Hymenodictyon is a genus of flowering plants in the family Rubiaceae. It has about 30 species.[1] All are native to the Old World. The wood of Hymenodictyon orixense is soft and has limited use, mostly for boxes.[2] The type species for Hymenodictyon is Hymenodictyon orixense (synonym: Hymenodictyon excelsum).[3][4]

Hymenodictyon was named by Nathaniel Wallich in 1824 in an addendum to William Roxburgh's Flora Indica, in an edition published by Carey and Wallich after Roxburgh's death.[5][6] The generic name is derived from two Greek words, hymen, "membrane", and diktyon, "net". It refers to the wing that surrounds each seed.[7]

Molecular phylogenetic studies have shown that Hymenodictyon is paraphyletic over the Madagascar genus Paracorynanthe.[8]

In Hymenodictyon and Paracorynanthe, the stipules bear large deciduous glands called colleters. The corolla tube is narrow at the base, gradually widening toward the apex. The fruit is a woody capsule.
