Part of the The Families and Genera of Vascular Plants book series (FAMILIES GENERA, volume 3)


Trees, shrubs, sometimes scandent, unbranched suffrutices or rhizomatous geophytes, sometimes succulent, glabrous, from less than 10 cm to over 40 m tall. Aerial stems often showing characteristic persistent leaf scars. Leaves alternate, distichously or spirally arranged, entire, ovate, strap-shaped or ensiform, usually amplexicaul with a sheathing base, occasionally exceeding 2 m in length, usually much shorter, sometimes variegated, the upper ones gradually to rather abruptly transformed into the inflorescence bracts. Inflorescence terminal, sometimes apparently axillary on leafless dwarf shoots, racemose, capitulate to paniculate; floral bracts and bracteoles often obsolescent. Flowers often grouped together on articulated pedicels with a longer or shorter pericladium, usually white, sometimes flushed with green or purple, fragrant, nocturnal. Perianth with a shorter or longer tube and 6 equal segments. Stamens 6, as long as the free perianth lobes and inserted at their base in the throat; filaments often inflated and spindle-shaped; anthers versatile, opening latrorsely. Ovary superior, cylindrical to bottle-shaped, with 3 locules, each containing a single ovule; septal nectaries present; the style equaling the stamens; stigma capitate to shallowly 3-lobed. Fruit a thin-walled berry, (depressed-) globose or ellipsoid, sometimes 2- or 3-lobed, usually bright orange when ripe, containing up to 3 large seeds lacking a testa but enclosed in an obsolescent layer of sclerotic endocarp cells.
