Rosaceae, E. J. Mendes. Flora Zambesiaca 4. 1978

Morphology General Habit
Robust scrambling shrub up to 6 m. tall, with very stout canes.
Morphology Branches
Flowering branches straight or zig-zag, reddish-brown, somewhat villous, densely covered with stiff, straight, reddish bristles up to 5 mm. long; prickles 3–5 mm. long, straight or weakly decurved, glossy.
Morphology Leaves
Leaves 10–19 x 7–13 cm., temate; petiole and rhachis bristly like the stem, bearing smaller but more strongly hooked prickles; lateral leaflets subsessile, terminal one with petiolule 2·5–4 cm. long.
Morphology Leaves Leaflets
Leaflets broadly elliptic to obovate, markedly obtuse, sometimes apiculate, the terminal one larger than the laterals; margins minutely serrate; superior surface dark greyish-green, glabrescent; inferior surface pale greenish-grey, very shortly tomentose, with prominent veins, the midrib bristly and prickly.
Morphology Leaves Stipules
Stipules stiffly filiform.
Morphology Reproductive morphology Inflorescences
Inflorescences terminal and axillary, shorter than leaves; peduncles and pedicels villous and bristly, longer than bracts and bracteoles.
Morphology Reproductive morphology Flowers Calyx
Calyx rather leathery, dorsally bristly near the base, divided into broadly ovate lobes 5–7 mm. long.
