Distribution
At present, Basella comprises five species native to southeastern Africa, Madagascar, and possibly Asia. One African species, B. paniculata, is deviating, and it is possibly better placed in a genus of its own.
Morphology General Habit
Scandent vines or sometimes procumbent to erect plants
Morphology Leaves
Leaves petiolate, not decurrent; leaf blade lanceolate to broadly elliptic or cordate, entire, obtuse to acuminate at apex
Morphology Reproductive morphology Flowers
Flowers sessile, partly sunken into rachis or not, bisexual, chasmogamous or cleistogamous, scentless
Morphology Reproductive morphology Flowers Androecium Stamens Filaments
Filaments straight or obscurely reflexed in bud, connate and fuLsed at base or up to c. 3/4 of their length with petals into a tube; anthers dorsifixed, slightly to distinctly deltoid, with thecae free at apex, dehiscent by longitudinal slits
Morphology Reproductive morphology Flowers Calyx
Sepals shorter than petals to equalling them in length, ovate to elliptic, free from each other or partly connate, without dorsal structures, ± obtuse at apex, at anthesis greenish, whitish, or reddish, in fruit pale and ± dry, thin, or purple to black, thick and juicy
Morphology Reproductive morphology Flowers Corolla
Petals uniform, ovate to elliptic, connate only at base or up to c. 2/3 of their length, ± obtuse at apex, at anthesis greenish, whitish, or reddish, in fruit pale and ± dry, thin, or purple to black, thick and juicy
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary globose to pyriform, sometimes lobed or ridged; style 1, 3-parted almost to the base, or styles 3, usually not persistent, rarely with persistent base in fruit; stigmas linear to clavate, or undifferentiated
Morphology Reproductive morphology Fruits
Fruit globose to pyriform, in cross section rounded to somewhat hexagonal, tightly enclosed, partly or completely, by persistent, sometimes eventually disappearing perianth.
Morphology Reproductive morphology Inflorescences
Inflorescences unbranched or branched spikes, usually with stout and fleshy axis sometimes thickened in fruit, pedunculate or not
Morphology Reproductive morphology Inflorescences Bracts
Bracts ± triangular
Morphology Reproductive morphology Inflorescences Bracteoles
Bracteoles subtending flower, minute to distinctly developed, ovate to triangular, free
Morphology Stem
Stem glabrous, rarely puberulent when young, not producing tubers
