A perennial plant, 0.5-2 m high. Stems ascending or not distinct, branched in upper part or many branches coming from the basal parts of stem and underground parts. Branches terete, ascending, sometimes spreading, when young slightly angular with densely ascending appressed-sericeous or spreading hairs (hairs 0.2-0.3 mm long, whitish), later glabrescent; distal parts die in winter season, proximal parts (and stem) with axillary and adventitious winter buds.

Leaves trifoliolate, petiolate, stipulate, spirally arranged. Stipules free, linear-triangular to linear, 2-7 mm long, brownish, persistent. Petioles 1-5 cm long, hairy like the young branch. Rachides 5-15 mm long, similar to the petiole. Terminal leaflets (at middle parts of branches) petiolulate; petiolules 1-3 mm long, swollen; lamina 2-6 cm long, 1.5-3.5 cm wide, entire, elliptic to ovate, round at the base, acute or obtuse at the apex (the apex itself with or without a point), upper surface glabrous or pubescent, lower surface appressed-sericeous (hairs 0.2-0.3 mm long); lateral ones similar to terminal but somewhat smaller.

Inflorescence axillary racemous, one (rarely 2-3) per axil, 2-15 cm long including the peduncle, loosely or compactly 4-14-flowered; peduncles 1-2 cm long, hairy like the young branch. Primary bracts ovate, about 1 mm long, pubescent, persistent; secondary bracts similar to primary ones.

Flowers 10-15 mm long at anthesis; pedicels 1-3 mm long, terete, curved, tomen-tose. Bracteoles at the base of the calyx broadly to narrowly ovate or obtuse, ca. 1 mm long, pubescent outside, glabrous inside, persistent. Calyx 3.5-6 mm long, cannpanu-late, four-lobed above or near the middle part, appressed pubescent; lateral one triangular with acute apex; upper one slightly two-clefted.

Standard nearly equal to, longer or shorter than keel-petal, keel-petal longer than wings. Standard red-purple inside, paler outside, 9.5-13.5 mm long with distinct claw; lamina (broadly to narrowly) elliptic, round or retuse at the apex with or without a point, inflexed-auriculate near the base, reflexing in anthesis from the part near the base; claw whitish. Wings deeper red-purple than standard, 8.5-10.5 mm long with distinct claw; lamina narrowly (to broadly) obovate to oblong, auriculate at upper basal part, slightly auriculate or tapering at the lower basal part; claw whitish. Keel-petal 10.5-13.5 mm long with distinct claw; lamina narrowly obovate, paler than wings, deepest in the apical part; claw whitish.

Ovary elliptic, ca. 1.5 mm long at anthesis, pubescent, stalked; stalk ca. 1.5 mm long.

Fruits compressed (broadly) elliptic, 7-12 mm long, 4-5 mm wide, densely to slightly pubescent (or nearly glabrous), stalked; stalk 1.5-2 mm long.

Our previous paper deals with this species (Akiyama & Ohba, 1988). This species has the widest range in sect. Macrolespedeza (Japan to E. Himalayas through Korea, Taiwan, and China) and shows remarkable geographical variation in the shape of calyx-lobes, and in the relative length of corolla to calyx and calyx-lobe to calyx-tube. Three subspecies are recognized: subsp, formosa from S.E. China, Hong Kong, Macao, and Taiwan; subsp. elliptica from S.W. China and Assam; and subsp. velutina from Japan, Korea, and E. China.

A perennial plant, 1.5-2 m high. Stems ascending, 0.5-1 m high, 1-3 cm in diameter; most of the terrestrial part lives only a few years; branched in upper parts (a few branches coming from the basal part of the stem). Branches terete, ascending, sometimes dependent later; when young slightly angular with densely ascending appressed-sericeous hairs (hairs 0.2-0.3 mm long, whitish), later glabrescent; distal parts die in winter, proximal parts (and stem) with axillary and adventitious winter buds (winter buds at lower parts mostly dormant).

Bracteoles at the base of the calyx broadly to narrowly ovate or obtuse, ca. 1 mm long, pubescent outside, glabrous inside, persistent. Calyx 3.9-4.4 mm long, campanulate, four-lobed above the middle part, appressed pubescent; tube 1.6-1.7 mm long; the lower lobe longest; lateral ones 2.2-2.7 mm long, 0.8-1.1 mm wide, triangular-lanceolate, acute at the apex but not acuminate; upper ones slightly two-clefted.

Standard nearly equal to keel-petal, keel-petal longer than wings (S≥K>W). Standard red-purple inside, paler outside, 10.7-12.4 mm long with distinct claw, 6.0-7.2 mm wide; lamina (broadly to narrowly) elliptic to obovate, round or retuse at the apex with or without a point, inflexed-auriculate near the base, reflexing in anthesis from the part near the base; claw whitish, 2.0-2.4 mm long. Wings deeper red-purple than standard, 8.6-10.1 mm long with distinct claw: lamina narrowly obovate to oblong, 6.0-7.3 mm long, 2.0-3.2 mm wide, auriculate at upper basal part, slightly auriculate or tapering at the lower basal part; claw 2.9-3.4 mm long, whitish. Keel-petal 10.5-12.0mm long with distinct claw; lamina narrowly obovate, 7.4-8.6 mm long, 3.2-3.7 mm wide, paler than wings, deepest in the apical part; claw 3.1-3.6 mm long, whitish. Stamens 10, nearly the same length, 10-11.5 mm long, diadel-phous. Anthers elliptic, shallowly retuse at the apex, ca. 0.6 mm long; before anthesis yellow. Pistils 11.5-12 mm long; ovary elliptic, ca. 1.5 mm long at anthesis, pubescent, stalked; stalk ca. 1.5 mm long; style 7-8.5 mm long, pubescent at the basal part, glabrescent at the apical part.

Fruits compressed (broadly) elliptic, 7-8(-9) mm long, 4-5 mm wide, densely to slightly pubescent (or nearly glabrous), stalked; stalk 1.5-2 mm long.

Seeds reniform, 3-3.5 mm long, 2-2.5 mm wide.

KANGWON. Jangjun (Chozen) (Nakai 5576, TI-Holotype of L. intermedia var. alba Nakai).

For the white-flowered Lespedeza, many names have been described under different species as varieties or forms, although most are cultivated plants. In this paper we treat cultivated white-flowered Lespedeza as different species. Native white-flowered form of this species is known from Korea only and described by Nakai as the variety of L. intermedia (non Britt.) Nakai. The specimen of white-flowered Lespedeza (Kuro-kawa TI) has a label on which it is written that this plant is wild (Maekawa, 1938). It is doubtful whether this plant is truly wild or naturalized.
