Lysionotus bijantiae is identified as a new synonym of Henckelia oblongifolia (Gesneriaceae)

A recently described new species of Gesneriaceae, Lysionotus bijantiae D. Borah & A. Joe, was misidentified; it is conspecific with Henckelia oblongifolia (Roxb.) D. J. Middleton & Mich. Möller [previous Chirita oblongifolia (Roxb.) Sinclair]. We treat Lysionotus bijantiae as a new synonym for Henckelia oblongifolia by examining relevant specimens and literature. At the same time, we also describe the characteristics and distinguishing methods of the two genera Henckelia Spreng. and Lysionotus D. Don.
