Umdhlebi Tree of Zululand

Umdhlebi Tree is a cryptobotanical poisonous tree that reputedly grows in southern Africa, described by G.W. Parker as having leaves that are "lanceolate, dark green, glossy, hard, and brittle," and producing a "thick milky juice," as well as fruit "like a long black pod, red at the end." Notably, the tree (and related shrub) has the "power of poisoning any living creature which approaches it; the symptoms of poisoning by it being severe headache, blood-shot eyes, and delirium, ending in death."
