Petals valvate, connate at the base, the outer produced on their outside into a wing or spur. Stamens numerous, their anther cells not locellate; connective expanded above the anther into a truncate disk. Carpels several to numerous, united into a fleshy syncarpium; ovule solitary, basal, erect.

Note
|
Rollinia chocofnsis R. E. Fr., which, according to E. P. Killip, occurs "along the Pacific coast of Colombia from the Darien region of Panama into northern Ecuador" (cf. R. E. Fries in Sv. Vet.-Akad. Handl., ser. 3, 2410: 18. 1948), might possibly be added to the above. As, however, no specimen from Panama has been available and as it is hard to distinguish it from closely related species, it is perhaps better for the time being not to include it in the flora of that country.
