Stems stout, erect, usually 1-1.5 m. high, round, usually dark-brown, armed usually with 
paired, large, straight prickles, which are somewhat flattened below, 6-12 mm. long; young 
shoots rarely slightly bristly; floral branches glabrous or nearly so, usually with smaller infra- 
stipular spines; stipules 1-2 cm. long, adnate to the petioles, dilated, especially the upper- 
most, mostly glabrous, strongly glandular-dentate on the margins, the free portion ovate, 
acute; petiole and rachis glandular-puberulent and sometimes slightly pubescent; petioles 
1 cm. long or less; leaflets 5—9, usually 7, rounded-ovate, rounded at the both ends or acute 
at the apex, double-serrate with glandular teeth, 1.5—-5 em. long, dark-green and glabrous 
above, paler and somewhat glandular-puberulent, but rarely slightly pubescent beneath on the 
veins; flowers most commonly solitary, rarely 2-4 together; pedicels 2—3 cm. long, usually 
somewhat glandular-hispid; hypanthium glabrous; sepals lanceolate, caudate-acuminate, en- 
tire, often with foliaceous appendages at the apex, villous and glandular-ciliate on the mar- 
gins, glabrous or rarely glandular on the back, tomentose within, 2-3 cm. long; petals rose- 
colored, rarely white, broadly obcordate, 2.5—3.5 cm. long; styles not exserted; hypanthium in
