Homalanthus is a genus of plants in the family Euphorbiaceae, first described in 1824. [2] It is the only genus in the subtribe Carumbiinae. It is native to mainland Southeast Asia, Malesia, Papuasia, northern and eastern Australia, and various islands in the Pacific. [1] [3]
When published, the generic name was spelt as 'Omalanthus'. [2] Since the name comes from the ancient Greek word homalos meaning 'smooth' and anthos meaning 'flower', this original spelling was inconsistent with the general Greek transliteration rules, and many later authors changed it to Homalanthus. According to the International Code of Nomenclature for algae, fungi, and plants, Homalanthus has now been conserved against the original Omalanthus. [4]
As of July 2024 [update] , Plants of the World Online recognises 23 species in this genus, as follows: [1]
Antidesma is a genus of tropical plant in the family Phyllanthaceae formally described by Linnaeus in 1753. It is native to tropical Africa, S + E + SE Asia, Australia, and various oceanic islands. The greatest diversity occurs in Southeast Asia.
Claoxylon is a flowering plant genus in the spurge family, Euphorbiaceae, comprising dioecious subshrubs to small trees. It was first described as a genus in 1824. The genus is distributed in paleotropical areas: Madagascar through South and Southeast Asia, Malesia to Melanesia, Hawaiʻi, and Australia. Half of the species are in Malesia. According to a molecular phylogenetic study by Wurdack, Hoffmann & Chase (2005), Claoxylon is sister to Erythrococca, and together they form the top of a Hennigian comb-like phylogeny.
Melanolepis is a plant genus of the family Euphorbiaceae, first described as a genus in 1856. It is native to Southeast Asia, New Guinea, and some islands of the western Pacific.
Endospermum is a genus of plants, under the family Euphorbiaceae and the monotypic subtribe Endosperminae first described as a genus in 1861 They are dioecious, rarely monoecious trees. It is native to E + S + SE Asia, Papuasia, Queensland, and certain islands of the W Pacific.

Didymocheton is a genus of flowering plants in the family Meliaceae. It includes 41 species which range from eastern India through Indochina and southern China to Malesia, Papuasia, eastern Australia, New Zealand, and the South Pacific.
Sciaphila is a genus of mycoheterotrophic plants in the family Triuridaceae. These plants receive nutrition from fungi and neighboring trees and have less need for photosynthesis. It is widespread in tropical and subtropical regions, found in Africa, China, Japan, the Indian Subcontinent, Southeast Asia, Latin America and on various islands Pacific Islands. The most noteworthy feature of the genus is the number of the various flower parts 99.9 percent of Monocots are trimerous, but Sciaphila spp. can have eight or even ten parts in a whorl.
Rhomboda, commonly known as velvet jewel orchids, is a genus of about twenty species of flowering plants in the orchid family Orchidaceae. Plants in this genus are mostly terrestrial herbs with a fleshy, creeping rhizome and a loose rosette of green to maroon coloured leaves. Small resupinate or partly resupinate, dull coloured flowers are borne on a hairy flowering stem. The dorsal sepal and petals overlap and form a hood over the column and there is a deep pouch at the base of the labellum. They are found in tropical regions from northern India through Southeast Asia, China, Japan to Australia and some Pacific Islands.
Melanolepsis multiglandulosa is a species of plant in the family Euphorbiaceae, first described in 1826. It is native to Nansei-shoto, Mariana Islands, Solomon Islands, Bismarck Archipelago, New Guinea, Maluku, Sulawesi, Philippines, Lesser Sunda Islands, Java, Sumatra, Borneo, Thailand, Malaysia and Taiwan.
