| As espécies do gênero Manihot apresentam algumas características comuns que permitem sua identificação, como o porte e conformação das plantas, flores masculinas e femininas separadas (Figura 2) e frutos bacáceos com estrias laterais. Manihot caerulescens apresenta grande plasticidade fenotípica. Podem ser encontradas como arbustos eretos ou árvores de até 10 metros de altura, altamente ramificados, apresentam plantas monoicas com presença de látex amarelado (o que a distingue das demais espécies); ramos não viscosos, ferrugíneos, puberulentos, tricomas tectores. Folhas alternas, limbos papiráceos, com 5 a 7 lóbulos, semelhantes entre si, 8-15x4-6cm obovados, as vezes panduriforme, venação broquidódroma, nervuras amareladas a castanhas, ápice acuminados ou... |

| The leaf anatomical diversity of the genera Baccaurea Lour. (43 species), Distichirhops Haegens (3 species) and Nothobaccaurea Haegens (2 species) (Euphorbiaceae) is described. Two species of Aporosa and three species of Maesobotrya were examined for comparison. The following characters are important for the delimitation of species: hair types, the position of the glandular areas on the leaf margin, the hairiness and size of the glandular areas, the number of epidermal layers, the presence of (mucilage) idioblasts in the epidermis, the presence of palisade parenchyma above the vascular bundles, and the birefringence of the spongy parenchyma cell walls. However, leaf anatomy did not yield characters for distinction between the five genera studied. Phenetic... |

| Dimorphocalyx, a small genus ranging from Sri Lanka to Indomalesia to Australia, has eight species in Malesia, of which one is here raised from variety to species level and another, endemic in the N Moluccas, is newly described. Dimorphocalyx murinus and – tentatively – D. loheri are synonymised with D. denticulatus, and D. luzoniensis is synonymised with D. malayanus. Dimorphocalyx cumingii is regarded as a species of Trigonostemon. The differences between Dimorphocalyx, Ostodes, Paracroton (formerly Fahrenheitia), and Trigonostemon are discussed. |

| Mallotus concinnus Airy Shaw, M. havilandii Airy Shaw, M. insularum (Airy Shaw) Slik, and M. miquelianus (Scheff.) Boerl. are very similar in appearance, with opposite leaves of which one large and elliptic, and the other reduced and more or less obcordate. However, a detailed look revealed enough differences to regard them as distinct species. |

| Micrococca is a rare genus represented in the Malesian region by only three species. Micrococca mercurialis (L.) Benth. is widespread, but in Malesia it is found only in Peninsular Malaysia. Micrococca malaccensis Airy Shaw and M. johorica Airy Shaw are both endemic to Johore. Micrococca can be distinguished from its close allies, Erythrococca and Claoxylon, by its interrupted racemes (with long internodes), pistillate flowers with elongated (strap-like) disc lobes, and a deeply 3-lobed, thinly crustaceous capsule dehiscing both septicidally and loculicidally. Micrococca mercurialis is a small-leaved shrub, while the other two species are trees with much larger leaves. Micrococca johorica has glands on the leaf bases, narrow leaves, and short... |

| Based on phylogenetic studies with DNA sequence data, the formerly monotypic genus Cordemoya was recently expanded with 16 additional species previously assigned to Mallotus. However, the earliest legitimate generic name available is Hancea, and, therefore, Cordemoya is here reduced to Hancea (20 new combinations are proposed). Subsequently, the subgenus and section Diplochlamys from Asia are renamed to Hancea. Additionally, the genus Adisca is lectotypified with Adisca floribundus (= Mallotus floribundus). |

| Malesia harbours one, possibly two species of Blachia. In the Philippines B. philippinensis is found and this species is not synonymous with B. andamanica. In literature B. andamanica has been recorded for west Malesia, but no specimens were seen. Based on its presence in Peninsular Thailand and the Andamans it is likely to be present in Peninsular Malaysia. The most distinct difference between both species is in the indumentum of the ovary, sparsely hairy in the lower half versus densely and completely sericeous, respectively. |

| Jatropha, a widespread, species rich genus, ranges from the Americas and Caribbean to Africa and India. In Malesia five species occur, all of which were introduced and originated in Central and South America. The five species are revised and an identification key, nomenclature, descriptions, distributions, ecology, vernacular names, uses and notes are provided. Special attention is given to the uses of J. curcas, because it is steadily gaining popularity as a potential biofuel plant and, because of that, is being cultivated more often. |
