Solori microphylla (Miq.) Sirich. & Adema

         Deciduous trees 5–20 m high, dbh up to 25 cm. Bark pale grayish-brown. Twigs ca. 4 mm diam., lenticellate, velutinous. Stipules narrowly triangular, 4–5 by 0.5–0.7 mm, both sides sericeous, hairs shorter towards the base. Leaves with 19–41 leaflets, golden-brownish-green when young; petiole 9–17 mm long, grooved above, pubescent; rachis 5–15 cm long, grooved above, pubescent; pulvinus up to 5 mm long. Stipellae acicular, 0.4–0.7 mm long, sericeous. Leaflets chartaceous, terminal one (narrowly) elliptic to obovate, 14–30 by 7–9 mm, length/width ratio 2.1–3.3, base cuneate to broadly cuneate, apex rounded, emarginate, upper and lower surface thinly sericeous, midrib slightly sunken above, veins flat above, slightly raised below, 5–8 per side, 1–5 mm apart, becoming hardly visible near the margin, venation reticulate; lateral ones mostly like terminal one, (narrowly) elliptic, 7–29 by 4–8 mm, length/width ratio 1.6–3.7; pulvinus 1–2 mm long. Inflorescences axillary pseudoracemes, 8.5–16.5 cm long; peduncle 1.5–5 cm long, pubescent. Bracts subtending brachyblasts narrowly triangular to acicular, 2.2–2.5 by 0.3–0.4 mm, both sides sericeous, hairs shorter and more dense in lower part; bracts subtending flowers narrowly ovate to acicular, 0.7–1 by 0.2–0.3 mm, outside sericeous, inside glabrous or with some hairs. Brachyblasts knob-like or shortly cylindrical, more or less curved upwards, 1–3mm long, with 5–8 flowers. Pedicels 1–3 mm long, sericeous. Bracteoles at the base of the calyx, narrowly ovate, 0.6–0.8 by ca. 0.3 mm, outside sericeous, inside glabrous. Calyx brownish-green, cup-shaped, ca. 2.5 mm high, tube 1.5–2 mm high; upper lip with 2 short lobes, shallowly notched, 0.5–1 by 2–2.5 mm; lateral lobes triangular, 0.5–1 by 1–1.5 mm; lower lobe triangular, 0.5–1 by ca. 1.5 mm, outside sericeous, inside glabrous. Corolla purplish. Standard: claw 1.5–1.7 mm long; blade broadly obovate to orbicular, 7–7.7 by 5.5–6 mm, apex emarginate, with 2 small basal callosities, outside with some hairs at the apex and along the upper part of the midrib or glabrescent, inside with some hairs at the apex. Wings: claw ca. 2 mm long; blade elliptic, 6.5–7 by 2–2.5 mm, apex slightly curved upward, apex rounded, auricles and lateral pocket indistinct, both sides glabrous. Keel petals: claw ca. 2.5 mm long; blade more or less boat-shaped, 6–6.5 by ca. 3 mm, apex rounded, lateral pocket 1–2 mm long, outside with some hairs to thinly sericeous on major veins at ventral side and apex, inside glabrous. Stamens monadelphous, with basal fenestrae, 8–8.5 mm long, free for 2–3.5 mm, glabrous; anthers ca. 0.4 by 0.2 mm, glabrous. Disc tubular, ca. 0.3 mm high. Ovary 5–6 mm long, sericeous, stipe 0.5–1 mm long; ovules 11 or 12; style 2–3.5 mm long, sericeous at base. Pods more or less falcate, flattened, bulging over the seeds, 3.5–7 by 1.3–1.8 cm, stipe 2–3 mm long, upper wing 2–4 mm wide, outside thinly sericeous, glabrescent, seed chamber visible from outside, dark, veined. Seeds bean-shaped to transverse-ellipsoid, 4.5–7.5 by 3–5 mm; hilum central, ca. 1 mm long.
