Rattan

Rattan (from the Malay rotan) is the name for roughly 600 species of old world climbing palms belonging to subfamily Calamoideae (from the Greek 'kálamos' = reed). Rattan is also known as manila, or malacca, named after the ports of shipment Manila and Malacca City, and as manau (from the Malay rotan manau, the trade name for Calamus manan canes in Southeast Asia). The climbing habit is associated with the characteristics of its woody stem, soft and flexible comparing to true wood derived from a typical secondary growth.

Calamoideae also includes tree palms such as Raphia (Raffia) and Metroxylon (Sago palm) and shrub palms such as Salacca (Salak) (Uhl & Dransfield 1987 Genera Palmarum). The climbing habit in palms is not restricted to Calamoideae, but has also evolved in three other evolutionary lines - Tribes Cocoeae (Desmoncus with c. 7-10 species in the New World tropics) and Areceae (Dypsis scandens in Madagascar) in subfamily Arecoideae, and Tribe Hyophorbeae (climbing species of the large genus Chamaedorea in Central America) in Subfamily Ceroxyloideae. They don't have spinose stems and climb by means of their reflexed terminal leaflets. Of these only Desmoncus spp. furnish stems of sufficiently good quality to be used as rattan cane substitutes.

There are 13 different genera of rattans that include around 600 species. Some of the species in these "rattan genera" have a different habit and do not climb, they are shrubby palms of the forest undergrowth; nevertheless they are close relatives to species that are climbers and they are hence included in the same genera. The largest rattan genus is Calamus, distributed in Asia except for one species represented in Africa. From the remaining rattan genera, Daemonorops, Ceratolobus, Korthalsia, , , Myrialepis, Calospatha, Pogonotium and Retispatha, are centered in Southeast Asia with outliers eastwards and northwards; and three are endemic to Africa: Laccosperma (syn. Ancistrophyllum), Eremospatha and Oncocalamus.
