Inflorescences cymose, few-flowered, sometimes reduced to a single flower, axillary. Flowers medium-sized; calyx 5-lobed, or sometimes connate basally, the lobes somewhat unequal, bearing squamellae within; corolla salverform to subsalverform, without appendages, the limb 5-lobed, sinistrorsely convolute; stamens 5, included, the anthers free and not agglutinated to the stig- ma, without an enlarged connective; gynoecuim 2-carpellate, apocarpous, the ovary superior, the ovules numerous, the nectary adherent to the ovary, the style 1, the stigma pentagonal-umbraculiform. Fruit apocarpous, follicular, spherical to sub- spherical; seeds many, naked, embedded in a fleshy aril.
Habit Shrubs or trees
Distribution A genus of about nine species, mostly in northeastern South America; two species extend north into Panama.
Note Markgraf (Notizbl. Bot. Gart. Berlin-Dahlem 14: 151-184. 1938) resur- rected several genera which had been reduced to Tabernaemontana L. The validity of all the genera which Markgraf recognized and separated from Tabernaemon- tana is questionable, but judging from the Panamanian material, Bonafousia de- serves generic status.
