A taxonomic revision of the African genus Desplatsia Bocq. (Malvaceae – Grewioideae)

A taxonomic revision of Desplatsia Bocq. (Malvaceae s. lat. Juss., subfamily Grewioideae Hochr., tribe Grewieae Endl.) based on about 800 herbarium specimens is presented. Desplatsia is a genus of trees and shrubs found in tropical West and Central Africa and is characterized by subulately divided stipules, the absence of an androgynophore, stamens that are fused to a tube at the base, and large and distinctive fruits that are dispersed by elephants. Four species are recognized (D. subericarpa Bocq., D. chrysochlamys (Mildbr. &amp; Burret) Mildbr. &amp; Burret, D. dewevrei (De Wild. &amp; T.Durand) Burret and D. mildbraedii Burret) and 12 species names are placed into synonymy, two of which have been put into synonymy for the first time: D. floribunda Burret syn. nov. and D. trillesiana (Pierre ex De Wild.) Pierre ex A.Chev. syn. nov. All four species are widely distributed and their conservation status is assessed as Least Concern (LC). A key to the species, full species descriptions, illustrations, a specimen citation list and distribution maps are provided.</jats:p

Antibiotic activity of Plectranthus ornatus Codd., a Traditional Medicinal Plant

ABSTRACT The dichloromethane extract of Plectranthus ornatus Codd., a tradicional medicinal plant, showed antibiotic activity with minimum inhibitory concentration (MIC) values of 0.4 mg.mL-1 and 100 percent of biofilm inhibition against Staphylococcus aureus strains isolated from animals with mastitis infections. Based on these antibacterial activities, in addition to ethnopharmacological reports from healing men and farmers in Brazil, an herbal soap was produced from this active extract and was tested both in vitro and in vivo. In vivo assays conducted on these herbal soaps led to results similar to those previously conducted with the active extract. These results indicated the great potential of this plant for use as an excipient by preparing herbal antibacterial soaps as an alternative veterinary medicine aimed at controlling bovine mastitis infections on small Brazilian farms
