Abstract: In this paper , some systematical problems, including the classification , differentiation , and systematic relationships between genera of Tamaricaceae, are discussed . Tamaricaceae , together with the family Frankenaceae as sister group , is positioned in the Caryophyllales or Caryophyllidae of the Angiospermae. Based on morphological and molecular evidences , we give support to include Hololachna within the genus Reaumuria , and the establishment of the genus Myrtama Ovcz . & Kinz . Tamaricaceae is composed of two tribes: Trib . Reaumurieae Niedenzu and Trib . Tamariceae Niedenzu ( including Tamarix ,Myrtama and Myricaria) , with the genus Tamarix as evolutionary intermediate .

Key words: Tamaricaceae

摘要： 综合多方面研究结果, 对柽柳科系统学研究中的一些问题, 包括科的系统位置、属的划分及分化进行了探讨, 认为: 柽柳科和瓣鳞花科(Frankenaceae) 构成姊妹类群, 同属于石竹目或石竹亚纲; 基于形态和分子证据, 认为红砂属归入琵琶柴属、山柽柳属独立成属更为合理, 但山柽柳属是否为杂交属尚需进一步研究。柽柳科包括红砂族( 仅包括琵琶柴属) 和柽柳族(包括柽柳属、山柽柳属、水柏枝属) , 柽柳属联结红砂族和柽柳族。
