Chrysogonum Repens
''Chrysogonum'' is a genus of flowering plants in the family Asteraceae. , two circumscriptions of the genus were in use. In the broader circumscription, the genus has a discontinuous distribution, with species native to eastern North America and Madagascar. In the narrower circumscription, the genus contains only species native to eastern North America. Description The plants are low-growing terrestrial herbs with yellow flower heads containing both disc and ray florets. The genus is distinctive in having pistillate ray florets and staminate disk florets, and the pistil of the ray floret is fused to the adjacent phyllary as well as three paleae and their associated disk florets to form a "cypsela complex". Taxonomy The genus ''Chrysogonum'' was erected by Carl Linnaeus in 1753 for the North American species ''Chrysogonum virginianum''. Seven species were accepted by Plants of the World Online : two further North American species, and four Madagascan species added by Jean-Henri ...

Aspilia
''Aspilia'' is a genus of flowering plants in the family Asteraceae. ''Aspilia'' is native to sub-Saharan Africa, Madagascar, Yemen, and tropical South America. Some authors have merged this genus with '' Wedelia'', but others maintain that more study is required. Medicinal uses Historically, '' Aspilia africana'' was used in Mbaise and most Igbo speaking parts of Nigeria to prevent conception, suggesting potential contraceptive and anti-fertility properties. Leaf extract and fractions of ''A. africana'' effectively arrested bleeding from fresh wounds, inhibited microbial growth of known wound contaminants and accelerated wound healing process. ''Aspilia'' is hypothesized to be used as herbal medicine by some chimpanzees The chimpanzee (; ''Pan troglodytes''), also simply known as the chimp, is a species of great ape native to the forests and savannahs of tropical Africa.

Jean-Henri Humbert
Jean-Henri Humbert (24 January 1887 – 20 October 1967) was a French botanist born in Paris. He studied physics, chemistry and natural sciences in Rennes and Paris, and following a scientific excursion to Madagascar, he worked as a university assistant at the faculty of Clermont-Ferrand (from 1913). In 1919 he was appointed to the chair of botany, subsequently teaching botany classes at the institute of chemistry and industrial technology (1920–22). In 1922 he relocated to Algiers, where he became ''chef de travaux'' to the faculty of sciences. In 1931 he succeeded Henri Lecomte (1856-1934) as chair of botany at the Muséum national d'histoire naturelle in Paris.

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...
