Small tree, to 17 m tall and 27 cm dbh, glabrousexcept young parts with short appressed trichomes. Petioles 1-1.5cm long, slightly canaliculate; blades ovate to ellip­tic orlanceolate-elliptic, long-acuminate and sometimes falcate at apex,acute to rounded at base, 6-20 cm long, 3-6 cm wide, usuallybearing weak tufts of trichomes (domatia) in lower vein axils onunderside of leaves; midrib arched, the reticulate venationconspicuous on both surfaces. Panicles 6-12 cm long, terminal or inupper axils; flowers bisexual, white, ca 5 mm wide, with sweetaroma, in usually subcorymbiform panicles; peri­anth lobes 6,fleshy, spreading, densely short-pubescent, the inner 3 usuallynarrower; stamens exserted, the outer 6 with short filaments andthe anthers ± reniform, the glands white or orange, subtendingand alternating with outer stamens (often larger than anthers), the3 inner stamens closely surrounding and ± equaling the lengthof the style, alternating with 3 shorter staminodia; ovaryglabrous. Fruits fleshy, 1-seeded, ± rounded, green andspeckled, becoming black at maturity, to 1.5 cm diam, the pediceland cupule conical, bright red, together ca 1 cm long. Croat9556.

Frequent along the shore, especially on the northside of the island; occasional in the younger forest. Some flowersmay be seen in all months of the year, but flower­ing occursprincipally in two waves, one at the beginning of the dry season(December to March) and one at the beginning of the rainy season(May to July). The fruits usually develop within a few months, butsome have been seen as late as October. Individual plants floweringin March were seen again with both flowers and fruits in the rainyseason.

Standley mistakenly reported this species asN. glabres­cens Benth., which has affinities withN. globosa and occurs in Panama only along theAtlantic slope.

Nicaragua to Panama, south to Ecuador, Peru, and Brazil; at lowelevations. In Panama, known principally from tropical moist forestin the Canal Zone, but also from tropical wet forest inColón.
