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. [2]

Description

The palms now classified in this genus have uniting traits but are nonetheless diverse. Pleonanthy, monoecy, crownshafts, peduncular bracts, and the lack of armament characterize all members. The trunks may be solitary or suckering and may be diminutive to robust, spanning a range of heights. The leaves are pinnate and widely varied. The inflorescences are branched to three orders with both male and female flowers, some of which are beetle-pollinated. [3] The fruit may be ellipsoidal or spherical and colored yellow, orange, red, purple, or black when ripe, each with a single seed.

Taxonomy

The genus Hydriastele was first formally described in 1875 by Hermann Wendland and Carl Georg Oscar Drude in the journal Linnaea and the type species is Hydriastele wendlandiana . [4] The genus name is derived from Greek, combining "hydriad", a water nymph in mythology, and "column". [5]

Species list

The following is a list of Hydriastele species accepted by Plants of the World Online as at December 2022:

Distribution and habitat

Their known natural range includes a number of tropical settings in Sulawesi, the Maluku Islands, New Guinea, Australia, the Bismarck Archipelago, the Solomon Islands, New Hebrides, Fiji, and Palau. Very often they are found in rain forests of the montane and low lying varieties or upon ultrabasic rock, limestone ridges and serpentine faces.

Cultivation and uses

Several of these palms are cultivated and typically require conditions resembling those of their range. The trunks of some species are used as wall and floorboard components in house construction or split and fashioned into spears. [3]

<i>Ptychosperma</i> Genus of palms

Ptychosperma is a genus of flowering plant in the family Arecaceae. Most are native to Australia and/or New Guinea, with a few in the Solomon Islands and in Maluku Province of eastern Indonesia.

<i>Orania</i> (plant) Genus of palms

Orania is a genus of the palm tree family Arecaceae, and includes flowering plants native to Southeast Asia, Madagascar, and New Guinea.

Brassiophoenix is a monoecious genus of flowering plant in the palm family found in Papua New Guinea. Of the two similar species, one is more common in cultivation and was mistakenly identified as Brassiophoenix schumannii. In 1999, Zona and Estig showed that the commonly cultivated species was instead the type species Brassiophoenix drymophoeoides. The two species are distinguished by their separated geographical locations and minor differences in fruit form. The genus name is a combination of the surname Brass, honoring the first collector L.J. Brass, and Phoenix, another palm genus.

<i>Calyptrocalyx</i> Genus of palms

Calyptrocalyx is a monoecious genus of flowering plant in the palm family found in Papua New Guinea and the nearby Maluku Islands. Ranging from small to large, the palms in this genus are increasingly found in cultivation owing largely to their purple, red, and orange colored, new foliage. At least 26 species have been described while others, known only by local names, have not yet received a taxonomic account. Palms formerly classified within Paralinospadix have been incorporated into this genus. It is named from 2 Greek words meaning 'covered' and 'calyx'.

<i>Actinorhytis</i> Genus of palms

Actinorhytis is a monotypic genus of flowering plant in the palm family found in Oceania and southeast Asia. The lone species, Actinorhytis calapparia is a rain forest inhabitant and has very large fruit. The genus name is from two Greek words meaning 'ray' and 'fold' which describe the endosperm of the seed.

<i>Eleiodoxa</i> Genus of palms

Eleiodoxa is a monotypic genus of flowering plant in the palm family found in Southeast Asia. The only species, Eleiodoxa conferta, is a dioecious, swamp-dwelling plant, commonly called by Malay as asam kelubi or asam paya. While five species names have been published, the other four are usually recognized as synonyms of the lectotype E. conferta. The genus is named from two Greek words meaning "water" and "glory" and the species name is Latin for "congested", an allusion to the flower spike.

Eremospatha is a genus of climbing flowering plants in the palm family found in tropical Africa. These rattans are uncommon in cultivation and poorly understood by taxonomists;. Closely related to Laccosperma, they differentiated by the near complete absence of bracts and bracteoles. The name is from Greek meaning "without a spathe".

<i>Heterospathe</i> Genus of palms

Heterospathe is a monoecious genus of flowering plant in the palm family found in Oceania, where it is called sagisi palm. With 39 species, Heterospathe is named from a Greek combination of "various" and "spathe", which describes the two distinct bract types.

<i>Laccospadix</i> Genus of palms

Laccospadix is a monotypic genus of flowering plant in the palm endemic to Queensland. Only one species is known, Laccospadix australasicus, commonly called Atherton palm or Queensland kentia. The two Greek words from which it is named translate to "reservoir" and "spadix".

<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>Mauritiella</i> Genus of palms

Mauritiella is a dioecious genus of flowering plant in the palm family found in South America where it is commonly called buriti. It is named after the similar and closely related genus Mauritia.

Nenga is a monoecious genus of flowering plant in the palm family. It is native to Southeast Asia and commonly called pinang palm. N. gajah is the aberration in the genus with its short internodes, marcescent leaves and interfoliar inflorescence, a combination of traits seen in a few species of the closely related Pinanga and Areca palms. The genus name is based on a corruption of a Javanese term for a plant now classified within Pinanga.

<i>Ptychococcus</i> Genus of palms

Ptychococcus is a monoecious genus of flowering plant in the palm family from New Guinea and the Solomon Islands. They are closely related to Ptychosperma, only differentiated by the seed shape and endocarp type. The name is a combination of the Greek for "fold" and the Latin for "berry".

<i>Sciaphila</i> Genus of flowering plants

Sciaphila is a genus of mycoheterotrophic plants in the family Triuridaceae. These plants receive nutrition from fungi and neighboring trees and have less need for photosynthesis. It is widespread in tropical and subtropical regions, found in Africa, China, Japan, the Indian Subcontinent, Southeast Asia, Latin America and on various islands Pacific Islands.

<i>Hydriastele wendlandiana</i> Species of palm native to Australia and New Guinea

Hydriastele wendlandiana, commonly known as Wendland's palm, cat o' nine tails, creek palm or kentia palm, 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.
