Balfour in his Botany of Socotra (Bayley Balfour, 1888) has a record of an Entada sp. No specimen can be traced and the identity of his plant is a mystery. He notes this as a "A beautiful and graceful tree of which material is too fragmentary to permit identification, [which] is provisionally referred to this genus". He goes on to say that it has some resemblance to Acacia pennivenia Schweinf. and that the inhabitants give it the same name (Tomhor). No species of Entada has been recorded from the island and it seems likely that Balfour’s plant was in fact Acacia pennivenia.
