The winter bud scales are tough and membranous. The leaf blade is about 3.5-6.5 cm in length and width. The flowering period is from June to July.

One of the meshes where the population size was unknown is currently uncertain, while the other two meshes have a slightly rare occurrence. In another mesh, only a few individuals are observed. Although it was listed as "Data Deficient" in the IUCN Red List, the population is probably less than 250 individuals, which corresponds to "Endangered"[EN].
