Solori robusta (Roxb. ex DC.) Sirich. & Adema

         Deciduous trees, 9–20 m high, dbh 20–25 cm. Bark smooth, pale grayish-brown. Twigs terete, 1–5 mm diam., strigose. Stipules acicular, 4–5.5 by 0.3–0.5 mm, sericeous. Leaves with 11–19 leaflets; petiole 2.5–3 cm long, striate, grooved above, sericeous; rachis 10–13 cm long, striate, grooved above, sericeous; pulvinus 3–7 mm long. Stipellae acicular, 0.7–2.5 mm long, sericeous. Leaflets subcoriaceous; terminal one elliptic, 2.6–6 by 1–2.5 cm, length/width ratio ca. 2.5, base cuneate, apex acute, mucronate, upper surface thinly sericeous or nearly glabrescent, lower surface sericeous, midrib and veins slightly raised or flat above, raised below, veins 4–6 per side, 3.5–7 mm apart, curving towards the apex, anastomosing near or sometimes at the margin, venation reticulate; lateral onesmostly as terminal one, ovate to elliptic, 1.4–6.5 by 1–1.7 cm, usually oblique, basiscopic side narrower; pulvinus 2–3 mm long. Inflorescences axillary pseudoracemes, 5.5–27.5 cm long, peduncle 2–5.5 cm long, sericeous. Bracts subtending brachyblasts narrowly ovate, ca. 0.5 by 1–2.2 mm, outside sericeous, inside glabrous, sometimes caduceus; bracts subtending flowers elliptic, 0.7–0.8 by 0.3–0.4 mm, caducous, outside sericeous, inside glabrous. Brachyblasts slender 2–3.5 mm long, 3–7-flowered, if 3-flowered, then all flowers usually at the apex of the brachyblast, if more than 3 flowers or if the brachyblasts short, then the flowers seemingly more scattered. Pedicels 3–4.5 mm long. Bracteoles at the base of the calyx, elliptic, 0.6–0.7 by ca. 0.3 mm, outside sericeous, inside glabrous. Calyx 2.5–3 mm high, outside sericeous, inside glabrous, tube 2–2.5 mm high; upper lobes triangular, 0.5–0.7 by 2–2.5 mm; lateral lobes triangular, 0.5–0.7 by 1.5–1.7 mm; lower lobe triangular, ca. 0.5 by 1.5–1.7 mm. Corolla white. Standard: claw 1.5–2 mm long; blade orbicular, 6–7.5 by 5.5–5.7 mm, apex emarginate, basal callosities small or indistinct, both sides sericeous at apex. Wings: claw 2–2.5 mm long; blade elliptic, 5–5.5 by 1.5–1.7 mm, apex rounded, lateral pocket up to 1 mm long, sometimes hardly visible, auricle indistinct, both sides glabrous or with few hairs at apex. Keel petals: claw 2–3 mm long; blade boat-shaped, 5–6.5 by 2–2.5 mm, apex rounded, lateral pocket 1–1.5 mm long, glabrous or with few hairs at apex. Stamens monadelphous, with basal fenestrae, 7–8 mm long, free for ca. 2 mm, glabrous; anther 0.3–0.4 mm long, glabrous. Disc tubular, 0.3–0.4mm high. Ovary ca. 5 mm long, stipe ca. 0.5 mm long, sericeous; ovules 7–11; style 2–2.5 mm long, glabrous and slightly sericeous at base. Pods strap-like, 1.5–8.5 by 0.7–1.1 mm, flat, sericeous, 4–8 seeds per pod, with a wing along the upper suture, ca. 2 mm wide; seed chamber slightly solid, visible from outside. Seeds ellipsoid, 4–4.5 by 3–5 by 0.6–1.5 mm; hilum central, 0.4–0.5 mm long.
