Carduus subgenus Afrocarduus Kazmi (1963) | |
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.[2]
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.[2]
