Description
|
Dioecious shrubs and small trees to about 7 m. tall. Branches moderately stout, densely ferruginous-pubescent to glabrate. Leaves petiolate, the blade ovate- to obovate-elliptic, usually more or less caudate-acuminate, obtuse to cuneate at the base, 7-36 cm. long, 3-15 cm. broad, firmly membranaceous, glabrous above but frequently more or less puberulent beneath, the petiole 0.5-5.0 cm. long. Inflorescences 4-1-5 cm. long, essentially glabrous to densely ferruginous-pubescent, rather few-flowered to many-flowered and occasionally greatly proliferous and the flowers and bracts becoming phylloid; cymules obscurely dichasial, both terminal and lateral flowers subsessile or with essentially similar short stout pedicels. Stami- nate perianths tubular-urceolate, 5- 10 mm. long, 2-3 mm. broad, essentially glabrous to minutely puberulent to essentially glabrous. Anthocarps ellipsoid to ovoid, 7-12 mm. long, glabrous to minutely puberulent, red.

Note
|
Neea amplifolia usually can be keyed without difficulty from the two preceding species, particularly by means of the inflorescence characters, the predominantly larger leaves and staminate perianths, and the more frequent and abundant indu.- ment. In all respects intermediates occur, nevertheless, and the relative abundance of disparate specimens, particularly from Bocas del Toro, where N. laetevirens also is abundant and variable, provides grounds for strongly suspected hybridization. The proliferation and phyllody of the inflorescence is a frequent and puzzling propensity of this species, the agent of which is obscure. In addition, both in N. amplifolia and in N. laetevirens, the terminal staminate flowers occasionally develop at the expense of the lateral.
