在2011~2013年间对粤东地区进行了20余次野外大型海藻资源调查, 采集了大量标本。利用形态特征, 对部分标本进行了分类学研究。经鉴定, 标本中包含江蓠属5个种及变种, 即芋根江蓠Gracilaria blodgettii Harvey、异枝江蓠G. bailinae Chang et Xia、细基江蓠G. tenuistipitata Chang et Xia、细基江蓠繁枝变种G. tenuistipitata var. liui Zhang et Xia、长喙江蓠G. longirostris Zhang et Wang。它们的主要鉴定特征分别为: 芋根江蓠的分枝基部明显缢缩; 异枝江蓠的藻体暗绿色, 初级分枝围绕主轴互生、偏生或叉分; 细基江蓠的藻体主轴基部纤细, 分枝简单; 细基江蓠繁枝变种的藻体纤细, 分枝繁多; 长喙江蓠的囊果具有明显的长喙状突起。其中, 芋根江蓠和异枝江蓠在粤东地区属首次报道, 文章对其进行了较详细的介绍。该研究结果丰富了粤东江蓠属的物种多样性, 为粤东地区江蓠属物种资源的保护和利用提供了分类学依据。

The authors surveyed the macroalgal natural resources more than 20 times during 2011~2013, and collected a number of specimens. Based on the morphological characteristics, a taxonomical study on specimens was carried out. Among the identified specimens, there were five species of genus Gracilaria including a variant, G. blodgettii Harvey, G. bailinae Chang et Xia, G. tenuistipitata Chang et Xia, G. tenuistipitata var. liui Zhang et Xia and G. longirostris Zhang and Wang. Their main features include the branches and branchlets abruptly constricted at the base for G. blodgettii, dark green plants with alternate or dichotomous first-order branches for G. bailinae, slender base and simple branches for G. tenuistipitata, slender thalli and abundant branches for G. tenuistipitata var. liui, and cystocarp with distinctly long rostrate protuberance for G. longirostris. G. blodgettii and G. bailinae are two new records in the east coast of Guangdong province in China. The results enrich the diversity of Gracilaria species and provide the essential data for the protection and utilization of the resources of Gracilaria species in eastern Guangdong.
