Tanaecium jaroba Sw., Prodr. 92: 1788. Fig. 1D, N, R 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, Para , Rondonia , Roraima), Colombia (Amazonas, Antioquia, Atlantico , Bolivar , Caqueta , La Guajira, Magdalena, Sucre), Costa Rica ( Limon ), Ecuador (Napo, Orellana), French Guiana (Cayenne), Guyana, Lesser Antilles (Jamaica, St. Vincent), Panama ( Panama ), Peru (Loreto, Madre de Dios, Ucayali), Trinidad and Tobago, and Venezuela (Amazonas, Apure, Bolivar , Carabobo, Delta Amacuro, Guarico , 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 ).
