An illustration of the female flower of the sedge plant. Carex is a genus of plants in the family Cyperaceae, commonly known as sedges (although other, related species are also called sedges, those of genus Carex may be called "true" sedges). It is the most species-rich genus in the family. The study of Carex is known as caricology.

An illustration of a disk-floret of the senecio flower. Senecio is a genus of the daisy family (Asteraceae) that includes ragworts and groundsels. The flower heads are normally rayed, completely yellow, and the heads are borne in branched clusters. Though of late the genus has been reviewed and split up, it still contains a vast number of species (about 1,500) of extremely wide form including leaf succulents, stem and tuber succulents, annuals, perennials, aquatic forms, climbers, shrubs and small trees. Some species produce natural pesticides (especially alkaloids) to deter or even kill animals that would eat them.
