Type.

Jamaica, s. loc., s.d., O. Swartz s.n. (holotype, S not seen).

Habitat and distribution.

Tanaecium jaroba grows in flooded and swampy forests ( Gentry 1997) in Bolivia (Beni, La Paz), Brazil (Acre, Amazonas, Mato Grosso, Mato Grosso do Sul, Pará, Rondônia, Roraima), Colombia (Amazonas, Antioquia, Atlántico, Bolívar, Caquetá, La Guajira, Magdalena, Sucre), Costa Rica ( Limón), Ecuador (Napo, Orellana), French Guiana (Cayenne), Guyana, Lesser Antilles (Jamaica, St. Vincent), Panamá ( Panamá), Peru (Loreto, Madre de Dios, Ucayali), Trinidad and Tobago, and Venezuela (Amazonas, Apure, Bolívar, Carabobo, Delta Amacuro, Guárico, Zulia).

Phenology.

Flowering: April to August and November to December; fruiting: March to August and December.

Notes.

This species has the longest wide infundibular white flowers in the whole tribe Bignonieae , with corollas up to 35 cm long ( Gentry 1997, Howard 1989). It is most morphologically similar to T. crucigerum , with which it shares ellipsoid fruits that bear wingless woody seeds (Tab. 1 ). Tanaecium jaroba differs from T. crucigerum by the glabrous or pubescent leaflets abaxially (vs. whitish-tomentose leaflets abaxially in T. crucigerum ).
