First report of Torenia concolor (Linderniaceae) from India and notes on typification of associated names

Torenia concolor is a Southeast Asian species, originally described from Hong Kong, and is known to be distributed in China (incl. Taiwan), Laos, Myanmar, and Vietnam. As a result of material revision at different herbaria, collections of T. concolor from Indian borders were found at CAL and GUBH, and therefore this species is reported from India for the first time. Lectotype of T. concolor is also designated here, along with typification of some associated names. Torenia rubens is synonymized as a junior synonym of T. diffusa.
