Dendrosicyos

Dendrosicyos is a genus of flowering plant in the Cucurbitaceae family. It consists of one species, Dendrosicyos socotranus (cucumber tree), which is native to Socotra, Yemen.

It was first described by Isaac Bayley Balfour in 1882. Recent molecular phylogenetic analysis of the Cucurbitaceae found that the lineage of Dendrocisyos is about twice as old as Socotra, and thus seems to be an island relict or a progenitor lineage that became extinct on the mainland.
