Bunchosia heterotricha A. Pool, Novon 31: 222. 2023.
Small to large trees or shrubs, 2--17 (25) m, young branchlets without lenticels (lenticels sometimes developing in second year but not on flower-bearing portions), densely to sparsely appressed-sericeous, spreading-sericeous to appressed-tomentose, glabrescent. Larger leaves (7.5) 8—20.5 cm de largo y (4.2) 5—12.5 cm de ancho, obovate to wide-elliptic or wide-lanceolate, (rarely elliptic), abaxial surface persistently tomentose, trichomes T (also rarely Y and V) -shaped, sessile to longest stalks (0.05) 0.1—0.25 (0.3) mm, longest trabeculae 0.75—2 mm, sinuous, tortuous, and straight, the sinuous sometimes obscured by the longer stalked trichomes with straight trabeculae and the tortuous sometimes subtle (i.e. appearing straight but with a very tight spiraled twisting) and few in number, rarely straight missing, abaxial glands per side of midrib 1--3 proximal and adjacent to midrib, (sometimes difficult to see due to position and pubescence) with an additional (0) 1—7 more distal more or less in a row closer to margin than midrib, most proximal (0.3--) 0.75—1.5 mm; stipules 1—2.1 (--2.5) mm; petioles 2.5—12 mm. Inflorescences from axils with mature or developing leaves or leaves lost but from, or immediately below, current leaf-bearing portion of branchlet, or from axils of prophylls of lateral branchlets, single, simple pseudoraceme, pseudoracemes 5—12 (16) cm with 8—30 flowers, bracts (excluding the most proximal) 1.5—2 (2.5) mm, peduncles 0.75—3.5 mm (to 5 mm in fruit), bracteoles 0.75—1.5 (2) mm, one or both bracteoles per pair subtending each flower with one gland or an enlarged keel, bracteole gland 0.4—1.25 mm, decurrent or completely positioned on bracteole, pedicel (2) 2.5—6 (--9) mm (to 10 mm in fruit). Flowers with sepal glands (1.5--) 2—3 mm, sepals extending 0.5--1.5 mm beyond glands, loosely cupping to apically spreading away from flower bud prior to anthesis, abaxial surface densely sericeous or tomentose with narrow glabrous rim, marginally ciliate; ovary 2-locular, with few trichomes to densely tomentose, styles connate, with few trichomes to densely tomentose, stigma lobes 2, equal, connate or free. Mature fruit 15—25 mm de largo y 10--25 mm de ancho, 2-locular, more or less globose, not or only slightly 2-lobed, nearly glabrous with few scattered trichomes, smooth, shiny, red, apex slightly apiculate.
Common, moist or deciduous forest, pacific and north central Nicaragua; 200—1600 m; fl may-jul, fr jul-oct; Stevens 10231, 30112; Guatemala, Honduras, El Salvador, and Nicaragua.
This species was treated in the printed Flora as Bunchosia sp. B. Specimens of Bunchosia heterotricha vary greatly in the proportions of the different types of trichomes found on the abaxial leaf surface and it can be confused with a number of other species when in fruit.
