摘　　要：为了更好地认识云南红花油茶的多样性,解决其种内分类不一致的问题,采用直接观察计数、数理统计和数量分类学的方法对云南省楚雄市、腾冲市和盘龙区挂牌的60株云南红花油茶进行了关键分类性状花瓣数量的观察和分析。结果表明,云南红花油茶花瓣5-68片,基于花瓣数量聚类分析可划分为2类4亚类。经充分讨论花瓣数量演化、种内分类系统和分类等级后,修订了已有的云南红花油茶种内分类系统,重新构建了更合理和实用的新种内分类系统,将云南红花油茶分为4个变种。最后,报道了重瓣红花油茶和叠瓣红花油茶2个新变种和腾冲红花油茶1个新等级,为云南红花油茶多样性的认识及其油用或观花优良新品种的选育等实际工作提供参考。In order to better understand the diversity and to solve the inconsistent problems on intraspecific classification of Camellia reticulata Lindley,the petal numbers,a key taxonomical character,of 60 labeled individuals of this species from Chuxiong Municipality,Tengchong Municipality and Panlong District,Yunnan were observed and analyzed with the methods of directly counting,mathematical statistics and numerical taxonomy.The results show that the petal numbers of the species are from 5 to 68.The species can be divided into 2 groups and 4 subgroups based on the cluster analysis of its petal numbers.After full discussion on the evolution of its petal numbers,the system and the rank of its intraspecific classification,the currently-known system of intraspecific classification of Camellia reticulata Lindley was revised and a new system of its intraspecific classification,which are more reasonable and practical,was reconstructed.In this new system,a total of 4 varieties were to be recognized,of which two,Camellia reticulata var.pleiopetala Sima and Camellia reticulata var.pleistopetala Sima,were described as new variety and one,Camellia reticulata var.simplex(Sealy)Sima,was made as new rank.It will present a necessary scientific guidance for the diversity understanding and the breeding selection of excellent or new cultivars for oils or ornamental flowers of Camellia reticulata Lindley.
