    Tree to 50 m, the bark with vertical ridges, wood extremely hard.
    Leaves palmately 5–7-foliolate leaflets lanceolate to ovate, 9–30 × 3.7–13.5 cm, acuminate at apex, rounded to cuneate at the base, stellate-pubescent in axils of lateral nerves beneath petiole 7–23 cm long, glabrous.
    Flowers in terminal panicles calyx 7–15 mm long, stellate-pubescent corolla yellow with reddish lines in the throat, tubular to funnelshaped tube 3.5–5.7 cm long, 1.2–2.2 cm wide at throat, lobes 2.2–3.8 cm long.
    Fruit linear-cylindrical, 29–61 × 1–2.9 cm, glabrous or stellate–pubescent seeds 3.5–4 × 0.9–1.1 cm.
    Native of Mexico to Venezuela and Peru. Has been reported from Uganda, Entebbe Botanic Gardens and also from Kenya, Nairobi Arboretum but all this material has proved to be T. impetiginosa; since it may occur (see note) a description is given. A sterile specimen from Kenya (Kwale District: Mazeras–Gandini, 22 April 1992, Luke 3095) might be T. guayacan as it was originally named. The thin young leaves have dried black and are pubescent above, more densely so beneath, the leaflets are long-acuminate. More adequate flowering material is needed.



    Native to:

    Belize, Colombia, Costa Rica, Guatemala, Honduras, Mexico Gulf, Mexico Southeast, Mexico Southwest, Nicaragua, Panamá, Peru, Venezuela
