Cnestis Juss.

Genus

Angiosperms > Oxalidales > Connaraceae

Characteristics

Lianas or ± scandent shrubs, rarely small trees. Leaves exstipulate, petiolate, odd-pinnate; leaflets opposite or subalternate, margin entire. Inflorescences terminal or axillary, solitary or fascicled, terminal one usually paniculate, axillary ones racemose and often borne in axils of fallen leaves on old branches; bracts minute, scalelike or lanceolate. Flowers bisexual. Sepals 5, imbricate or valvate in bud, sometimes petaloid, slightly connate at base. Petals 5, slightly shorter than or equaling sepals, connate at base, emarginate and incurved at apex. Stamens ca. 10, free, all fertile, alternately longer and shorter, those opposite sepals usually longer; filaments free or slightly connate at base. Carpels 5, free; ovary pubescent; ovules 2, erect, collateral. Style longer than ovary; stigma capitate. Follicles 1–5, sessile, pyriform, usually elongated into hornlike processes, dehiscing by a longitudinal, adaxial slit, densely tomentose abaxially, appressed hirsute adaxially; persistent sepals not enlarged. Seed 1, mostly black or dark brown, glossy, flattened; aril basal, oblique; endosperm present.
More
Shrubs, scandent or otherwise, small trees or lianes. Leaves imparipinnate; leaflets opposite or subopposite, entire. Inflorescence terminal or axillary, paniculate or racemose; racemes often clustered in old leaf-bases on older branches. Flowers pentamerous, androecium and gynoecium dimorphic. Sepals free, valvate or slightly imbricate. Petals shorter than, as long as, or longer than sepals. Stamens 10; filaments free or connate at base into short tube. Carpels densely hairy, stigma expanded, rounded or capitate; ovules inserted basally or on ventral suture near base. Fruit a pyriform follicle, the apex usually produced into a curved or twisted rostrum; dehiscence by ventral suture; pericarp densely velutinous and hairy externally, hairy internally, the hairs often urticating. Seed ovoid; testa smooth and shining, aril free, basal, oblique, thin, not conspicuous; cotyledons flattened; endosperm present, fleshy.
Lianas or scandent shrubs, rarely small trees. Leaves imparipinnate. Inflorescences axillary (in Mal. spp.) or terminal, solitary or consisting of fascicled branches inserted on knobs; bracts minute, scale-like to lanceolate. Flowers bisexual (?), 5-merous, heterotri-or-distylous. Sepals (in Mal. spp.) slightly confluent at the base, lanceolate, acute, imbricate in bud. Petals (in Mal. spp.) with indented and incurved tip. Stamens 10, free, all fertile, though the inner ones slightly shorter. Pistils 5, ovary pubescent. Fruits up to 5 per flower, usually some reduced, more or less pear-shaped, slightly beaked, opening by a longitudinal ventral slit, outside densely minutely tomentose, inside appressed-pilose; pericarp thick, probably more or less fleshy when fresh; calyx not enlarged. Seed 1, flattened bean-shaped, partly surrounded by a sarcotesta in the basal part opposite the hilum; endosperm present.
