Hydriastele wendlandiana, commonly known as Wendland's palm, [4] cat o' nine tails, creek palm [5] or kentia palm, [6] is a tall, multi-stemmed tree in the palm family Arecaceae. It is native to New Guinea and the Australian states of Queensland and the Northern Territory. [4] [7]

Description

H. wendlandiana grows to a height of 25 m (82 ft) with 3 to 7 stems up to 12 cm (4.7 in) in diameter. [4] [6] [8] The sparse crown has 5 to 10 paripinnate fronds measuring up to 2 m (6 ft 7 in) in length, with up to 20 praemorse pinnae (leaflets), on either side of the slightly arching rachis (midrib). [4] [6] [8] The leaflets are sessile and irregularly spaced, and may be up to 45 cm (18 in) long by 6 cm (2.4 in) wide, dark green on the upper surface and lighter below. The apical leaflets are merged at the base and are much broader than the rest. [6] [8]

The species is monoecious, that is, it has both staminate (functionally male) and pistillate (functionally female) flowers on the one plant. The inflorescence emerges from the trunk at the base of the crownshaft [5] and resembles a cat o' nine tails, having 10–20 straight spikes around 20 cm (7.9 in) long. The spikes are initially erect but become pendulous as the fruit develops. [4] [6] The flowers are arranged in groups of 3, with two staminate flowers either side of a pistillate flower. The staminate flowers are 4 mm (0.16 in) in diameter and 9 mm (0.35 in) long, the pistillate flowers are more or less conical to globose and up to 3 mm (0.12 in) in diameter. [4] [6] [8]

The fruits may be orange, purple or various shades of red. [8] They are ovoid to globose, about 10 mm (0.39 in) in diameter with a single 8 mm (0.31 in) globose seed. [6]

Taxonomy

The species was first described as Kentia wendlandiana in 1870 by the German-Australian botanist Ferdinand von Mueller in his work Fragmenta Phytographiae Australiae. Very shortly after, in 1875, it was renamed Hydriastele wendlandiana by Hermann Wendland and Oscar Drude, who erected the genus Hydriastele in the journal Linnaea. [8]

Etymology

The genus name Hydriastele derives from the Ancient Greek ὑδρο- (hudro-), meaning water, and στήλη (stḗlē), meaning column. It refers to the plant's preference for growing in or near swamps. [5] [9]

The species epithet wendlandiana is in honour of the German botanist Hermann Wendland who was a noted authority on Arecaceae. [5]

Distribution and habitat

Wendland's palm is found throughout New Guinea and the Aru Islands, and in the northernmost parts of the Northern Territory (from Bathurst Island, Melville Island and Croker Island, across the Top End to Groote Eylandt in the Gulf of Carpentaria), and then into Queensland from Cape York Peninsula down the east coast to Mission Beach, where it grows on various soil types in rainforest, monsoon forest and swamp forest, often in or close to swamps, at altitudes from sea level to 200 m (660 ft). [4] [6] [7]

Ecology

Fruits of Wendland's plam are eaten by fruit doves, metallic starlings and cassowaries. [5]

<i>Acanthophoenix</i> Genus of palms

Acanthophoenix is a genus of flowering plants in the palm family from the Mascarene Islands in the Indian Ocean, where they are commonly called palmiste rouge. A genus long in flux, three species are currently recognized, though unsustainable levels of harvesting for their edible palm hearts have brought them all to near extinction in habitat. They are closely related to the Tectiphiala and Deckenia genera, differing in the shape of the staminate flower. The name combines the Greek words for "thorn" and "date palm".

<i>Archontophoenix alexandrae</i> Species of palm endemic to Queensland

Archontophoenix alexandrae, commonly known as Alexandra palm, king palm, Northern Bangalow palm, or feather palm, is a palm endemic to Queensland, Australia. It was named in honour of Princess Alexandra of Denmark, but is often erroneously referred to by the misnomer Alexander palm.

<i>Archontophoenix</i> Genus of palms

Archontophoenix is a plant genus comprising six palm species that are native to New South Wales and Queensland in eastern Australia. They are tall, slender and unbranched. Relationships between Archontophoenix and the other genera of subtribe Archontophoenicinae, including the New Caledonia endemic Actinokentia, Chambeyronia and Kentiopsis are unresolved.

<i>Ptychosperma macarthurii</i> Species of palm native to northern Australia and New Guinea

Ptychosperma macarthurii, commonly known as the Macarthur palm, is a species of tree in the palm family Arecaceae. Its native range is northern Cape York Peninsula in Queensland with a number of disjunct populations in the Northern Territory and New Guinea. The species has been widely planted in tropical areas and is commonly grown as an indoor plant.

<i>Dictyosperma</i> Genus of palms

Dictyosperma is a monotypic genus of flowering plant in the palm family found in the Mascarene Islands in the Indian Ocean. The sole species, Dictyosperma album, is widely cultivated in the tropics but has been farmed to near extinction in its native habitat. It is commonly called princess palm or hurricane palm, the latter owing to its ability to withstand strong winds by easily shedding leaves. It is closely related to, and resembles, palms in the genus Archontophoenix. The genus is named from two Greek words meaning "net" and "seed" and the epithet is Latin for "white", the common color of the crownshaft at the top of the trunk.

<i>Hydriastele</i> Genus of palms

Hydriastele is a diverse and widespread genus of flowering plant in the palm family found throughout northern Australia, Melanesia, Polynesia, and Southeast Asia. It consisted of just nine species until 2004, when molecular research, supported by morphologic similarities, led taxonomists to include the members of the Gulubia, Gronophyllum, and Siphokentia genera. About 40 species are now recognized.

<i>Calamus australis</i> 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.

<i>Calamus moti</i> Species of climbing palm endemic to Queensland
