Shrubs or trees, 1-12 m tall; branches flattened to subterete, glabrous. Petiole 5-18 mm, glabrous; leaf blade drying papery or thinly leathery, oblong-elliptic, oblong-lanceolate, or lanceolate, 4.5-18.5 × 2-8 cm, both surfaces glabrous, base cuneate to obtuse or shortly rounded, sometimes inequilateral, apex acute to acuminate; secondary veins 3-7 pairs, in abaxial axils usually with foveolate and/or pilosulous domatia; stipules deciduous or sometimes persistent on distalmost nodes, broadly triangular, 3-8 mm, glabrous, apex acute or acuminate. Inflorescences fasciculate or shortly congested-monochasial and subsessile, 2-3 × 3-5 cm, several flowered, glabrescent; bracts ovate, often fused in pairs, 0.5-1 mm, acute to obtuse; pedicels 5-17 mm. Calyx densely to sparsely strigillose; ovary portion obconic, 1-1.5 mm; limb with basal tubular portion 3-5 mm; lobes 5, triangular to deltoid, 0.5-2 mm, acute. Corolla white or yellowish white, glabrous outside; tube 8-9 mm; lobes 5, narrowly spatulate-oblong, 4-7 mm, acute. Berry 5-8 mm in diam., sparsely strigillose or glabrous; seeds 6 or 7, flattened, angled, 2-3 mm. Fl. Apr-Jun, fr. May-Feb.
Thickets or forests on hills, on mountain slopes, or at streamsides in valleys; below 100-1500 m. Fujian, Guangdong, Guangxi, Hainan, Taiwan, Yunnan [Japan, Vietnam].
This species was excluded from Aidia and treated as Fagerlindia canthioides by Ridsdale (Blumea 41: 176. 1996), then as Benkara canthioides by Ridsdale (Reinwardtia 12: 289. 2008). This species is here included in Aidia because of its apparent lack of lateral short shoots or spines, inflorescences not terminal on developed stems, and apparently bisexual flowers.This species was excluded from Aidia and treated as Fagerlindia canthioides by Ridsdale (Blumea 41: 176. 1996), then as Benkara canthioides by Ridsdale (Reinwardtia 12: 289. 2008).
