Justicia (plant)
Template:Short description Template:Automatic taxobox
Justicia is a genus of flowering plants in the family Acanthaceae. It is the largest genus within the family, with over 900 accepted species.[1] They are native to tropical to warm temperate regions of the Americas, India, and Africa. The genus serves as host to many butterfly species, such as Anartia fatima. Common names include water-willow and shrimp plant, the latter from the inflorescences, which resemble a shrimp in some species. The generic name honours Scottish horticulturist James Justice (1698–1763).[2] They are closely related to Pachystachys.[3]
