A revision of all species of the genus Cinnamomum Schaeff. (Lauraceae) occurring in Peninsular Malaysia and Singapore is presented with a summary of taxonomic history, notable features of morphology, a key to species, and a description, distribution map, Provisional IUCN Conservation Assessment for each species, together with notes on ecology and ethnobotany. In this revision, twenty-two distinct species are recognised, including one former variety that is elevated to species level as Cinnamomum selangorense (Ridl.) de Kok. Eleven names are lectotypified (Camphora inuncta Nees; Cinnamomum cinereum Gamble, C. graciliflorum Gamble, C. malaccense Meisn., C. ridleyi Gamble, C. rhynchophyllum Miq., C. sintoc Blume, C. subcuneatum Miq., C. velutinum Ridl., and C. vimineum Wall. ex Nees; Laurus malabathrum Wall. ex Nees), and five names are placed into synonymy for the first time. A small number of species are considered to have a Provisional IUCN Conservation Assessment of Least Concern, while most are either Endangered or Critically Endangered, with one species considered to be Data Deficient (Cinnamomum trintaense Kosterm.).

Cuticular features potentially offer valuable information on phytotaxonomy, especially for plants that are difficult to classify or identify. Cryptocarya is one such difficult and poorly known genus, and we investigated its cuticular features to evaluate their taxonomic implications. We examined cutinized leaf epidermis and the stomatal complex for 21 species from Peninsular Malaysia, Thailand and Indo-China, as well as one species endemic to Borneo and one to Sumatra, and compared features among members of this group, between this group and congeners in the other countries, and between this group and the other genera of Lauraceae. Many of the Cryptocarya species studied have straight to slightly curved anticlinal epidermal walls and butterfly-shaped stomatal ledges, although some variation was seen in the ornamentation of the periclinal epidermal walls and the appearance of the stomatal complex. Based on these results, we recognized four groups and two subgroups among the South-east Asian species. Comparison with congeneric taxa in the other countries indicates that butterfly-shaped stomatal ledges are often shared among the species across the regions. However, no cuticular features occur exclusively in any of the species groups of Cryptocarya studied here, nor in the genus as a whole. We consider that cuticular features are useful in the recognition of infrageneric groups within Lauraceae, bearing in mind that they might have evolved in parallel in different genera.

An account of the genus Hexapora (Lauraceae) is presented. It comprises morphological descriptions of the genus and species, a provisional IUCN conservation assessment, ecological information and taxonomic notes. The morphology of the genus is compared to that of a number of possible close relatives, leading to the conclusion that it most likely belongs within the Beilschmiedia clade, and is likely closely related to Sinopora.
