a very wide mouth 
which is filled up by the densely villous styles.
