'''''Alyxia''''' is an [[Australasia]]n genus with 106 species from the Dogbane family ([[Apocynaceae]]). It consists of shrubs, climbers or scramblers (a plant with long stems, often with thorns to help it support itself as it climbs through shrubs).
This genus occurs in [[China]], the [[Himalayas]], SE [[Asia]], [[Malaysia]], [[Australia]], [[New Caledonia]] and the [[Pacific]] Islands. There are 14 species in Australia, 21 in New Caledonia and 7 in the other Pacific Islands, including [[Hawaii]].
The [[Leaf|leaves]] are opposite or in whorls of three to seven. There are colleters present in the leaf axils, i.e. a group or tuft of mucilaginous secretory hairs.
The [[inflorescence]] is axillary or terminal with solitary flowers or simple cymes. Flowers consist of five petals and five sepals. The flowers have a slender tube which expands abruptly. The stamens have short filamens and are inserted in the upper half of the corolla. The fruit is a pair of [[drupe]]s, originating from each flower.
''Alyxia stellata'' and ''Alyxia tisserantii'' are variable species and need of further study.
