Uncarina platycarpa is a species of the genus Uncarina in the sesame family (Pedaliaceae).
description
Uncarina platycarpa grows as a small tree with a short, thickened trunk and a few long, unbranched, upward branches. It grows up to 3 meters high. The deeply lobed leaves have a large terminal lobes and four smaller lateral lobes that are only slightly three-lobed. The leaf blade becomes 20 centimeters long and wide. The green upper side of the leaf is covered with only a few, simple hairs with a reduced head and individual mucous glands with a square head. The underside of the leaf appears greyish green through a loose covering with short-stalked mucous glands with a square head and long, simple hair, which occasionally have a reduced head.
The inflorescence consists of cymes with 3 to 7 individual flowers that form dense clusters. The golden yellow flowers have a dark red throat. The flower tube is about 4.5 to 7 inches long.
The side of the heavily compressed fruit is almost square in the side view and has a short, triangular beak . Furthermore, two 12 to 15 millimeter wide wings are arranged on the sides of the approximately 6 by 6 centimeter large fruit, at the ends of which there are spike-like extensions. Only hook spikes are formed. They are five or six in a row, are up to 12 millimeters long and do not extend beyond the beak. The widened bases of the spines form a crest up to 3 millimeters high. No false partitions are formed. The obovate seeds are 10 millimeters long and 9 millimeters wide and have 1.5 millimeter wings.
