Virectaria
''Virectaria'' is a genus of flowering plants in the Family (biology), family Rubiaceae. The genus, known as ''Virecta'' until 1952, consists exclusively of tropical African species. It is a Guineo-Congolian genus, having its highest diversity in Lower Guinea but it also occurs in the Zambezian Region. Bernard Verdcourt, Verdcourt provided a revision in which he defined five species but three more were added later. In 2001, a detailed morphological and anatomical study of the genus was conducted and a taxonomic survey and a key to the species was provided. Description All species are herbaceous or semi-woody and possess a fruit dehiscence type that is unique for the family; the splitting into one persistent and one deciduous valve allows recognizing the genus at first glance. In habit, ''Virectaria'' strongly resembles African Hedyotideae such as ''Otomeria'' and ''Parapentas'' but it lacks some diagnostic features of that tribe, viz. raphides, articulate hairs, heterostylous flow ...

Medicinal Plants
Medicinal plants, also called medicinal herbs, have been discovered and used in traditional medicine practices since prehistoric times. Plants synthesize hundreds of chemical compounds for various functions, including Plant defense against herbivory, defense and protection against insects, fungi, Plant disease resistance, diseases, against parasites and herbivorous mammals. The earliest historical records of herbs are found from the Sumerian civilization, where hundreds of medicinal plants including opium are listed on clay tablets, . The Ebers Papyrus from ancient Egypt, , describes over 850 plant medicines. The Greek physician Pedanius Dioscorides, Dioscorides, who worked in the Roman army, documented over 1000 recipes for medicines using over 600 medicinal plants in , ; this formed the basis of pharmacopoeias for some 1500 years. Drug research sometimes makes use of ethnobotany to search for pharmacologically active substances, and this approach has yielded hundreds of use ...
