Justicia gambleana (Acanthaceae): a new species from Kerala, India

A taxonomic revision of the genus Justicia (Acanthaceae) in Peninsular India

“…The genus is represented by 51 species and five varieties in India (Karthikeyan et al, 2009) with a high level of endemism in Peninsular India. Due to a diverse inflorescence structure and floral morphology (including size, shape and colour of the flowers), the genus presents a challenge in infrageneric circumscription, leading to the discovery of many species and varieties from India (Clarke, 1885;Ellis, 1969;Graham, 1988;Remadevi & Binojkumar, 2008;Annamma et al, 2016;Prabhukumar et al, 2016).…”
