Abstract
Hemiboea liana, a species of Gesneriaceae new to science found in northern Guangxi, China, is described and illustrated. While sharing morphological similarities with H. chanii and H. sinovietnamica, the new species can be distinguished by a distinct combination of traits, such as its brown rounded squared hard stem and trigonous purple-light brown involucre. Detailed information is provided, including a morphological description, illustrations, diagnostic comparisons, and a molecular phylogenetic analysis placing the new species among 30 out of 44 species currently recognized in Hemiboea.

Diagnosis: Morphologically, H. liana and H. chanii are most similar, but they can be distinguished by the shape and length of the stem (shape: rounded square vs. subterete; length: 10–46 cm vs. 50–90 cm), leaf blade size (4.7–8.3 × 2.8–3.8 cm), shape and color of the involucre (shape: trigonous vs. diamond; color: purple-light brown vs. light green), corolla color (pink-spotted vs. pink), and the shape of the filament and anther (filament: narrowly linear vs. filiform; anther: semicircular vs. basifixed). In addition, this new species has the same involucre shape as H. sinovietnamica, but their involucres are different in color (purple-light brown vs. green). In addition, they can be distinguished by their ...
Etymology: The name of this newly discovered species, Hemiboea liana, is in honor of LI Zhen-Yu, for his significant contributions to the study of Gesneriaceae, including Hemiboea.
