***Alyxia*** is a genus of [flowering plants](/source/Flowering_plant) in the family, [Apocynaceae](/source/Apocynaceae). It contains at present[when?] 106 species, but *[Alyxia stellata](/source/Alyxia_stellata)* and *[A. tisserantii](/source/Alyxia_tisserantii)* are very variable, might be [cryptic species complexes](/source/Cryptic_species_complex), and are need of further study. It consists of shrubby, climbing or scrambling plants. This genus occurs in [China](/source/China), the [Himalayas](/source/Himalayas), [Southeast Asia](/source/Southeast_Asia), [Australia](/source/Australia), [New Caledonia](/source/New_Caledonia) and the [Pacific Islands](/source/Pacific_Island). There are 14 species in Australia, 21 in New Caledonia and 7 in the other Pacific Islands, including [Hawaii](/source/Hawaii).[2][full citation needed]

The [leaves](/source/Leaf) are opposite or in whorls of three to seven. There are [colleters](/source/Colleter_(botany)) (groups or tufts of mucilaginous secretory hairs) present in the leaf axils. The [inflorescence](/source/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 filaments and are inserted in the upper half of the corolla. The fruit is a pair of [drupes](/source/Drupe), originating from each flower.[2][full citation needed]

[Dysentery bush](/source/Alyxia_buxifolia) (*[A. buxifolia](/source/Alyxia_buxifolia)*) is used in [herbalism](/source/Herbalism) and was made into a patented remedy by [Albert Aspinall](/source/Albert_Aspinall). *[Maile](/source/Maile)* (*A. oliviformis*), [endemic](/source/Endemism) to the Hawaiian Islands, has sweet-smelling leaves and is much used for [lei](/source/Lei_(Hawaii)); formerly it was reserved for *[alii](/source/Ali'i)* (nobility), but today it can be used by anyone and is a popular wedding decoration on the islands. *Maile* also provides food for *[Thyrocopa](/source/Thyrocopa)* caterpillars and weevils of the genus *[Proterhinus](/source/Proterhinus)*. Alyxia spp. are also used in [Jamu](/source/Jamu).[citation needed]
