John Charles Manning (1962-) was born in Pietermaritzburg, South Africa. He is a botanist based in the Compton Herbarium, South African National Biodiversity Institute (SANBI), researching on the systematics in South African flora. He specializes on Colchicaceae, Iridaceae, Haemodoraceae and Hyacinthaceae.

In 2014, Manning et al. published “A Molecular Phylogeny and Generic Classification of Asphodelaceae Subfamily Alooideae: A Final Resolution of the Prickly Issue of Polyphyly in the Alooids?” in Systematic Botany. Based on molecular phylogenetic studies, they produced a phylogeny of the tribe Aloeae of the family Asphodelaceae, and divided the genus Haworthia into 3 genera: Haworthia is restricted to H. subg. Haworthia; the genus Tulista is accepted for members of H. subg. Robustipedunculatae, with the new combination T. minima; and H. subg. Hexangulares is treated as the genus Haworthiopsis with the new combinations H. koelmaniorum, H. pungens, and H. tessellata.
