Flora of Barro Colorado Island

Neea amplifolia

Donn. Sm., Bot. Gaz. (Crawfordsville) 61:386.1916

N. pittieri Standl.

Dioecious shrub, usually less than 2 m tall (to 7 m); younger branches densely ferruginous-pubescent, be­coming glabrate in age. Leaves opposite or nearly so; petioles 0.5-5 cm long, canaliculate, often somewhat reddish; blades ± elliptic, ovate to obovate-elliptic, abruptly to gradually long-acuminate, obtuse to attenuate at base, 7-36 cm long, 3-15 cm wide, entire, glabrous above, glabrate to puberulent below. Inflorescences terminal, obscurely dichasial thyrses, essentially glabrous to densely        ferruginous-pubescent, 4-15 cm long, bearing few to many flowers; staminate flowers narrowly      tubular-­urceolate, 5-10 mm long, about 2.5 mm wide, the peri­anth with 5 short lobes, the limb weakly spreading; sta­mens 8, to 5.5 mm long, included, attached near base of tube; filaments of different lengths, united into a short tube around the sessile pistillode. Pistillate flowers similar to staminate flowers but with a prominent constriction about one-third of the way down the perianth tube, thickened within at point of constriction; style and stam­inodia (usually 9) fitting tightly through the constriction, included, later exposed when the upper third of perianth above the constriction withers and falls; staminodia held just above constriction; ovary narrowly elliptic, sessile, at first loosely enveloped by perianth, by maturity com­pletely filling it; style slender; stigma with few divisions. Anthocarp      elliptic-oblong, ca 1 cm long, at first reddish, becoming violet-purple at maturity, the persistent peri­anth fleshy and sweet; seed solitary, somewhat shorter than fruit. Croat 4213, 5626.

Frequent in the forest. Flowers throughout the year, most commonly from March to September. The fruits are most common from June to December.

Standley (1933) also reported N. psychotrioides Donn. Sm., which is a Costa Rican species earlier confused with N. laetevirens Standl. of the Atlantic slope of Panama. N. laetevirens probably does not occur on BCI. Most of the material from BCI assigned the name N. psychotrio­ides isN. amplifolia. A single sterile collection, Shattuck 121, is in doubt; it does not appear to be typical of N. amplifolia. However, it can be stated with confidence that a second species of Neea does not now occur on the island. Leaves of the species are consistently host to var­ious cryptogamic epiphytes, including mosses and lichens.

Costa Rica and Panama. In Panama, known principally from tropical moist forest in the Canal Zone, all along the Atlantic slope, and in Darien; known also from pre­montane wet forest in Colón Chiriqui, and Coclé and from tropical wet forest in Colón.
