“…A further species from the highlands of Papua, Hydriastele rheophytica, was added to this group by Dowe & Ferrero (2000). Subsequently, the molecular phylogenetic analysis of Loo et al (2006) led to a substantial expansion of the generic limits of Hydriastele. Their study revealed that Hydriastele sensu Burret (1937) is monophyletic, but embedded within a larger paraphyletic group of three closely related genera, Gronophyllum Scheff., Gulubia Becc.…”

“…NOTES. Hydriastele apetiolata is known from three collections, all of which were sequenced for two genes by Loo et al (2006) along with other specimens belonging to the Hydriastele wendlandiana group. In the resulting phylogenetic trees, H. apetiolata is distinguished by consistently falling outside of a wellsupported clade containing all other members of the group that were included in the study.…”

“…The monophyly of Hydriastele is well supported, as is its placement in the major Indo-Pacific tribe Areceae, but current molecular evidence is insufficient to place the genus to subtribe (Loo et al 2006;Dransfield et al 2008;Baker et al 2009;Baker et al 2011;Baker & Dransfield 2016). The phylogenetic relationships among the species of Hydriastele have been explored (Loo et al 2006).…”

“…The phylogenetic relationships among the species of Hydriastele have been explored (Loo et al 2006). Here, we present a monograph of an infrageneric species grouping within Hydriastele, a monophyletic group identified by Loo et al (2006) that we term Hydriastele wendlandiana group. It occurs in New Guinea, the Bismarck Archipelago, northern Australia, and immediately adjacent islands, and is distinguished from the rest of the genus by its slender to moderate growth habit combined with protogynous inflorescences in which the stigmas are congenitally exposed (i.e.…”

Summary.A taxonomic revision is presented of the Hydriastele wendlandiana group, a well-defined species grouping within the Indo-Pacific palm genus Hydriastele that occurs in New Guinea, the Bismarck Archipelago and northern Australia. We accept five species: Hydriastele kasesa, H. rheophytica, H. variabilis, H. wendlandiana and H. apetiolata sp. nov. and provide fundamental information about each of those taxa including a summary of the group's taxonomic history and phylogeny, a distribution map, a key to the species, species descriptions with scientific illustrations, and IUCN Red List assessments.

Phylogeny and evolution of morphological characters in tribe Chamaedoreeae (Arecaceae)

Within the palm family, molecular analyses have resulted in a need to reevaluate characters previously considered useful to establish hypotheses of relationships among groups. Recent phylogenetic analyses of tribe Chamaedoreeae have shown that characters traditionally used as strong indicators of relationship, such as presence of solitary flowers and dioecy, are homoplasious within this tribe. In the largest genus, Chamaedorea, published molecular analyses recover wellsupported groups not previously proposed based on morphological characters and at the same time resolve some of the current subgenera as polyphyletic. In this study we further explore the phylogenetic relationships in Chamaedoreeae and search for morphological synapomorphies for the monophyletic groups recovered. Phylogenetic analyses of morphological, nuclear (PRK, RPB2), and plastid (matK, ndhF, trnDtrnT, rps16 intron, trnLtrnF) data are performed and morphological characters are subsequently optimized on the resulting topologies. Although most of the morphological characters included are highly homoplasious, the inclusion of morphological characters in the phylogenetic analyses improves the resolution within Chamaedoreeae, particularly among species of Chamaedorea. With the exception of Synechanthus and Wendlandiella, all the genera and subgenera in Chamaedoreeae are defined by a combination of homoplasious characters, none of which is unique within the tribe. Two of the seven subgenera of Chamaedorea included in our analyses, C. subg. Eleutheropetalum and subg. Stephanostachys, are supported as monophyletic with a number of morphological synapomorphies also used in the original descriptions of these subgenera. Some morphological characters not used in the traditional subgeneric classification of Chamaedorea, such as leaf sheath structure and pistillode, gynoecium and filament connation, though homoplasious, are resolved as synapomorphies and, therefore, potentially useful when defining subgenera within this genus.

† Background With more than 90 published studies of pollination mechanisms, the palm family is one of the better studied tropical families of angiosperms. Understanding palm-pollinator interactions has implications for tropical silviculture, agroforestry and horticulture, as well as for our understanding of palm evolution and diversification. We review the rich literature on pollination mechanisms in palms that has appeared since the last review of palm pollination studies was published 25 years ago. † Scope and Conclusions Visitors to palm inflorescences are attracted by rewards such as food, shelter and oviposition sites. The interaction between the palm and its visiting fauna represents a trade-off between the services provided by the potential pollinators and the antagonistic activities of other insect visitors. Evidence suggests that beetles constitute the most important group of pollinators in palms, followed by bees and flies. Occasional pollinators include mammals (e.g. bats and marsupials) and even crabs. Comparative studies of palm-pollinator interactions in closely related palm species document transitions in floral morphology, phenology and anatomy correlated with shifts in pollination vectors. Synecological studies show that asynchronous flowering and partitioning of pollinator guilds may be important regulators of gene flow between closely related sympatric taxa and potential drivers of speciation processes. Studies of larger plant-pollinator networks point out the importance of competition for pollinators between palms and other flowering plants and document how the insect communities in tropical forest canopies probably influence the reproductive success of palms. However, published studies have a strong geographical bias towards the South American region and a taxonomic bias towards the tribe Cocoseae. Future studies should try to correct this imbalance to provide a more representative picture of pollination mechanisms and their evolutionary implications across the entire family.
