features
Pradosia glaziovii was a tree of unknown height. The young, light gray, curved branches covered with lenticels (cork pores) were covered with dense brown hair fluff. The bundled leaves were arranged opposite, whorled or spirally. They were 10 to 18 inches long and 5 to 8 inches wide. The leaf shape was broadly oblanceolate to obovate. The tip of the leaf was pointed, blunt or rounded. The leaf nerve was eucamptodromic, that is, the secondary leaf veins did not end at the leaf margin, but gradually decreased within the margins. With the leaf veins above, they were connected to a series of cross veins without forming edge loops. The flower clusters consisted of three to five flowers, which were arranged under the leaves. The hairy flower stalks were about 1 mm long. The five sepals were about 3 mm long, egg-shaped, rounded at the tip, covered on the outside with dense hair fluff and smooth on the inside. The corolla was approximately 6.5 mm long and the corolla was approximately 2.5 mm. The stamens were about 3 mm long and smooth. The anthers were approximately 1.5 mm long, lanceolate and smooth. The hairy ovaries were narrowly ovate and had five pollen compartments. The stylus was about 2 mm long and smooth. The stylus head was simple. The egg-shaped, elongated, tubular fruits were solitary.
