Two or three feet high, compact, reddish gray. 
Branches not much divided, erect, with very strong, 
dense, unequal, straight prickles and sete and a cracked 
tk. Leaves close together with a slight turpentine 
smell when bruised; stipule narrow, somewhat con- 
cave, acute, naked, but toothletted and fringed with 
glands; petioles hairy, glandular and setigerous, a few 
straight longer prickles being interspersed ; leaflets 5-7, 
concave, ovate, acute or obtuse, doubly serrated, naked 
above or nearly so and opaque, villous beneath with a 
few pale glands, scarcely distinguishable from the sur- 
Flowers solitary, without bractez, red and 
white ; peduncle, spherical tube of the calyx and simple 
sepals bristly all over with pungent setee and clammy 
glands; petals obcordate, involute; disk a very little 
elevated; unripe fruit crowned by the converging 
sepals.

in a dried state. When growing, their appearance is:
