Abstract:Two new species, Rhododendron eriobotryoides Xiang Chen & Jia Y. Huang and R. jinboense Xiang Chen & X. Chen (Ericaceae), from Guizhou Province, China are described and illustrated. Rhododendron eriobotryoides is close to R. denudatum from which it differs by having thinner and sparser flocculence on the leaf blade abaxial surface, puberulent filaments, and a glandular style. Rhododendron jinboense differs from the most morphologically similar species R. brevinerve by the former’s oblong-elliptic and U-shaped leaf blades, a more floriferous inflorescence, a longer corolla, puberulent filaments, and a densely tomentose ovary. Both of the new species are Critically endangered, (CR), based on the IUCN Red List Categories and Criteria, therefore, careful protection is highly desired.
