R. Sundara Raghavan



Herbs, shrubs or trees. Leaves alternate, subopposite or rarely opposite, occasionally crowded on abbreviated shoots, simple or digitately 1-several foliolate, rarely poorly developed and caducous, entire, penninerved; stipules 1 - 2, setaceous or spinescent. Inflorescence axillary or terminal, racemose, corymbose or paniculate, sometimes flowers solitary or in fascicles on short shoots. Flowers bisexual (rarely unisexual and plants dioecious), actinomorphic to slightly zygomorphic, pedicellate, bracteate; receptacle cupular, infundibuliform, campanulate or cylindric with entire, undulate or fimbriate margin; disc various or absent. Sepals 4, sometimes 6 or reduced to 3, biseriate, free or connate below, equal or unequal, valvate or imbricate. Petals 4 (rarely 0, 2 or 8), sessile or clawed. Stamens 4-many, usually borne on a short or elongated androphore; filaments free, sometimes coherent at base or adherent to gynophore; anthers dithecous, basifixed, longitudinally dehiscing. Ovary superior, sessile or supported by a short or long gynophore, unilocular (or by spurious dissipiments divided into 2 or more loculi); ovules few to many, on 2 - 6 parietal placentae, if trilocular then with axile placentation; style short or absent, if present simple or split into 3 arms; stigma simple or capitate. Fruits capsular or baccate and of various shapes, oblong-cylindrical, sometimes torulose or lobed, 1-many-seeded; seeds orbicular to reniform, embedded in pulp or free; endosperm none or scanty; embryo arcuate or incurved; cotyledons folded or convolute.

America, S. Europe, Africa, Asia and Australia, mostly in tropical and subtropical regions; ca 48 genera and 700 species, 7 genera and 55 species in India.
