| 根据Feldmann(1938)的评述，管枝藻目的系统分类研究工作始于Schmitz(1879)，他首先创建了“group” Siphonocladaceae(发表名为Siphonocladiaceae)。又据Egerod(1952)的研究，Schmitz的“group”事实上只是一个科，Feldmann(1938)，Fritsch(1947)及其他人把管枝藻目的创建者归诸Schmitz是错误的。Schmitz在此科中收容了法囊藻(Valonia)，肋叶藻(Anadyomene)，小网藻(Microdictyon)，刚毛藻(Cladophora)，硬毛藻(Chaetomorpha)，黑孢藻(Pithophora)，气球藻(Botrydium)和暂定的网叶藻(Struvea)以及他的新属管枝藻(Siphonocladus)。De Toni(1889)将Schmitz的管枝藻科的各属分散在Order Confervoideae的刚毛藻科的刚毛藻亚科(Cladophoreae)、绵枝藻亚科(Spongocladieae)、小网藻亚科(Microdictyeae)、肋叶藻亚科(Anadyomene)和法囊藻亚科(Valonieae)中。Blackman and Tansley(1902)简历管藻目时下分管藻亚目(Siphoneae)包括无分隔的种类和管枝藻亚目(Siphonocladeae)包括分隔的种类；后者由孢根藻科(Gomontiaceae)，刚毛藻科(Cladophoraceae)，环藻科(Sphaeropleaceae)和法囊藻科(Valoniaceae)等四个科组成。 |

| Abstract: |
| The present report is based upon two collections of seaweeds by the members of the Institute of Oceanology in 1957 and 1958 from the Xisha Islands--a group of South China Sea coral islands located about 170 miles southeast from Yulingkang of the Hainan Island, between 15°46'and 17°8'N, and 110°11' and 112°54' E.
The algal flora of these coral islands is very imperfectly known. In their report on the Chinese species of Dictyosphaeria by Tseng and C. F. Chang (1962), four species including one new species D. spinifera were from Xisha Islands. In his study of the distribution of Chinese Siphonocladales, Fan (1963) listed 14 species including these four species.
In the present paper twenty species belonging to ten genera and four families are reported, of which six species including two new species are recorded for the first time from Xisha Islands. |
