Arachnothryx is a genus of flowering plants in the family Rubiaceae. It contains about 107 species. It is found from Mexico to Peru and in Trinidad. [1]
Arachnothryx was named by Jules Émile Planchon in 1849. [2] [3] This generic name is derived from Ancient Greek: arachne or arachnos, "a spider", and thrix or trichos, "hair". [4]
As currently circumscribed, Arachnothryx is paraphyletic over Cuatrecasasiodendron, Gonzalagunia , and Javorkaea. Some authors have included these genera in a broadly defined Rondeletia , but molecular phylogenetic studies have shown that they are more closely related to Guettarda than to Rondeletia . [5]
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," 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.
Sideroxylon is a genus of trees in the family Sapotaceae described as a genus by Linnaeus in 1753. They are collectively known as bully trees. The generic name is derived from the Greek words σιδηρος (sideros), meaning "iron", and ξύλον (xylon), meaning "wood."
