The Malesian species of five relatively unknown Euphorbiaceous genera are redescribed. Alphandia , Borneodendron , Cladogynos and Tapoides , each with one species in Malesia, are part of the Euphorbiaceae in the strict sense; Ashtonia (two species) is presently classified in the Phyllanthaceae. The descriptions have been completed by studying extra material, and high quality drawings are added.

TLDR
During the environmental impact study for a proposed nickel mine near Weda Bay on Halmahera in North Moluccas, Indonesia, two unknown Euphorbiaceae were discovered and indicated that they should be recognized as constituting a new, distinct genus of two species, which are described and illustrated here as Weda fragarioides and Weda lutea.

Synopsis of the Genera and Suprageneric Taxa of Euphorbiaceae
TLDR
This revised synopsis of the taxa of Euphorbiaceae recognizes, and provides keys to, 5 subfamilies, 49 tribes, and 317 genera, and proposes two new tribes and four new subtribes.

TLDR
Two new species of Trigonostemon in Sumatra and East Borneo and a remarkable new Alchornea from Siam are described.
Molecular phylogenetic analysis of Phyllanthaceae (Phyllanthoideae pro parte, Euphorbiaceae sensu lato) using plastid RBCL DNA sequences.
TLDR
Analysis of plastid rbcL DNA sequence data of the pantropical family Phyllanthaceae and related biovulate lineages of Euphorbiaceae sensu lato is presented and Antidesma, Bischofia, Hymenocardia, Martretia, and Uapaca, all of which have previously been placed in monogeneric families, are confirmed as members of PhyllAnthaceae.

TLDR
A Paspalum (nr. 155; W) was collected on April 1887 and the date 1857 seems erroneous.
