    Mexico and tropical America

    Riparian forest at a height from 50 to 200 m
    Characteristics: 

    Perennial shrub 3-5 m tall, although it can reach 10 m, with short trunk and irregularly ramified. The bark is greyish and have lenticels (protuberances acting as pores between tissues) and over the time can become rough.

    The leaves, 7-15 cm long and 0.5-1.2 cm wide, are alternate and entire, with diminished base and short and slightly pointed apex. They are slightly leathery and bright green on the upper side and lighter green on the lower side, with marked central nerve and not very noticeable secondary nervation.

    The fragrant funnel-shaped flowers, 4-6 cm long, appear into cymes (inflorescences that have the main axis finished by a flower). The cyms are usually terminal, although they can also be lateral, and have a peduncle less than 1 cm. The calyx have triangular sepals, 5.5-7 mm long, with elongated tip and the trumpet-shaped or fennel-shaped corolla, 1.2-2.5 cm long, is formed by five yellow or orangish obovate lobes.

    The fruits are fleshy globose drupes, 4-5 cm in diameter, which have slightly compressed sides making four sides. The colour varies according the riping grade: green when young, bright red later and finally black when ripe. In the inside there is a brown triangular or almond-shaped stone containing 2-4 lenticular light grey seeds, about 2-3.5 cm.

    History and curiosities: 

    The scientific name, Thevetia peruviana, consists of the genus name Thevetia, dedicated to the French missionary and botanist André Thévet (1502-1590), and the Latin term peruviana, “Peruvian, from Peru”.
