description

Bagassa guianensis grows as a deciduous to semi- evergreen tree about 30–40 meters high. The trunk diameter reaches 50–90 centimeters or a little more. The bark is brownish and relatively smooth to slightly cracked, furrowed or somewhat scaly and there are smaller roots . The tree carries a sweet, sticky, and drinkable milky sap .

The simple, stalked and slightly leathery leaves are cross opposite. The somewhat hairy petiole is about 5–12 inches long. The leaves are egg-shaped to triangular or rounded and partly more or less three-lobed to three-toothed (especially the young leaves), the edge is whole to notched, serrate. The leaves are 12-27 centimeters in size and pointed to pointed, as well as slightly heart-shaped to rounded at the base, they are almost glabrous on the top and dense and short, finely hairy on the underside. The veins are threefold and raised on the underside. There are sloping and finely hairy stipules . The young leaves are scaly.

Bagassa guianensis is dioecious, dioecious, with axillary and very many-flowered inflorescences that appear individually or in pairs. The very small, densely arranged flowers with simple perianth have a four-piece, more or less finely hairy, 1-2 millimeters long perianth . There are several hairy bracts . The male, green to reddish-brownish, roughly cylindrical inflorescences are stalked, about 5–12 centimeters long, narrow spikes with a finely hairy stalk and a diameter of about 4–8 millimeters. The female, greenish inflorescences are small, stalked, about 1–2 centimeters large heads with a finely haired, thick stalk. The male flowers have 2 (4) stamens and an awl pistillode. The ovary of the female flower is upper constant, lateral something with two almost seated and pfriemlichen scars branches .

The rounded, orange-yellow and knobbed fruit associations are about 2.5–4 centimeters in size. The many small, 5-8 millimeter large, partly stalked single fruits, drupes with a membranous exocarp are enclosed by the fleshy, tubular, about 1.2-1.4 centimeter long perianth (false fruit ). The orange-brownish, ellipsoidal and smooth, bony seeds (stone core) are about 3–3.5 millimeters in size.

Taxonomy

The first description of the genus Bagassa and the species Bagassa guianensis was in 1775 by Jean Baptiste Christophe Fusée Aublet in Hist. Pl. Guiane T. 2, Suppl. 15 and T. 4, t. 376. Synonyms are Bagassa sagotiana Burch. ex Benth. & Hook.f. , Bagassa tiliifolia (Desf.) Benoist , Laurea tiliifolia Gaudich. , Piper tiliifolium Desv. Laurea Gaudich is a synonym for the Bagassa genus .

use

The sweet and sour fruits or the fruit dressings are edible.

The rather heavy, hard and durable wood is known as bagasse (a) or tatajuba as well as cow-wood , it is used for some applications.
