Rubus subgen. Dalibardastrum Focke, Biblioth. Bot. 17(Heft 72): 39. 1910.

Shrubs or subshrubs, usually densely bristly, less often with needle-like or small prickles. Leaves simple; stipules persistent or caducous, free, on stem near base of petiole, broad, divided. Flowers bisexual, usually in cymose panicles or short subracemes or several in clusters or solitary. Aggregate fruit adnate to torus, falling from base of torus at maturity, not hollow.

Eleven species (ten endemic) in China.

+ Terminal inflorescences subracemes with few flowers or flowers several in clusters or solitary.   (4)
2 (1) Leaves glabrous abaxially, ovate-lanceolate or elliptic-lanceolate, not divided; flowers with petals.   185 R. wuzhianus
+ Leaves tomentose or pubescent abaxially, narrowly ovate or suborbicular; flowers with or without petals.   (3)
3 (2) Leaves narrowly ovate, abaxially tomentose, margin undivided or slightly undulate; flowers usually apetalous.   183 R. jinfoshanensis

4 (1) Leaves abaxially tomentose.   (5)
+ Leaves abaxially pubescent or subglabrous.   (7)
5 (4) Leaves 3–5-lobed, suborbicular or broadly ovate, deciduously tomentose, but hairs persistent abaxially in age; stipules broader, 1–1.5 cm, palmately parted.   188 R. tsangiorum

6 (5) Leaves ovate to oblong, bristly on both surfaces, not divided or somewhat undulate, coarsely sharply serrate; stipules tomentose, villous; flowers 2–3 cm in diam.   186 R. tricolor
+ Leaves suborbicular to ovate, bristly only abaxially, margin 3–5-lobed, sharply serrulate; stipules tomentose; flowers 1–2 cm in diam.   187 R. multisetosus
7 (4) Flowers solitary or in clusters of 2–4, terminal or axillary; leaves broadly ovate, undivided, rarely lobed;outer sepals usually not lobed.   (8)
+ Flowers 4–12 in terminal subracemes or several in clusters; leaves suborbicular or broadly narrowly ovate, lobed; outer sepals usually divided.   (9)
8 (7) Plants with stalked glands; leaves acute to acuminate apically, both surfaces glabrous or nearly so; pedicel 2–4 cm; sepals triangular-lanceolate, 0.8–1.4 cm.   192 R. ourosepalus
+ Plants without stalked glands; leaves obtuse, rarely acute apically, both surfaces sparsely villous; pedicel 5–10 mm; sepals broadly ovate, 7–8 mm.   193 R. polyodontus
9 (7) Leaves broadly narrowly ovate, terminal lobe several × as long as lateral lobes, apically shortly acuminate, rarely acute, lateral lobes obtuse; flowers 1–1.5 cm in diam.; stipules deeply laciniate; sepals narrowly lanceolate; outer sepals 2- or 3-laciniate.   191 R. amphidasys
+ Leaves orbicular or suborbicular, terminal lobe slightly longer than or as long as lateral lobes, acute, obtuse, or rounded; flowers 1.5–2(–2.5) cm in diam.; stipules palmately parted to middle or nearly to base; sepals narrowly ovate, narrowly ovate-lanceolate, or broadly ovate-lanceolate to oblong-ovate; outer sepals leaflike, laciniate, pinnately divided, or dissected apically.   (10)
10 (9) Leaves 3–5-lobed, terminal lobe acute apically, lateral lobes obtuse, rarely acute, margin coarsely serrate; stipules palmately parted nearly to base; sepals narrowly ovate or narrowly ovate-lanceolate; outer sepals leaflike, laciniate or pinnately divided.   189 R. treutleri
