Beilschmiedia kwangsiensis Kostermans, Reinwardtia 7: 453. 1969; Potameia kwangsiensis Kostermans.
Small to large trees, 8-23 m tall, 15-45 cm d.b.h. Bark gray. One-year-old branchlets yellow-brown, terete, striate, densely lenticellate, glabrous; current year branchlets red-brown, ± angled, striate, densely warty, glabrous. Terminal buds small, ovoid; bud scales densely rusty pubescent. Leaves alternate; petiole 1-1.5 cm, plano-convex, glabrous; leaf blade glaucous abaxially and yellow-brown adaxially when dry, elliptic to ovate-elliptic, 10-13 × 5-7 cm, papery when young but subleathery when mature, lateral veins ca. 6 pairs, basal lateral veins oblique, near leaf base and very developed, lateral veins and midrib conspicuously elevated abaxially, impressed adaxially, transverse veins and veinlets reticulate, ± conspicuous and shallowly foveolate on both surfaces when young, obscure abaxially and conspicuous adaxially when mature, base broadly cuneate to subrounded, subequal on sides, margin revolute and undulate, apex abruptly shortly acuminate, acumen obtuse and up to 2 cm. Panicle axillary, (2.5-)3-6.5 cm, usually solitary but always collaterally 2 or 3, few flowered, without floral leaves; peduncle red-brown, (1.5-)2-3 cm, ± compressed, glabrous, branches short, 1-1.5 cm; bracteoles subulate, minute, less than 1 mm, caducous. Pedicels slender, up to 3 mm, glabrous. Flowers yellow, small, ca. 2 × 2 mm. Perianth glabrous outside and inside; perianth tube obconical, ca. 1 mm; perianth lobes 4, broadly triangular-ovate, ca. 1 × 1 mm, obtuse. Fertile stamens 4, slightly exserted; filaments slightly longer than anthers, villous, outer 2 each with 2 glands; anthers broadly triangular, ca. 0.5 mm, acute, 2-celled; cells introrse. Staminodes 4, opposite to fertile stamens, linear, ca. 0.6 mm, glabrous, attenuate at apex. Stigma small, inconspicuous. Mature fruit globose, up to 5 cm in diam., red-brown when dry, smooth, glabrous, rounded and inconspicuously apiculate at apex; pericarp corky. Seed 1, globose. Fl. Apr, fr. Oct.
● Dense valley forests on hilly land; 300-700 m. SW Guangxi (Shiwan Dashan).
When Kostermans described Beilschmiedia kwangsiensis, he cited Tsang 22586 (BO) as the holotype. He later described Potameia kwangsiensis (Adansonia, sér. 2, 17: 92. 1977), citing Tsang 22586 (P) as the holotype. The present authors accept B. kwangsiensis and P. kwangsiensis as separate names because they have different holotypes (different specimens, although from the same gathering). Li, when making the new combination Syndiclis kwangsiensis, cited B. kwangsiensis as the basionym and treated P. kwangsiensis as a synonym.When Kostermans described Beilschmiedia kwangsiensis, he cited Tsang 22586 (BO) as the holotype.
