【摘要】 报道了中国贵州杜鹃属植物2新种——枇杷叶杜鹃(Rhododendron eriobotryoides Xiang Chen&Jia Y.Huang)和金波杜鹃(R.jinboense Xiang Chen&X.Chen)。枇杷叶杜鹃与皱叶杜鹃(R.denudatum)相似,但本种叶背毛被较薄而稀疏,花丝基部密被微柔毛,花柱通体被腺体。金波杜鹃与短脉杜鹃(R.brevinerve)相似,但前者的叶长圆状椭圆形,叶片上卷呈U形,花序具较多花,花冠较长,花丝基部密被微柔毛,子房密被绒毛。目前,仅发现2新种各有1个含数株的种群,资源量十分稀少,依据IUCN红色名录标准均属于极危物种(CR),需要加以重点保护。更多还原

【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.更多还原
