“…Notes : The publication of any new palm genus is a significant event, but the simultaneous description of three new genera is unprecedented in recent decades (Heatubun et al ., , c). Jailoloa , Manjekia and Wallaceodoxa Heatubun & W.J.Baker were described as a result of fieldwork in eastern Indonesia led by Charlie Heatubun and William Baker to smaller islands to the north and west of the western end of New Guinea.…”

The systematic biology of the palm family (Arecaceae) is probably better known than that of any other tropical plant family of comparable size. As a result, the palms are now regarded as a model group for tropical rain forest research. Ten years ago, the first phylogenetic classification of palms was established as a foundation for the second edition of the palm systematic synthesis, Genera Palmarum (GP2), which was published in 2008. Here, we review progress in palm systematics since GP2, summarizing the latest developments in an updated palm classification and schematic phylogenetic tree. To date, the palms comprise 181 genera and c. 2600 species. In just 8 years, six new genera and 200 new species have been described, whereas eight genera have been sunk into synonymy. This reflects the highly dynamic nature of systematic discovery of palms at both forest and phylogenetic frontiers. Palm phylogenetics is a vibrant field, with new trees being generated and utilized in increasingly innovative and ambitious ways. Existing understanding of relationships among the five subfamilies has been confirmed and deep nodes in the subfamilies are crystallizing, especially in subfamilies Arecoideae and Coryphoideae. We conclude that palm systematic knowledge is far from complete and that tools, such as GP2, only stimulate further scientific research and discovery. Despite recent advances, however, many aspects of the palm Tree of Life still remain scarcely known. The vast datasets that the phylogenomic revolution is now bringing to bear on palms promise to elucidate many of these unknowns. The ultimate goal, a species-level phylogenetic tree for palms, is now coming within reach.

“…One of the best studied groups are the palms (Palmae or Arecaceae). Although there is no overview of palm biogeography for Papua, the palm flora of Biak has been studied by Baker & Heatubun (2012 (Heatubun et al 2014). Undoubtedly, additional Biak-endemic plant species will be discovered as the botanical knowledge of Papua increases.…”

A review of new data relating to Nepenthes insignis in Indonesia indicates that three taxa in section Insignes, not one, are present in New Guinea. One of these, endemic to the limestone of the island of Biak, is formally named as Nepenthes biak and assessed as Critically Endangered; the other, from limestone of the Raja Ampat islands is provisionally distinguished as Nepenthes sp. Raja Ampat, since only images are available.

“…On current data, another point endemic in the area, which is also assessed as Critically Endangered is Jailoloa halmaherensis (Heatubun) Heatubun & W.J. Baker, a species representing a monotypic palm genus restricted to Gunung Batu, several kilometres to the NE of Bukit Limber, outside of the Weda Bay Nickel Project, in the neighbouring Nickel Mining concession area of Pt Buena Persada (Solway International) (Heatubun et al 2014). …”

Two new paniculate species of Nepenthes, N. halmahera and N. weda, both allied to N. danseri Jebb & Cheek, are described respectively from lowland and lower montane forest on ultramafic substrate. Nepenthes weda appears to be unique in the genus due to the adaxial tepal surfaces which in the distal portion are hairy and lack nectar glands. This species is also unique among paniculate members of the genus in its forward-facing, concave subapical lid appendage. Both species are currently only known from the Weda Bay Nickel Project concession area in Halmahera, Indonesia, and are assessed as Critically Endangered using the 2012 IUCN standard. Two character states are formally described and named for the first time in Nepenthes: nanophyll rosettes and multiseriate fringed pitcher wings. Stage-related heteromorphy in lid appendages is documented for the first time in the genus. Keys to the species of Nepenthes of Halmahera, and to the paniculate species of SE Asia are presented.
