SummaryRecent botanical exploration in eastern Malesia has resulted in the discovery of three spectacular palm taxa that have proved difficult to assign to genus. New evidence from molecular phylogenetic research indicates that these taxa should now be recognised as three monotypic genera. Here, we describe these genera as new to science, all of which are members of subtribe Ptychospermatinae (Areceae: Arecoideae). Jailoloa Heatubun & W. J. Baker is restricted to ultramafic vegetation in a… 
A Floristic Study of Halmahera, Indonesia Focusing on Palms (Arecaceae) and Their Seed Dispersal
The dispersal services of frugivores affect plant community assembly, persistence, and gene flow in the short-term, and in the long-term are critical to ensuring that tropical trees and palms can regenerate in disturbed areas and can migrate amidst climate change.
Beyond Genera Palmarum: progress and prospects in palm systematics
It is concluded that palm systematic knowledge is far from complete and that tools, such as GP2, only stimulate further scientific research and discovery, so many aspects of the palm Tree of Life still remain scarcely known.
More new rattans from New Guinea and the Solomon Islands ( Calamus , Arecaceae)
The palm flora of New Guinea now includes 62 species of Calamus, 34 of which have been described since 2002, demonstrating the remarkable scale of botanical discovery on the island.
Naming the chaos: generic redelimitation in Schismatoglottideae (Araceae)
Phylogenetic relationships within Araceae tribe Schismatoglottideae are elucidated based on nuclear ITS and plastid matK and all necessary nomenclatural changes are made including a new generic name, Vesta to replace Hestia, which has been discovered to be preoccupied by HESTia, a fossil lycopsid.
Plant Species Composition and Their Conspecific Association in Natural Tropical Rainforest, South Papua
Describing species of plant life-forms and described conspecific associations between small individuals and large individuals in natural tropical rainforest of Boven Digoel Regency, Papua revealed that three are large plant species grow along with their small individuals.
Global ex situ Conservation of Palms: Living Treasures for Research and Education
Under the old taxon Principes, palms were once the Princes of the Kingdom Plantae. First on Engler’s list, they occupy a cherished place to botanists, and remain treasured centerpieces of many
A genus‐level phylogenetic linear sequence of monocots
The sequence is provided in a numbered list of each of the 1225 genera in 75 monocot families, together with a complementary alphabetical list, which represents a standardized tool for the organisation ofmonocot herbarium collections.
Fruit colour and range size interact to influence diversification
How fruit traits alter dispersal patterns and how that, in turn, influences diversification is revealed, and striking differences in diversification rate within each range size category between fruit color groups are found.


Lanonia (Arecaceae: Palmae), a New Genus from Asia, with a Revision of the Species
A highly supported group of species is resolved separately from Licuala and the rest of the Livistoninae, and is closely related to Johannesteijsmannia, requiring that the segregate group be placed in a new genus, Lanonia.
Dransfieldia (Arecaceae)—A New Palm Genus from Western New Guinea
Abstract The systematic placement of the little-known species Ptychosperma micranthum (Arecaceae/Palmae: Arecoideae: Areceae) from far western New Guinea has been repeatedly disputed, resulting in
A monograph of the betel nut palms (Areca: Arecaceae) of East Malesia
The palm genus Areca is widespread in tropical Asia and includes the economically important betel nut palm, A. catechu. The genus has three centres of high species diversity: the Sunda Region, the
Molecular phylogenetics of the palm subtribe Ptychospermatinae (Arecaceae).
The phylogenetic hypothesis suggests that the Ptychospermatinae diverged into six major clades with repeated radiations into Australia and the western Pacific.
Evolution of stamen number in Ptychospermatinae (Arecaceae): insights from a new molecular phylogeny of the subtribe.
Phylogenetic relationships among arecoid palms (Arecaceae: Arecoideae).
New data sources are required to elucidate ambiguities that remain in phylogenetic relationships among and within the major groups of Arecoideae, as well as within the Areceae, the largest tribe in the palm family.
A synopsis of the genus Hydriastele (Arecaceae).
The four genera of palm genera in subtribe Arecinae are reduced to a single, more broadly defined genus, Hydriastele, and the rather uniform morphology of the group supports this taxonomic change.
A new subfamily classification of the palm family (Arecaceae): evidence from plastid DNA phylogeny
A new subfamilial classification of the palms is established, in which five subfamilies are recognized, rather than the six that were included in the previous classification, and critical basal nodes are now fully resolved and, in most cases, strongly supported.
A revision of Licuala (Arecaceae, Coryphoideae) in Borneo

  • 2012
An account of Licuala Wurmb in Borneo is presented based on herbarium studies and the author’s own fieldwork, finding 46 species, 26 of which are new species and a further two are new varieties.
New rattans from New Guinea ( Calamus , Arecaceae)
Although many appear to be rather rare, several are widespread, common species and some are of considerable use to local people, highlighting the need for further studies of palms in eastern Malesia, especially New Guinea.
