Xylosma is a genus of flowering plants in the family Salicaceae. It contains around 100 species of evergreen shrubs and trees commonly known as brushhollies, xylosmas, or, more ambiguously, "logwoods". The generic name is derived from the Greek words ξύλον (xylon), meaning "wood, tree", and ὀσμή (osmé), meaning "smell", referring to the fragrant wood of some of the species. The Takhtajan system places it in the family Flacourtiaceae, which is considered defunct by the Angiosperm Phylogeny Group.

The World Checklist of Selected Plant Families was an "international collaborative programme that provides the latest peer reviewed and published opinions on the accepted scientific names and synonyms of selected plant families." Maintained by the Royal Botanic Gardens, Kew, it was available online, allowing searches for the names of families, genera and species, as well as the ability to create checklists.
Rhytidocaulon is a plant genus in the family Apocynaceae, first described in 1962. It is native to northeastern Africa and the Arabian Peninsula
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". The initial focus was on tropical African Floras, particularly Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa.

Arboa antsingyae is a tree found in western Madagascar. While A. antsingyae is currently classified as critically endangered, it is currently unknown if A. antsingyae is extant as the last observation of the species was in 1952. Previously it was classified as Erblichia antsingyae and Piriqueta antsingyae, however, phylogenetic analysis suggested reclassification of the species in Arboa.
Arboa integrifolia is a shrub or tree with yellow flowers that grows in the dry tropics of Madagascar. A. integrifolia was previously classified as Erblichia integrifolia, Paropsia integrifolia, Piriqueta integrifolia, and Piriqueta mandrarensis, however, phylogenetic analysis supports its classification as Arboa.
Arboa madagascariensis is a woody plant with yellow flowers native to Madagascar.
