Afrocarduus
''Afrocarduus'' is a genus of flowering plants in the sunflower family, Asteraceae. It includes ten species of thistles native to the mountains of tropical Africa, ranging from Nigeria to Ethiopia and Zimbabwe. All the species in the genus are native to Afromontane or Afroalpine regions of Africa, ranging from 1600 and 4600 meters elevation. Some are restricted to a single mountain or mountain range, while others are native to two or more ranges, some widespread. The species now placed in genus ''Afrocarduus'' were previously placed in genus ''Carduus'' as subgenus ''Afrocarduus''. The sub-Saharan African species have morphological and karyological features of genera ''Carduus'' and ''Cirsium''. A phylogenetic study by Moreyra ''et al.'' concluded that these African species formed a clade distinct from ''Carduus'' and ''Cirsium'', and sister to the newly described genus ''Afrocirsium''.

Carduus
''Carduus'' is a genus of flowering plants in the family Asteraceae, and the tribe Cardueae, one of two genera considered to be true thistles, the other being ''Cirsium''.

Afrocirsium
''Afrocirsium'' is a genus of flowering plants in the sunflower family, Asteraceae. It includes three species of thistles native to the mountains of eastern tropical Africa. They are spiny perennial herbs growing 0.5 to 2.5 meters tall. They have the plumose pappus characteristic of genus ''Cirsium'', but have distinct characteristics like phyllaries with well-developed pectinate appendages which are not present in ''Cirsium'' and the other genera in the ''Carduus-Cirsium'' group.Moreyra, Lucía D., Núria Garcia-Jacas, Cristina Roquet, Jennifer R.

Afroalpine
The Afromontane regions are subregions of the Afrotropical realm, one of the Earth's eight biogeographic realms, covering the plant and animal species found in the mountains of Africa and the southern Arabian Peninsula. The Afromontane regions of Africa are discontinuous, separated from each other by lower-lying areas, and are sometimes referred to as the Afromontane archipelago, as their distribution is analogous to a series of sky islands. Geography Afromontane communities occur above elevation near the equator, and as low as elevation in the Knysna-Amatole montane forests of South Africa. Afromontane forests are generally cooler and more humid than the surrounding lowlands. The Afromontane archipelago mostly follows the East African Rift from the Red Sea to Zimbabwe, with the largest areas in the Ethiopian Highlands, the Albertine Rift Mountains of Uganda, Rwanda, Burundi, Democratic Republic of the Congo, and Tanzania, and the Eastern Arc highlands of Kenya and Tanzania ...
