Plocama rosea (Hemsl. ex Aitch.) M.Backlund & Thulin | |
Aitchisonia rosea is a species of flowering plant in the family Rubiaceae. It is a subshrub native to south-central Iran, Afghanistan, and Pakistan. It is the sole species in genus Aitchisonia.[3]
The species and genus were named in 1882.[3] Based on a phylogenetic analysis, Backlund and Thulin synonymized Aitchisonia with genus Plocama, and renamed the species Plocama rosea.[4] In 2022 Borbar et al. concluded that the specimen used in Backlund and Thulin's analysis was of Plocama dubia, and conducted a phylogenetic analysis of specimens newly collected in Iran. They confirmed the placement of Aitchisonia rosea in its own genus, and proposed a new monophyletic tribe, Aitchisonieae, to contain the genus.[5]
