Note
|
It is ques- tionable whether the type exists; the species was "described from cultivated plants of Central American origin." The species is probably limited to Panama and Costa Rica. The flowers are described as yellowish-green, red, and yellow; the calyx is described as purplish-red or red-pink. Dressler 4362 notes that the leaves are pink-red beneath. Croat 33632 (MO) has a closeup (photograph) of the leaves and fruits attached to the herbarium sheet.
