Shrubs, 2-3 m tall; branches flattened to subterete, often rather slender, strigillose to strigose or pilosulous, sometimes with lateral short shoots to 0.5 cm; thorns slender to stout, 3-30 mm, straight, or sometimes absent. Leaves paired along developed stems or sometimes clustered on lateral short shoots; petiole 2-3 mm, strigillose to pilosulous; blade drying papery, ovate to lanceolate or elliptic, 2-6 × 1-3.5 cm, adaxially glabrous or strigillose to hispidulous along principal veins or throughout, abaxially puberulent to strigillose or hispidulous, base rounded or obtuse, apex obtuse, acute, or weakly acuminate; secondary veins 2 or 3 pairs, in abaxial axils with pilosulous and/or foveolate domatia; stipules deciduous after distalmost several nodes, triangular to ovate, 2-3 mm, densely strigillose to strigose, acute. Inflorescences fasciculate, 0.5-1 cm, few flowered, strigillose to glabrescent; peduncles 1-3 mm, each with a pair of triangular bracteoles ca. 1 mm and fused in pairs. Calyx puberulent to glabrous; ovary portion obconic, ca. 0.8 mm; limb 0.5-0.8 mm, truncate to undulate. Corolla white, funnelform, outside glabrous; tube suburceolate, ca. 2 mm; lobes 5, triangular-oblong, ca. 3 mm, acuminate. Ovary 2-locular; stigma ca. 0.5 mm.

The name Canthium parvifolium Roxburgh has sometimes been applied to the Chinese plants that are here called C. horridum. W. C. Ko (in FRPS 71(2): 10. 1999) considered it a misapplied name, listing it as "Canthium parvifolium auct. non Roxb."
