Description
|
Lianas or sprawling shrubs, sometimes epiphytic. Leaves petiolate, chartace- ous or coriaceous. Inflorescences racemes; nectaries hollow, tubular, horn-shaped, or clavate, often auriculate, inserted at the bases of the flowers. Flowers often fra- grant, pedicellate; bracteoles appressed to the calyx, persistent; sepals 5, slightly unequal, persistent; petals 5, rarely 3, free, from shortly connate basally to con- nate throughout nearly their whole length, reflexed at anthesis; stamens 5 or 3, the filaments flattened, wide, often connate basally and often abruptly narrowed apically, often adnate to the bases of the petals, the anthers ovate to subglobose; ovary incompletely (3-)5-loculed, often pentagonal, the stigma sessile, mostly large and radially 5-lobed. Fruit subglobose, the pericarp often very thick, woody, apiculate through the persistent stigma, the mode of dehiscence unknown; seeds rather few, shining, reticulate.
