Hibiscus Linnaeus. Subfamily: Malvoideae. Tribe: Hibisceae. Common name: Hibiscus, Rose-mallow.
A genus of about 200-300 species, trees, shrubs, and herbs, of tropical to warm temperate areas. Hanes et al. (2024) have outlined a direction for splitting of Hibiscus into monophyletic genera.
Key advice:The epicalyx (sometimes referred to as the involucel) is a whorl of bracts immediately subtending the calyx; there are useful characters of the epicalyx used sparingly in the key.
