__A straggling briar six or seven feet high. The 
branches bright green, reddish brown on the sunny 
side; armed with strong, scattered, hooked, nearly 
equal prickles (rarely straight, and then much closer 
together) and no sete. Leaves distant, pale or dark 
green, frequently tinged with red, in exposed situations 
usually much blistered by the sun, quite free from 
pubescence; stipules rather dilated, a little reflexed, 
acute-pointed; petiole armed with a few, little, hooked 
prickles; leaflets 5-7, ovate or oblong, acute or round- 
ed, sessile or subsessile, flat or concave, even or rugose, 
coarsely or finely, simply or doubly serrated, the ser- 
ratures always acute, without glands, and converging. 
Cymes one or many flowered; bractew ovate-lanceolate, 
appressed, acute, concave or flattish, finely toothed 
and glandular at the edge; peduncles and calyx smooth; 
tube ovate; sepals spreading, sharp-pointed, deciduous, 
somewhat divided; petals obcordate, concave; disk 
very thick, elevated; ovaries 20-30; styles nearly 
smooth, distinct, included or a little exserted. Fruit 
ovate or oblong, scarlet, shining, without any bloom ; 
pericarps large, uneven. |
