| 近几年来,我们对中国科学院海洋研究所1957-1980年先后5次在西沙群岛近20个岛屿、沙洲和礁滩进行调査所采获的珊瑚藻标本做了全面的检査和比较研究工作。西沙群岛的珊瑚藻种类比较丰富,除已报道的14种4个变型外,本文又报道了6种3个変型,即薄売藻 Leptophytum asperulum (Fosl.)Adey,布氏水石藻 Hydrolithon boergesenii (Fosl,)Fosl，太平洋小石孔藻 Lithoporella pacifica ( Heydr.)Fosl,巨囊新角石藻 Neogoniolithon megalocystum (Fosl.) Setchell et Mason,孔石藻亚突变型 Porolithon onkodes ( Heydrich) Fosl.f. subramosa Fosl.和孔石藻帽状变型 P. onkodes f. devia Fosl.,冈村石叶藻 Lithophyllum okamurai Fosl.,脆叉节藻轮枝変型 Amphiroa fragilissima (Linn.)Lamx,f.cyathifera (Lamx.) Weber van Bosse,毛叉珊藻 Jania capillacea Harvey,均为我国新记录,此外,本文补充报道了太平洋新角石藻 Neogoniolithon pacificum (Fosl.) Setchell et Mason 的四分孢子体。 |

| Abstract: |
| The Institute of Oceanology, Academia Sinica, during 1956, 1957, 1975, 1976, 1980，carried out five scientific surveys on about twenty isles of the Xisha Islands. Morphological and systematic studies were made on the basis of the materials collected from the above surveys. With the exception of 14 species and 4 forms, already reported from the Xisha Islands, [1,2,3] the other 6 species and 3 forms, namely, Leptophytum asperulum (Fosl ) Adey, Hydrolithon boergesenii (Fosl) Fosl, Lithoporella pacifica (Heydr ) Fosl, Neogoniolithon megalocystum ( Fosl ) Setchell et Mason, Porolithon onkodes (Heydr.) Fosl. f. subramosa Fosl and f devia Fosl, Lithophyllum okamurai Fosl, Amphiroa fragilissima (Linn) Lamx.f. cyathifera (Lamx )Weber van Bosse, Jania capillacea Harvey, are recorded to be new to China.In this paper,the record of tetrasporophyte in Neogoniolithon pacificum (Fosl )Setchell et Mason is supplemented for the Chinese marine flora.
Most of the species are of tropical and subtropical algae and found in the Indian Ocean and the Pacific Ocean. Among them, Porolithon nokodes, Neogoniolithon variabile and Neogoniolithon frutescens are particularly abundant, Hydrolithon reinboldii and Neogoniolithon trichotomum can also be found readily. Up to the present, 20 species and 7 forms of Corallinaceae have been reported, but the total number of species on the Xisha Islands may be over 40. It is because that the specimens of some species used for study were rare, others with reproductive organs, especially the asexual reproductive organs were lacking or scarce,in addition, epiphytic and deep water species needed further study. The above facts have shown that the Xisha Islands have a rich corallinaceous algal flora. |
