It is morphologically similar to I. liangshanense, but is readily distinguished by leaf blade which are often trullate-lanceolate, and sometimes ovate-lanceolate or lanceolate, base auriculate, abaxially densely hook-haired and pedicel ca. 3 cm long, gynostemium 3-lobed, apex obtuse, nondivergent and not curved inward. In addition to a diagnosis and detailed description, information on the morphological characters and a provisional conservation status assessment are also provided for this species.
