| 对于中国马尾藻属，真马尾藻亚属滑托组Malacocarpicae（J. Ag．）Abbott，Tseng et Lu．总状托序亚组suhection Racemosae,具腺系Series Glandulariae的种类进行了系统的研究。结果表明，中国共有具腺系3个种，除棒托马尾藻前人已经报道外，本文建立了两个新种，它们是：1．线形马尾藻，模式标本于1955年5月7日来自广东省硇洲岛，模式标本号为AST55－2259；2．钦州马尾藻，模式标本于1955年5月7日采自广西钦州湾龙门镇，模式标本号为AST55－1987。两者的模式标本均保存于中国科学院海洋研究所藻类标本室。 |

| Abstract: |
| In the present study a taxonomic study was made of two new species of Chinese Sargassum belonging to the Series Glandulariae of the subsection Racemosae, namely Sargassum capilliforme sp. nov. and Sargassum qinzhouense sp. nov.
Sargatsum capilliforme sp. nov. is a very slender species, characterized by its filiform leaves, entire at the margins, without midrib, its glandular branchlets, and smooth, and shortly racemosely arranged male and female receptacles. The present species is apparently closely related to Sargatsum filifalium C. Ag. (Grunow, 1915) and Sargassum filiforme Montagne (Grunow, 1916), both belonging to Parvifoliae J. Agardh of Section Acanthocarpicae.
Sargassum qinzhouense sp. nov. is characterized by its prominently elevated glandular branchlets and its racemosely branched, cylindrical, smooth male receptacles, the central receptacles of the branchlet retaining apical growth, continuing to give rise to new receptacles. It is closely related to S. siliquosum, differing in its smaller, less oblique basal part of the leaf and continued apical growth of the central receptacls. |
