Trachycarpeae is a tribe of palms in subfamily Coryphoideae of the plant family Arecaceae.
[1][2] It has the widest distribution of any tribe in Coryphoideae and is found on all continents (except Antarctica), though the greatest concentration of species is in Southeast Asia.
[4] Several genera can be found in cultivation in temperate areas, for example species of Trachycarpus, Chamaerops, Rhapidophyllum and Washingtonia.
[5] Palms in this tribe have palmate leaves with induplicate folds (reduplicate in Guihaia).
[3] Plants may be tall, single-stemmed trees (e.g. Copernicia, Brahea, Pritchardia), acaulescent with short, squat trunks (e.g. Maxburretia, Johannesteijsmannia), multi-stemmed (e.g. Rhapis, Acoelorraphe) or branched and prostrate (e.g. Serenoa).
These palms flower regularly throughout their lives (pleonanthic) and may be dioecious, monoecious or hermaphroditic.
[6] The tribe is monophyletic, but phylogenetic studies have yet to reveal its closest relatives, though they could be the Phoeniceae, or the Sabaleae and Cryosophileae.
Several genera in this tribe have yet to be allocated to a subtribe, due to a lack of convincing data from phylogenetic studies.
