Korthalsia
Sign in to saveKorthalsia is a clustering genus of flowering plant in the palm family Arecaceae spread throughout Southeast Asia. It is a highly specialized rattan with some species known to have an intimate relationship with ants, hence the common name ant rattan. High-climbing and armed with spines, the genus is named for the Dutch botanist Pieter Willem Korthals who first collected them in Indonesia.

Rotan dahan (nama saintifik "Korthalsia") merupakan nama umum bagi rotan dalam genus Korthalsia dalam kategori pokok Rotan. Genus ini dinamakan bersempena ahli botani Belanda P. W. Korthals yang merupakan orang pertama mengumpalnya dari Indonesia.[1] Pada pertengahan 1980-an kerajaan Malaysia telah menggalakkan penubuhan ladang hutan dan dengan itu ladang rotan telah dibuka di Semenanjung Malaysia, Sabah dan Sarawak oleh pelbagai Jabatan Perhutanan Negeri. Sehingga hari ini, perladangan rotan ini membantu ia daripada pupus dan menggalakkan industri perabut rotan di Malaysia. Berbeza dengan kebanyakan pokok palma, daun-daun pokok rotan tidak tumbuh berumpun menjadi silara; daun-daunnya mempunyai cangkuk yang panjang supaya memudahkan pokok-pokok rotan untuk memanjat ke silara pokok yang lain yang mempunyai panjang yang luar biasa (sering beberapa ratus kaki). Antara rotan dalam genus Kolthalsia adalah:- Kolthalsia echinometra Becc. Rotan udang, dahan, semut Kolthalsia flagellaris Miq. Rotan dahan Kolthalsia grandisRotan dahan Kolthalsia hispidaRotan semut Kolthalsia junghuhnii Miq.Rotan bulu Kolthalsia laciniosa Griff. ex Mart.Rotan merah Kolthalsia lanceolata J. Dransf.Rotan dahan

Korthalsia is a clustering genus of flowering plant in the palm family Arecaceae spread throughout Southeast Asia. It is a highly specialized rattan with some species known to have an intimate relationship with ants, hence the common name ant rattan. High-climbing and armed with spines, the genus is named for the Dutch botanist Pieter Willem Korthals who first collected them in Indonesia.
==Description== In young plants the trunks, petioles and rachises are covered in spines. Mature plants typically lose rachis and petiole spines but will retain trunks spines in its new growth. The suckering stems are small to mostly moderate and are among the few in the palm family that branch; among rattans it is the only one with splitting stems. These splits are axil branching, and produce "vast aerial entanglements" The trunks are bare at the bottom but retain persistent leaf bases in its youngest parts; enlarged paper-like appendages, ocreas, form where the petioles meet the stem. The ocreas are usually grossly swollen and house ants. Younger leaves are undivided with the occasional bifid apice. A truly pinnate leaf form comes in maturity and is accompanied by a barbed rachis extension which allows the palm to hook onto forest vegetation and climb to the canopy top where mature pinnae hang pendent. Also unique to the group are the rachis borne stalks, adapted for climbing, from which the leaflets emerge.
