Calamus moti is a climbing rainforest plant in the palm family Arecaceae, which is endemic to Queensland. It has a slim flexible stem which does not support the plant, instead it climbs to the forest canopy with the assistance of long tendrils armed with stout recurved hooks.

Description

This is a clustering, climbing palm with stems up to 5 cm (2.0 in) in diameter and 45 m (148 ft) in length, making it the largest of the eight Calamus species found in Australia. [4] [5] The leaves are up to 3 m (10 ft) long and are pinnate with 35 to 50 leaflets either side of the rachis. The underside of the rachis has three longitudinal rows of stout recurved hooks. [4] [5] [6] The leaflets are linear-lanceolate, up to 60 cm (24 in) long by 3 cm (1.2 in) wide, with very fine barbs on their margins [5] [6] On the upper surface of each leaflet there are two longitudinal rows, one either side of the central vein, of spines measuring up to 10 mm (0.39 in) long.

The leaf sheaths completely surround the stem and are armed with stout yellow-green spines about 20 mm (0.79 in) long arranged in oblique combs. Flagella armed with stout recurved barbs are produced from the leaf sheath and act as grappling hooks providing support for the flexible stem. [4] [5]

On older sections of the stem the fronds and their leaf sheaths fall away, revealing the stem's smooth glossy green surface.

Taxonomy

Calamus moti was first described by Frederick Manson Bailey and published in 1896 in the journal Bulletin of the Department of Agriculture, Brisbane. [7]

Etymology

The genus name Calamus is derived from Ancient Greek κάλαμος (kálamos) and means reed or cane. The species epithet moti is the name for this plant in the language of the Djabugay people of the Barron River. [6] [7]

Distribution and habitat

C. moti is endemic to Queensland, ranging from near Cooktown southwards to around Mackay. It grows in well developed rainforest, reaching peak development when close to water courses, and it can be found at elevations from close to sea level to about 1,300 m (4,300 ft). [4] [5] [6] [8]

Ecology and uses

The yellow lawyer cane is the host plant for the white-fringed swift Sabera fuliginosa , a butterfly of the family Hesperiidae, and the fruits are eaten by birds.

Indigenous communities of north Queensland ate the fruits and the young shoots, while the cane from the stem was used for many purposes including axe handles, fish and animal traps, shelters and baskets. [9]

Conservation

This species is listed by the Queensland Department of Environment and Science as least concern. [1] As of 8 April 2022, it has not been assessed by the IUCN.

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.

The species has been widely planted in tropical areas and is commonly grown as an indoor plant.

<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>Laccosperma</i> Genus of palms from Africa

Laccosperma is a clustering genus of flowering plant in the family palm found in tropical Africa. Poorly studied and rarely cultivated, they are closely related to the genus Eremospatha and with it form a tribe in the Calameae characterized by dyads of hermaphrodite flowers. The genus name combines the Greek words for "reservoir" and "seed".

<i>Myrialepis</i> Genus of palms

Myrialepis is a monotypic genus of flowering plant in the palm family, the single species, Myrialepis paradoxa, 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".

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.
