Hydriastele
''Hydriastele'' is a diverse and widespread genus of flowering plant in the palm family found throughout Australia and New Zealand, 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. 48 species are now recognized, of which 38 are new combinations, two are new names and one is a new species. It is named in Greek, combining "hydriad", a water nymph in mythology, and "column".〔Riffle, Robert L. and Craft, Paul (2003) ''An Encyclopedia of Cultivated Palms''. Portland: Timber Press.

==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.〔Uhl, Natalie W. and Dransfield, John (1987) ''Genera Palmarum - A classification of palms based on the work of Harold E. Moore''. Lawrence, Kansas: Allen Press. ISBN 0-935868-30-5 / ISBN 978-0-935868-30-2〕 The fruit may be ellipsoidal or spherical and colored yellow, orange, red, purple, or black when ripe, each with a single seed.
