description

Clarisia racemosa grows as a semi-evergreen tree up to 30–40 meters high. The trunk diameter reaches about 60-90 centimeters.

The simple, alternate, leathery and almost bare leaves have short stalks. The leaves are dimorphic , the leaf blades on young plants are thinner and tailed. The short, runny leaf stalk is up to 1.5 inches long. The ovate to elliptical, elongated or obovate leaves are entire and acuminate, pointed to tail. They are 4-15 inches long and 2-6 inches wide. The leaves are dark green and shiny on the top and light green and slightly hairy on the underside. The veins are finely pinnate with weak, indistinct lateral veins. There are very small, mostly sloping stipules .

Clarisia racemosa is dioecious dioecious . Female specimens are much rarer. The male flowers appear in axillary, multi-flowered and spiked , more or less hairy, up to 10 centimeters long, thin and cylindrical inflorescences. The female flowers appear in (single-flowered), short and thick stalked inflorescences. The inflorescences, which often appear in pairs, are each underlaid by slightly hairy, small bracts . The very small flowers have a simple flower envelope . The sitting, tiny male, up to about 0.8 millimeters in size, whitish flowers have a usually three to six-part, fine-haired perianth , with almost free segments and up to 1–4 small stamens . The seated female, to 2-3 millimeters large green flowers have an up to vierlappiges or nearly verwachsenes, finely hairy at the top, spherical perianth and a top permanent, partly overgrown with the perianth ovary with short style long with two, partly ringed scars branches . They are underlaid by up to 7 small, somewhat hairy bracts.

Orange to red, egg-shaped to ellipsoidal, about 2.5-4.5 centimeters in size, sometimes slightly pointed, single-seeded, smooth, bare fruits, from / in the fleshy perianth ( false fruit ), with persistent bracts are formed. When immature, they still contain a lot of milky juice . The large, ellisoid, greenish, smooth and light brownish veined seed is about 1.5–2 centimeters long.

Taxonomy

The first description was in 1798 by Hipólito Ruiz López and José Antonio Pavón in Syst. Veg. Fl. Peruv. Chil .: 255. Synonyms are Clarisia nitida (Allemão) JFMacbr. and Soaresia nitida Allemão .
