摘　　要：为了解中国南海北部凹顶藻物种的多样性以及加快该地的凹顶藻属物种资源开发和利用,本研究利用形态学和解剖学方法,对采自广东汕尾的大型海洋红藻凹顶藻类(Laurencia Complex)进行分类学研究。经鉴定共发现4个物种,即波状软凹藻(Chondrophycus undulatus(Yamada)Garbary et Harper)、凹顶藻(Laurencia chinensis Tseng)、三列凹顶藻(L.tristicha Tseng,Chang,Xia et Xia)和小瘤栅凹藻(Palisada parvipapillata(Tseng)Nam)。文中对此4种凹顶藻类物种的内、外部形态特征进行了较详细的描述与介绍,并结合生物冷冻切片技术,获得了各个物种较清晰的解剖学特征图片,对未来凹顶藻类物种的鉴定提供一定分类学意义。In order to understand the diversity of Laurencia Complex species in the northern part of the South China Sea and to accelerate the development and utilization of Laurencia Complex resources in this area.Based on the morphological and anatomical methods,taxonomic research on the large marine red algae Laurencia Complex collected from Shanwei,Guangdong was conducted.After identification,a total of 4 species were found,namely Chondrophycus undulatus(Yamada)Garbary et Harper,L.chinensis Tseng,L.tristicha Tseng,Chang,Xia et Xia and Palisadaparvipapillata(Tseng)Nam.The internal and external morphological characteristics of these four species of Laurencia Complex were described and introduced in more details in this article.Combined with biological frozen section technology,clearer pictures of anatomical features of various species were obtained.It is hoped that it will provide a certain taxonomic significance for the identification of L.Complex in the future.
