Two New Species of Rhododendron (Ericaceae) from Guizhou, China
中国贵州杜鹃属两新种

Two new species, Rhododendron eriobotryoides Xiang Chen & Jia Y. Hang and R. jinboense Xiang Chen & X. Chen (Ericaceae), from Guizhou Province, China are descried 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.
