Calamus draco is an Asian species of rattan plant in the family Arecaceae; its native range is from peninsular Thailand to western Malesia. [1] [2] It is a source of the red resin known as dragon's blood, which is a pigment with medicinal uses. [3]

Description

Calamus draco has stems in clusters forming individual rattan stems climbing up to 15 m., with sheaths to 30 mm diameter. Leaf fronds are described as cirrate (with a cirrus: extension of the rattan leaf tip armed with grappling hooks), produced from leaf-sheaths, which are bright green, bearing chocolate-coloured indumentum when young: they are 2.5 m long including petiole (up to 300 mm and armed with groups of short lateral spines to 6 mm long); the cirrus is about 1 m long. About 20 regularly arranged leaflets are on each side of the rachis. The mature fruit are more or less ovoid, 28 x 20 mm, covered in 16 vertical rows of scales and may be heavily encrusted with the "dragon's blood". [2]

Rattan, also spelled ratan, is the name for roughly 600 species of Old World climbing palms belonging to subfamily Calamoideae. The greatest diversity of rattan palm species and genera are in the closed-canopy old-growth tropical forests of Southeast Asia, though they can also be found in other parts of tropical Asia and Africa. Most rattan palms are ecologically considered lianas due to their climbing habits, unlike other palm species. A few species also have tree-like or shrub-like habits.

<span class="mw-page-title-main">Dragon's blood</span> Bright red plant-based resin

Dragon's blood is a bright red resin which is obtained from different species of a number of distinct plant genera: Calamus spp. also including Calamus rotang, Croton, Dracaena and Pterocarpus. The red resin has been in continuous use since ancient times as varnish, medicine, incense, pigment, and dye.

<i>Dracaena draco</i> Species of plant

Dracaena draco, the Canary Islands dragon tree or drago, is a subtropical tree in the genus Dracaena, native to the Canary Islands, Cape Verde, Madeira, western Morocco, and possibly also in the Azores.

<i>Daemonorops</i> Historically recognized genus of palms

Daemonorops was a genus of rattan palms in the family Arecaceae. Its species are now included within the genus Calamus.

<i>Korthalsia</i> Genus of palms

Korthalsia is a clustering genus of flowering plant in the palm family 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 P. W. Korthals who first collected them from Indonesia.

<i>Myrialepis</i> Genus of palms

Myrialepis is a monotypic genus of flowering plant in the palm family. The single species, Myrialepis paradoxa, is native to Southeast Asia. The genus name is a combination of the Greek words meaning "innumerable" and "scale", a description of the fruit, and the epithet is Latin for "paradox".

<i>Ceratolobus</i> Genus of palms

Ceratolobus was a dioecious genus of flowering plants in the palm family found in Southeast Asia, commonly called rotan. Its species are now included within the genus Calamus. They are only differentiated from close relatives like Korthalsia, Calamus, and Daemonorops by leaf sheath appendages or inflorescence variations. The Greek genus name combines "horn" and "capsule".

Plectocomiopsis is a dioecious genus of flowering plant in the palm family found in Indochina, Malaysia, Borneo and Sumatra. Hapaxanthic and armed with spines, they are a climbing rattan, closely related to the Myrialepis palms. The name is Greek for "similar to Plectocomia", another close relative.

Pogonotium was a dioecious genus of flowering plant in the palm family found in Malaysia and Borneo. Its species are now included within the genus Calamus. Its close relatives are climbing rattans and while partially armed with climbing apparatus, its habit is sprawling and leaning but not effective climbing. The reduced inflorescence nestled between the auricles is unusual and distinguishes it from similar relatives like Calamus, Daemonorops and Ceratolobus. The name is Greek meaning "bearded".

<i>Calamus rotang</i> Species of palm

Calamus rotang, also known as common rattan, is a plant species native to India, Sri Lanka and Myanmar (Burma). It is one of the scandent (climbing) rattan palms used to make Malacca cane furniture, baskets, walking-sticks, umbrellas, tables and general wickerwork, and is found in Southwest Asia. The basal section of the plant grows vertically for 10 metres or so, after which the slender, tough stem of a few centimetres in diameter, grows horizontally for 200 metres or more. It is extremely flexible and uniform in thickness, and frequently has sheaths and petioles armed with backward-facing spines which enable it to scramble over other plants. It has pinnate, alternate leaves, 60–80 cm long, armed with two rows of spines on the upper face.

<span class="mw-page-title-main">Calamus australis</span> Species of palm plant

Calamus australis, commonly known as wait-a-while, hairy mary or lawyer cane, is a plant in the palm family Arecaceae which is endemic to the rainforests of north east Queensland, Australia. Like other species in the genus Calamus, this is a climbing plant with a very long and flexible stem. It uses sharp strong hooks on the fronds and tendrils to attach itself to other vegetation, such as taller established trees, thus gaining support that enables it to grow higher towards the canopy. This species is very similar to C. radicalis, with which it coexists, but is smaller in almost all respects.

<i>Calamus muelleri</i> Species of climbing palm native to Australia

Calamus muelleri, commonly known as southern lawyer cane or wait-a-while, is a climbing palm with a vine-like habit, endemic to the subtropical coastal rainforests of northern New South Wales and southern Queensland. Sharp hooks on the plant can snag the clothing of walkers in these forests, giving rise to the name "wait-a-while".

<span class="mw-page-title-main">Calamoideae</span> Subfamily of palms

Calamoideae is a subfamily of flowering plant in the palm family found throughout Central America, South America, Africa, India, China, Southeast Asia and Australia. It is represented by 21 genera - containing nearly a quarter of all species in the palm family - including the largest genus, Calamus, the type genus of the group. Only four are found in the New World while the rest are Old World denizens, usually found in equatorial swampland or along tropical coastlines.
