Uncarina perrieri is a species of the genus Uncarina in the sesame family (Pedaliaceae).
description
Uncarina perrieri grows as a small tree with a strongly branched crown and overhanging branches. It reaches 3 meters in height. The approximately pentagonal and entire leaf blade is up to 14 centimeters long and up to 14 centimeters wide. However, three to five, sometimes up to seven, indistinct lobes can be formed, the edge of which is only slightly curved. Short-stalked mucous glands with a square head are present in small numbers on both sides of the leaf. On the underside, there are isolated long hairs that rarely form a reduced head.
The inflorescence consists of cymes with 1 to 3 single flowers that do not form clusters. The golden yellow flowers have a dark red throat. The flower tube is about 4.5 inches long.
The side of the fruit, which is slightly compressed, is egg-shaped when viewed from the side and has a long, pointed beak . Two different spine shapes are formed on the 5 centimeter long and 3 centimeter wide fruits. The hook spines, up to 15 millimeters long, are about five in a row, and they do not go beyond the beak. The widened bases of the spines form a crest up to 4 millimeters high. The numerous simple spines are up to 2 millimeters long. No false partitions are formed. The triangular seeds are 8 millimeters long and 8 millimeters wide and have 2.5 millimeter wings.
