Species Information

Low to medium shrub, 0.3-1.5 m tall; stems spindly, erect to spreading, usually bristly with numerous soft, straight prickles all about the same size, occasionally unarmed especially on younger stems, which are often stalked-glandular; mature stems greyish-brown.
Alternate, deciduous, odd-pinnately compound, the leaf-stalk and axis somewhat stalked-glandular; leaflets 5, 7 or 9, elliptic, 1-4 cm long, double-toothed with gland-tipped teeth, otherwise smooth; stipules glandular and usually blunt-toothed.
Inflorescence of usually single, occasionally 2 to 3, stalked flowers at the ends of lateral branchlets, the stalks bristly-glandular; corollas pale pink to rose, bowl- to saucer-shaped, small (2-3.5 cm across), the petals 5, 10-15 mm long; calyces 5-lobed, the lobes 5-12 mm long, egg-shaped to triangular tapering to a tail-like sharp tip, smooth or occasionally glandular on the back, deciduous; ovaries superior but enclosed in the urn-shaped floral tube (hypanthium); stamens numerous.
Achenes, few to about 12, smooth except for a few long hairs at the tip, enclosed by the fleshy hypanthium, which ripens into an orange to scarlet, pear-shaped to ellipsoid hip 6-10 mm long, the neck and calyx-lobes deciduous.
