Hymenodictyon is a genus of flowering plants in the family Rubiaceae. It has about 30 species.Hymenodictyon At: World Checklist of Rubiaceae At: Kew Gardens Website. (see External links below). All are native to the Old World. The wood of Hymenodictyon orixense is soft and has limited use, mostly for boxes.David J. Mabberley. 2008. Mabberley's Plant-Book third edition (2008). Cambridge University Press: UK. The type species for Hymenodictyon is Hymenodictyon orixense (synonym: Hymenodictyon excelsum).Hymenodictyon In: Index Nominum Genericorum. In: Regnum Vegetabile (see External links below).David J. Mabberley. 1982. Hymenodictyon orixense, page 66. In: "William Roxburgh's 'Botanical description of a new species of Swietenia (Mahogany)' and other overlooked binomials in 36 vascular plant families". Taxon 31(1):65-73.
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.Hymenodictyon In: International Plant Names Index. (see External links below).Nathaniel Wallich. 1824. Flora Indica; or Descriptions of Indian Plants 2:148. The Mission Press. Serampore, India. (see External links below) The generic name is derived from two Greek words, hymen, "membrane", and diktyon, "net". It refers to the wing that surrounds each seed.Umberto Quattrocchi. 2000. CRC World Dictionary of Plant Names volume II. CRC Press: Boca Raton; New York; Washington, DC, USA. London, UK. (vol. II). (see External links below).
Molecular phylogenetic studies have shown that Hymenodictyon is paraphyletic over the Madagascan genus Paracorynanthe.Ulrika Manns and Birgitta Bremer. 2010. "Towards a better understanding of intertribal relationships and stable tribal delimitations within Cinchonoideae s.s. (Rubiaceae)". Molecular Phylogenetics and Evolution 56(1):21-39.
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.
