Abstract: A recently described new species of Gesneriaceaeꎬ Lysionotus bijantiae D. Borah & A. Joeꎬ was misidentifiedꎻ
it is conspecific with Henckelia oblongifolia (Roxb.) D. J. Middleton & Mich. Möller. We treat Lysionotus bijantiae as a
new synonym for Henckelia oblongifolia [ previous Chirita oblongifolia ( Roxb.) Sinclair] by examining relevant
specimens and literature. The type specimens of Lysionotus bijantiae were collected from the southern slope of the
Himalayas in Southeast Xizangꎬ China. The diversity of Gesneriaceae in this area is also abundant. The authors attributed
it to the genus Lysionotus because of its flower with two stamensꎬ and compared it with other Lysionotus species because
of its calyx 5 ̄lobed above the middleꎬ but they ignored the fact that the seed apex had no appendages. We observed that
the seeds of this species in the populations of Motuo and the type localities both had no appendages by scanning the seeds
with electron microscopeꎬ it is confirmed that this species is not a species of Lysionotusꎬ but a species of Henckelia. At
the same timeꎬ we offer the color images (including seeds scanned images) and the lectotype of Henckelia oblongifoliaꎬ
and also describe the characteristics and distinguishing methods of the two genera Henckelia Spreng. and Lysionotus
D. Donꎬ in order to provide a reference for species identification of the two genera and avoid more confusion of species
classification.
