Rediscovery of Typhonium inopinatum (Araceae) from India with notes on the identity of T. khandwaense

Abstract

Typhonium inopinatum Prain is rediscovered after a lapse of 115 years from Gautam Buddha Wildlife Sanctuary in Bihar. As the species is very rare and without sufficient details in any of the Indian floras, a detailed taxonomic description, photoplates and note on distribution are provided to facilitate easy identification. A lectotype is also designated here. The identity of recently described T. khandwaense is deliberated and is reduced to the synonym of T. inopinatum.
