摘要
报道了蔷薇科李亚科三个种的改隶新组合,将广义李属中的背毛樱Prunushypotrichodes改隶为杏属中的背毛杏Armeniacahypotrichides;疏花稠李Prunuslaxiflora改隶为疏花樱Cerasuslaxiflora。进一步研究的结果,同意前苏联学者G.V.EreminetV.S.Simagin的意见,将稠李属中的种斑叶稠李Padusmaacki改隶为樱属中的斑叶樱Cerasusmaacki。斑叶樱花序上有时具有小的叶、绿色或褐色小苞片,显示出樱花类花序小苞片的起源和进化趋势;
Two new combinations are made here in the family Rosaceae. Prunus hypotrichodes is transferred to Armeniaca, and Prunus laxiflora to Cerasus. Further evidence showed G. V. Eremin et V. S. Simagin' treatment, transfering Padus maackii to Cerasus, is reasonable. Small leaves and/or green or brown bracteoles on inflorescences of Cerasus maackii indicate the origin of bracteoles and the different stages of their evolution within the genus Cerasus Mill.Cerasus laxiflora is considered as the most primitive one in the species with brown bracteoles.
