Kigelia africana

Overview

The botanical account describes a spreading crown, leathery foliage and grey-brown fruits on long stalks. Dark red, wrinkled trumpet flowers contain nectar. The separate illustrated organs are conceptual studies, not specimens collected together.

A Kruger National Park study combined riverbank surveys, flower treatments, cameras and seedling plots. Experimental selfing produced no fruit, supporting obligate out-crossing in the tested trees. Birds were the principal observed pollinators; anticipated bat visits were not observed there.

The sampled population was dominated by large trees. High seed availability did not explain the scarcity of recruits; dispersal limitations and seedling herbivory were considered. These proposed bottlenecks are local research interpretations, not a demonstrated extinction mechanism throughout Africa.

Origins & earliest records

The account combines a botanical-garden description with a 2019 study of Kruger reproductive ecology.

Evidence & interpretation

The primary paper retains methods and results; the botanical account describes the fruit, flowers and foliage.
