Adina is a genus of 12 species of flowering plants in the family Rubiaceae. They are shrubs or small trees, native to East Asia and Southeast Asia.
Description Adina is a genus of shrubs and small trees. The terminal vegetative buds are inconspicuous and loosely surrounded by the stipules. The stipules are bifid for at least 2/3 of their length. The corolla lobes are nearly valvate in bud, being subimbricate at the apex. The anthers are basifixed and introrse. The ovary has two locules, with up to four ovules per locule.
Taxonomy Adina was named by Richard Salisbury in 1807 in his book, The Paradisus Londinensis. The genus name is derived from the Ancient Greek word , meaning "clustered, crowded". It refers to the tightly clustered heads of flowers. The biological type for Adina consists of the specimens that Salisbury called Adina globiflora.Adina In: Index Nominum Genericorum. In: Regnum Vegetabile. These are now included in the species Adina pilulifera. Molecular phylogenetic studies have shown that Adina is paraphyletic over Adinauclea, a monospecific genus from Sulawesi and the Moluccas.
