About
Strobilanthes callosa (Synonym: Carvia callosa (Nees) Bremek) is a shrub found mainly in the low lying hills of the Western Ghats, all along the west coast of India. Its standardized Hindi name is maruadona (मरुआदोना) which it is called in the state of Madhya Pradesh where it is also found. In the state of Maharashtra, in the Marathi language, and other local dialects and in the neighboring state of Karnataka, the shrub is locally known as karvi (कारवी), sometimes spelled in English as karvy.
This shrub belongs to the genus Strobilanthes which was first scientifically described by Nees in the 19th century. The genus has around 350 species, of which at least 46 are found in India.
