- 摘要：Our recent investigations have shown that the Xisha Islands (Guangdong Province, China ) have a rich cyanophyceous flora. The present paper deals with descriptions of 10 species of marine blue-green algae belonging to 3 families and 6 genus of Chroococcales. With the exception of Chroococcus turgidus (Kuetzing) Naegeli and Entophysalis granulosa Kuetzing, respectively reported from Fujian and Shandong Provinces, the other 8 species, namely, Microcystis aeruginosa Kuetzing, Chrococcus minor (Kuetzing) Naegeli, C. limnticus Lemm. var subsalsus Lemm. C. varius A. Braun, C. membraninus (Meneghini) Naegeli, Gomphosphaeria aponina Kuetzing, Hormathonema epilithicum Ercegovic and Joannesbaptistia pellucida (Dickie)W. R. Taylor et Drouet ate recorded for the Chinese marine flora for the first time. During the last century, according to most of the current systems of classification of the Cyanophyta, the chroococcaleous algae were generally divided into 2 families, namely, Chroococcaceae and Entophysalidaceae. Until 1963, G. Claus proposed to retain the Tubiellaceae in the Chroococcales as one of its families. We agree with G. Claus’s point of view, to divide the Chroococcales into 3 families: Chroococcaceae, Entophysalidaceae and Tubiellaceae. The specimens of Johamnesbaptistia were collected from Zhongjian Island of the Xish Islands,in February 1976. The present specimens are closely resemblance to those specimens described by Drouet (1936 ) in shape and size. All of specimens studied are deposited in the Herbarium of Institute of Oceanology, Academia Sinica at Qingdao.关键词：MARINE BLUE-GREEN ALGAE;XISHA ISLAND

发布时间：2023-04-28 - 摘要：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.关键词：CORALLINACEA;XISHA ISLAND

发布时间：2023-04-28 - 摘要：Marine algae from the Xisha Islands, Guangdong Province, China collected by the members of the Institute of Oceanology(1957, 1958, 1975 and 1976)have been studied and some results published in a series of papers commencing in 1975. During the course of the study eleven species belonging to six sections and two subgenus are found, of which five species, namely Laurencia decumbens Kuetz. L. galtsoffi Howe, L. mariannensis Yam L. pinnata Yam, and L. cartilaginea Yam. are newly recorded here for China. Laurencia articulata Tseng from Hong Kong is founded on sterile specimens. According to Tseng(1943), it belonged to Section Forsterianae. On re-examining it, we found that in its longitudinal section of the stichidium, the sporangia are arranged at right angles to the central axis (fig. 9).According to Saito (1967), this species ought to belong to the Subgenus II Chondrophycus and Section Chondrophycus. Yamada (1931) regarded lenticular thickenings as a diagnostic character at the sectional level and distinguished the Section Forsterianae from the Section Laurencia of the Subgenus I Laurencia on the basis of the presence of lenticular thickening in the walls of the medulla. We are of the opinion that this characteristic should also have section bearing in the Subgenus II Chondrophycus and, therefore propose to establish a new section for L. articulata and L. verticillata as follows:关键词：LAURENCIA;XISHA ISLAND

发布时间：2023-04-28 - 摘要：So far, four species of Dictyotaceae have already been reported from the Xisha Islands,South China Sea, Zonaria nigrescens Sonder and Lobophora variegate (Lamx.) Womersley reported previously being synonymous with each other. The four species are Dictyota divaricata Lamx, D. friabilis Setchell, Padina australis Hauck and Lobophora variegata (Lamx.) Womersley. In the present paper, 12 species are reported, of which eight species are newly added to the flora of the Xisha, including one new species, namely, Padina xishaensis sp.nov. The other seven species are Dictyopteris repens (Okam. ) Boerg., Dictyota cervicornis Kuetz., D. patens J. Ag, Padina boryana Thivy, P. minor Yamada, P. jonesii Tsuda, Stypopodium zonale (Lamx ) Papenfuss. Among them, D. cervicornis, P. jonesii and S. zonale are recorded for the first time from China. These species are fully described on the basis of our own materials to facilitate better understanding of these seaweeds. The specimens studied including the type specimen are all deposited in the Herbarium of the Institute of Oceanology,Academia Sinica in Qingdao.关键词：DICTYOTACEAE;XISHA ISLAND

Eight species (Synedra rostrata, Podocystis adriatica, Navicula plicatula, N. pennata, N. pygmaea, Mastogloia pisciculus, M. quinquecostata, Amphora turgida )are new records for China.关键词：PENNATAE;XISHA ISLAND

发布时间：2023-04-28 - 摘要：Sea-grasses are aquatic plants completely adapted to live in the marine environments.The number of species of the Xisha Islands is rather small, about 3, belonging to 2 genera, namely, Thalassia hemprichii (Ehrenb.) Aschers, Halophila ovalis (R. Br.) Hook. and Halophila beccarii Asschers. They are all first records for Chinese water. In this paper, descriptions of the three species are presented.关键词：SEA-GRASSES;XISHA ISLAND

发布时间：2023-04-28 - 摘要：The present study is based on the collection from the Xisha Islands in May 1974 and April-may, 1975, of which 24 species are identified. With the exception of Collosphaera planca Su and Siphonosphaera arks Su, all are recorded for the first time from this investigation area.As the majority of these species have been described for the adjacent waters, we give only the description of those species which are first records for Chinese waters. Most of colonial radiolaria of the Xisha Islands are distributed in the surface waters.The frequency of occurrence of the different species varies. Some species as Otosphaera auriculata, Siphonosphaera polysiphonia, Acrosphaera spinosa, Collosphaera huxleyi, Siphonosphaera tenera, Solenosphaera pandora, and Solenosphaera zanguebarica are found at more than six stations, the rest at less than five stations or at only one station. Seven species are found in Jinyin Island and the northwestern part of the investigated area. As the colonial radiolaria of the Xisha Islands are mostly found in the surface waters,their quantitative distribution is closely related to the distribution of surface water temperature.关键词：COLONIAL RADIOLARIAS;XISHA ISLAND

A PRELIMINARY REPORT ON THE PHAEODARIAN RADIOLARIA FROM THE XISHA ISLANDS, GUANGDONG PROVINCE. CHINA
摘要：The material upon which this study was based was collected from the Xisha Islands by the Institute of Oceanology, Academia Sinica in May, 1975 and by the South China Sea Institute of Oceanology, Academia Sinica in May to June 1974 and in March to April, 1975.Nineteen species of phaeodarian radiolaria (6 uncertain ), belonging to 9 families and 14 genera, have been identified (see list of species in text). As the investigated region is limited to areas close to the Xisha Islands with depths not more than 1000 meters, the number of species found is very few and their occurrence is in low frequencies. Most of the species are warm water forms.关键词：PHAEODARIAN RADIOLARIA;XISHA ISLAND- 143
