Tambourissa peltata (Bois Tambour).


They are trees or bushes, being dioecious, heterophyllous and reaching 12-15 m in height. The trunk can reach 30-40 cm in diameter, having a smooth, brown bark, which is fissured longitudinally. Plantlets are smooth. Adult leafy branches are smooth, 3-7 mm in diameter, rough to sub-rounded. The adult leaves are ternate to sub-alternate and smooth. The petiole is 12-25 1-2 mm.

 The lamina can be largely to narrowly oboval, elliptical or rarely oval, 6-15 (-18) 3-7 (-8.5) cm. The tip can be acuminate to pointed, frequently obtuse, with the base being cuneiform. There are 6-9 (-12) pairs of secondary veins, which make an angle of 5-650 with the midrib. Venules are prominent, reticulate and visible on both surfaces of the leaf while the margin is highly revolute.

 The leaves of plantlets and shoots are opposite, having a red petiole. The lamina is narrowly oboval and the margin bears 1-3 pairs of short teeth at the top.

 They are ramiflorous plants bearing inflorescences on the defoliate part of branches or are cauliflore plants with inflorescences on the superior part of trunks.

 Flowers are solitary or in fascicules of 2-3. They are rarely axillary and are borne on young leafy shoots. Male flower buds are smooth, globular to ellipsoidal, 1.2-1.8 cm long and 1-1.4 cm in diameter. They are apicualte and are provided with 5-6 small smooth, pointed tepals. Pedicels (together with peduncle) measure 0.6-2 cm 1.5-3 mm, bearing triangular, ciliated bracteoles that reach 1.5 mm in length. They can be few to numerous. At anthesis, the receptacle has a diameter of 3-5 cm and is deeply split in 4-6 (-7) thick, reflexed lobes. Stamens (200-400) vary from ovoid-deltoid to linear or narrowly oval. They measure 4-7 1.5-3 mm, are sessile or have a short filament.  The locules are separated or confluent at the top, occupying almost the whole length. The connective is large. The internal surface of the receptacle is smooth, rarely bearing hairs.

 Female flower buds are smooth, largely napiform-depressed; 7-9 mm long and have a diameter of 1.4-1.7 cm. They are apiculate and bear 4 small tepals. Pedicels (together with peduncle) measure 6-12 2 mm and are smooth. They bear the same bracteoles as the male flower. The receptacle is flat, concave, and more or less discoid where the central part has a diameter of 2.3-3 cm, being deeply split into 4-7 triangular lobes, finally reflexed and wrinkled on the internal surface. There are 400-500 styles, which are difficult to be distinguished, each in the form of a column with 6 faces, 0.3-0.5 mm long and 0.3-0.4 mm in diameter. The tip varies from flat to depressed.

 Fruits are found solitary in the old branches, more rarely on the superior parts of the trunk. Sometimes, they are produced in large quantities. They measure 4-13 cm in diameter and 1.5-6 cm in height. The external surface is corky, brown and spotted. The wall is 0.8-2 cm thick.  The orifice is large, sub-entire, reaching 3/4 or more of the total diameter. The internal surface is corky, brown and bears numerous styles.

 Ripe carpels are ovoid-compressed, 0.9-1.3 cm long with a dark brown endocarp.
