Genus

Angiosperms > Santalales > Santalaceae

Characteristics

Aerial stem-parasitic shrubs, densely velvety tomentose on young parts. Stems much-branched; branches with a pair of prophylls at the base of the first internode and a decussate pair of rudimentary leaves (cataphylls) just above the base. Leaves opposite, petiolate, entire, bifacial, curvinerved, usually with 3 or 5 veins visible on the upper surface. Inflorescences terminal, of 1 or more fan-shaped cymules, these solitary or in a racemose or spicate arrangement; cymules with 3-13 flowers developing successively from the centre outwards, with the central flowers male and the lateral flowers female; bracts small, triangular, in pairs subtending each cymule. Male flowers globose, c. 1 mm in diam., shortly stipitate, usually 4-merous; tepals triangular, valvate; anthers depressed-ovoid or reniform, many-loculate, opening by pores, on a short filament. Female flowers cylindric or barrel-shaped, usually less than 2 mm long, 4-merous; tepals triangular; stigma small, nipple-shaped. Fruit narrowly ellipsoid to almost globose, crowned by the persistent tepals. Fig. 5. Fig. 6. Fig. 7. Fig. 8.
More
Erect or pendulous shrubs, the whole plant or at least young parts with a dense indumentum of dendritic or stellate hairs and/or peltate scales. Stems much-branched, often dichotomous below inflorescences; branches with 1 pair of acute prophylls and 1 pair of acute cataphylls at right angles to them near base. Leaves petiolate, curvinerved. Inflorescence terminal, of 1 or more small fan-like cymes (cymules) each subtended by a pair of narrow acute bracts; cymules solitary or in determinate or indeterminate conflorescences; flowers in each cymule 3-13, developing centrifugally, the central flower(s) male, lateral flowers female. Male flower 4-merous, with an ovoid to reniform anther opposite each tepal on a short filament; anthers many-locular. Female flower 4-merous; ovary cylindrical to barrel-shaped. Fruit mostly ellipsoidal, crowned by the persistent tepals.
