Features

Pradosia glaziovii was a tree of height not described. The young, light gray, bent, with lenticels ( Korkporen ) covered branches were covered with thick brown hair fluff. The bundled leaves were opposite, whorled or spirally arranged. They were 10 to 18 inches long and 5-8 inches wide. The leaf shape was wide verkehrtlanzettlich to obovate. The blade tip was sharpened short, blunt or rounded. The Blattnervatur was eucamptodrom, that is, the secondary leaf veins did not end on the leaf margin, but decreased gradually within the margins. With the overlying veins they were connected to a series of cross- veins without forming the edge loops. The flower clusters consisted of three to five flowers that were placed among the leaves. The hairy flower stalks were about 1 mm long. The five sepals were about 3 mm long, ovate, rounded at the tip, covered on the outside with thick downy hair present and smooth on the inside. The corolla was about 6.5 mm long and the corolla tube measured about 2.5 mm. The stamens were about 3 mm long and smooth. The anthers were about 1.5 mm long, lanceolate and smooth. The hairy ovary were narrow ovate and had five pollen subjects. The stylus was about 2 mm long and smooth. The stylus head was easy. The ovate - elongate tubular fruits were one seed.

Status

Pradosia glaziovii has been known only from two collections of French botanist Auguste François Marie Glaziou from the 19th century. 1998, the type of the IUCN has been added to the list of extinct species.
