Geum aleppicum

Roots fascicled, fibrous. Stems erect, 30-100 cm tall, together with petioles spreading rigid hairy, rarely glabrescent. Radical leaves lyrate-pinnate, 5-15 cm including petiole, usually with 2-6 pairs of leaflets, both surfaces sparsely rigid hairy; leaflets unequal, terminal one largest, broadly rhombic-ovate or compressed orbicular, 4-15 cm long, 5-15 cm wide, base broadly cordate to cuneate, margin usually irregularly coarsely serrate, apex obtuse or acute; cauline leaves: stipules green, leaflike, ovate, large, margin irregularly coarsely serrate; leaf blade pinnate, sometimes repeatedly lobed; terminal leaflet lanceolate or obovate-lanceolate, base cuneate, apex often acuminate or shortly so. Inflorescence terminal, lax. Flowers 1-1.7 cm in diameter; pedicel pubescent or hirtellous. Sepals ovate-triangular, apex acuminate; epicalyx segments lanceolate, minute, ca. 1/2 as long as sepals, abaxially pubescent and villous, apex acuminate, rarely 2-fid. Petals yellow, suborbicular, longer than sepals. Style terminal, twisted at joint ca. 1/4 way from apex; proximal section pilose; distal section deciduous at fruit maturity. Achene aggregate obovoid; fruiting receptacle hispidulous, hairs ca. 1 mm; achenes hirtellous; proximal section of style persistent, glabrous, apex hooked.

Geum aleppicum var. bipinnatum (Batalin) Handel-Mazzetti; G. intermedium Besser ex Marschall von Bieberstein (1808), not Ehrhart (1791), nor Willdenow (1806), nor Tenore ex Nyman (1878); G. potaninii Juzepczuk; G. strictum Aiton; G. strictum var. bipinnatum Batalin; G. vidalii Franchet & Savatier.

Geum aleppicum is close relative of Geum japonicum var. chinense, but differs from the latter in its receptacle hispidulous (vs. hirtellous), hairs ca. 1 mm (vs. 2-3 mm); cauline leaves 2-6-foliolate, sometimes repeatedly pinnatifid (vs. upper cauline leaves usually simple, entire or 3-lobed); terminal leaflet of radical leaves broadly rhombic-ovate or obovate-lanceolate (vs. ovate to broadly obovate), apex usually acuminate (vs. rounded).
