BUNCHOSIA Rich. ex Juss.

Arbustos o árboles. Hojas generalmente con glándulas impresas en el envés de la lámina; estípulas libres, dispuestas sobre el pecíolo en la base o ligeramente más arriba. Inflorescencia un pseudoracimo, simple o menos comúnmente ternado, axilar sin hojas vegetativas o terminando una rama lateral con 1 par de hojas vegetativas, 1 o ambas bractéolas a menudo con 1 (2) glándulas abaxiales excéntricas; cáliz generalmente con 8–10 glándulas decurrentes; pétalos amarillos o blanquecinos, glabros; estambres 10, generalmente glabros, las anteras más o menos semejantes; gineceo 2- ó 3-carpelar, ovario con carpelos connados y lóculos tantos como carpelos, cada lóculo fértil, estilos tantos como carpelos, libres o parcial a completamente connados y luego aparentemente sólo 1 y robusto, los estigmas terminales, grandes, subpeltados o aparentemente capitados. Fruto una drupa indehiscente (en realidad una baya), amarillo, anaranjado o rojo en la madurez, con 2 ó 3 pirenos libres con 1 semilla en un exocarpo carnoso común, cada pireno con una pared cartilaginosa, frágil y lisa.

Género con ca 65 especies distribuidas desde México hasta el sur de Brasil y Argentina, también en las Antillas; 8 especies native and 1 cultivated se conocen en Nicaragua. La mayoría de las especies de Bunchosia son consistentemente 2- ó 3-carpeladas, y las especies que son de alguna manera similares pueden a menudo distinguirse una vez que se conoce la naturaleza del gineceo. Ese carácter se puede interpretar durante todos los estados desde el botón floral hasta el fruto, pero para una buena interpretación se necesita a menudo de un corte transversal, el cual requiere que el material seco sea ablandado en agua caliente.

1. Abaxial leaf surface initially sericeous, the trichomes straight and appressed with stalks 0—0.05 mm, sometimes rapidly glabrescent.

 2. Leaves irregular in shape, repand and undulate; bracts frequently subtending the peduncles of two flowers; plants cultivated in Nicaragua … B. glandulifera

 2. Leaves regular in shape, not repand or undulate; each bract subtending the peduncle of only one flower; plants native to Nicaragua.

  3. Larger leaves (14.5--) 18.5--38 cm de largo y (6.6) 8—16.5 cm de ancho, longest trabeculae on abaxial surface (0.8) 1—1.5 (1.75) mm; stipules (1.5--) 2.5—6.6 (--11) mm; stigma lobes 3, ovary and fruit with 3 locules … B. dwyeri

   4. Petioles 5--12 mm; leaf abaxial glands per side of midrib 1 or 2 proximal and adjacent or close to midrib with an additional 0 or 1 more distal halfway between margin and midrib and/or 0—10 more or less in a row closer to margin than midrib (rarely on margin) or occasionally random; ovary densely sericeous (rarely with few trichomes), styles connate; fruit 20—30 mm de largo y 14--20 mm de ancho, ellipsoid (sometimes nearly globose)… B. nitida

   4. Petioles (1.5) 2—4 (6) mm; leaf abaxial glands per side of midrib (0) 1 (2) proximal and between midrib and margin (sometimes with an additional at leaf apex); ovary glabrous, styles free or connivent or connate but usually free apically or separating easily; fruit (10) 12--17 mm de largo y 10--14 mm de ancho, ovoid or globose … B. ocellata

1. Abaxial leaf surface tomentose or velutinous, the trichomes various but including either trabeculae sinuous and/or tortuous or long stalked (0.1—1.2 mm), pubescence persistent or patchily lost.

 5. Young branchlets usually developing lenticels on flower-bearing portions, not obscured by pubescence; abaxial leaf surface frequently patchily glabrescent; abaxial surface of sepals glabrous or nearly so, sometimes eglandular or often glands poorly developed … B. mesoamericana

 5. Young branchlets not developing lenticels on flower-bearing portions (or lenticels obscured by pubescence); abaxial leaf surface pubescence usually more or less persistent; abaxial surface of sepals usually densely pubescent at least medially, always glandular, glands normally developed.

  6. At least some of the trichomes of the abaxial leaf surface with the trabeculae tortuous or sinuous and longest stalks 0.05—0.25 (0.3) mm; stigma lobes 2 or 3, ovary and fruit with 2 or 3 locules.

   7. Stigma lobes 3, ovary and fruit with 3 locules; peduncle in flower absent to 0.5 mm (in fruit to 1 mm); inflorescences frequently bifurcate; mature fruit 8—12 mm de largo y 10—15 mm de ancho ….B. bifurcata

   7. Stigma lobes 2, ovary and fruit with 2 locules; peduncle in flower 0.75—3.5 mm (in fruit to 5 mm); inflorescences simple pseudoracemes; mature fruit 15—25 de largo y 10—25 mm de ancho… B. heterotricha

  6. Trichomes of the abaxial surface with the trabeculae straight to only slightly sinuous and longest stalks 0.25—1.5 mm; stigma lobes 3, ovary and fruit with 3 locules.

   8. Trichomes of the abaxial surface with the longest stalks 0.25—0.4 (--0.6) mm; stipules (0.75) 1--2 (2.5) mm; distal abaxial glands per side of midrib (0) 1--8 (10) more or less in a row closer to margin than midrib (rarely halfway between midrib and margin), occasionally one gland out of alignment; sepals loosely cupping to spreading away from flower bud prior to anthesis …B. costaricensis

   8. Trichomes of the abaxial surface with the longest stalks (0.2) 0.5—1.2 mm; stipules (2.5--) 3.5—9 mm; distal abaxial glands per side of midrib (6) 9—44 (--56) randomly arranged; sepals tightly appressed to flower bud prior to anthesis … B. macrophylla
