Androglossum Champion ex Bentham; Changiodendron R. H. Miao.
Woody climbers or scandent shrubs, sometimes suberect, rarely erect, deciduous or evergreen. Branches terete or flexuose, striate, pubescent or glabrous, unarmed (except S. japonica); branchlets with bud scales persistent at bases, pubescent or glabrous. Leaves simple, glabrous or slightly pubescent, margins mostly entire or sometimes minutely erose, but never toothed, mostly narrowly cartilaginous and revolute. Flowers bisexual, rarely polygamous, axillary, solitary, or few and arranged in cymes or subumbellate panicles, actinomorphic. Sepals (4 or)5[-7], persistent, imbricate, green, white, yellow, or purple. Petals usually (4 or)5(or 6)[or 7], persistent or not, longer than sepals. Stamens (4 or)5(or 6), all fertile; filaments ± flattened, adherent to bases of petals; anthers introrse or extrorse, upright or inflexed. Carpels 2; styles 2, persistent, connate; ovules 2 per carpel, ± superimposed, half-anatropous. Fruit a schizocarp, with 2 drupelets, usually 1 developed, drupelet laterally compressed; mesocarp white, reddish, or blue, rather thin, fleshy; endocarp crustaceous, with prominent veins forming a reticulate pattern (foveolate). Seed 1[or 2], subreniform; testa leathery, dotted; embryo with 2 undulate, or strongly folded cotyledons, radicle curved.
About 30 species: S and SE Asia; 17 species (seven endemic) in China.
See Water, A taxonomic revision of the genus Sabia (Sabiaceae) (Blumea 26: 1-64. 1980). Sabia cavaleriei H. Léveillé and Sabia feddei H. Léveillé (Repert. Spec. Nov. Regni Veg. 9: 456. 1911) are both synonyms of Orixa japonica Thunberg in the Rutaceae (see Fl. China 11). Sabia edulis H. Léveillé (Fl. Kouy-Tchéou, 379. 1914-1915) is a species of Iodes Blume in the Icacinaceae (see Fl. China 11). Sabia esquirolii H. Léveillé (Repert. Spec. Nov. Regni Veg. 9: 457. 1911) is a synonym of Gardneria multiflora Makino in the Loganiaceae (see Fl. China 15: 328. 1996).
