Stixis Lour.


Shrubs, unarmed, scandent; branches lenticellate, verticillate. Leaves exstipuiate, simple, rarely 3-foliolate, pellucid-dotted. Inflorescence axillary, many-fowered, racemose or paniculate. Flowers yellow, short-pedicelled; bracts caducous. Torus short, disc-shaped, persistent with sepals inserted along margins. Sepals 6, in two whorls of 3 each, valvate or imbricate; petaloid, outer sepals covering margins of inner ones. Petals absent (rarely petaloid appendages seen). Alidrophore short, subconical. Stamens many, nearly equalling sepals. Ovary shortly stipitate, 3-loculed with axile placentation, each placenta 5 - 10-ovuled; style simple or 3-armed; stigma 1 - 3, subulate. Fruit drupaceous, fleshy on a woody stalk, 3-valved; stone 1 (-2)-seeded, ovoid; cotyledons thick, fleshy, unequal, the larger embracing the other.

Literature. DUTTA, R. M. & D.P. DAM (1989). The genus Stixis Lour. (Capparaceae) in Inida. J. Econ. Tax. Bot. 13: 17 - 21 . JACOBS, M. (1963). The genua Stixis (Capparaceae)- a census. Blumea 12: 5 - 12, f. 1a - g. SUNDARA RAGHAVAN, R. 1986 (1988) New taxa in Capparaccae. Bun. Bot. Surv. India 28: 185 - 192, tt. 1 - 4.

Notes. The division of Stixis Lour. into Roydsia Roxb. (style short or 0) and Alytostylis Hook. f. (style long with 3 stigmas) is artificial and not convincing.
