项目摘要

1.The following red algal species are new records from Malaysia and their characteristic morphological features are described (Botanica Marina, in press) : Hildenbrandia rubra (Hildenbrandiaceae), Kappaphycus cottonii, Solieria anastomosa (Sorieriaceae), Gracilaria multlfurcata, G. tenuistipitata, Gracilariopsis bailinitae (Gracilariaceae), Martensia australis, M. fragilis, Zellera tawallina (Delesseriaceae) and Herposiphonia pacifica, H. vietnamica, Neosiphonia flaccidissima, Polysiphonia scopulorum (Rhodomelaceae).2.A red alga Herposiphonia elongata Masuda et Kogame (Rhodomelaceae) is described as a new species (Cryptogamie, Algologie, in press).3.rbcL analyses of Japanese and Malaysian species of the red algal family Halymeniaceae indicate (Phycologia, submitted) : 1) the genus Halymenia is a well defined group and close to the genus Cryptonemia ; 2) Carpopeltis affinis, C. prolifera and Polyopes polyideoides are monophyletic and included in the Synkoraena clade ; 3) Samples of Grateloupia filicina from three geographical areas, Malaysia, USA, and Japan/China, may belong to three different species.4.Two novel sesquiterpenoids have been isolated from Laurencia pannosa (Rhodomelaceae) as halogenated secondary metabolites (in preparation).5.Taxonomic features of the following eight species of the brown algal genus Sargassum (Sargassaceae) were reported by Ajisaka et al. (1999): S. baccularia, S. binderi, S. cinereum, S. myriocystum, S. oligocystum, S. polycystum, S. siliquosum, S. stolonifolium.

1.以下是马来西亚新记录的红藻，描述了它们特有的形态特征（Botanica Marina, in press）：1 .红木兰花（Hildenbrandiaceae）、棉松果（Kappaphycus cottonii）、吻合丝瓜（Solieria sorriiaceae）、多花木兰花（Gracilaria mulfurata）、藤木兰花（G. tenuistipitata）、白木兰花（Gracilariopsis bailinae）、南木兰花（Martensia australis）、碎木兰花（M. fragilis）、花木兰花（delesseraceae）、太平洋木兰花（Herposiphonia）、越南木兰花（H. vietnamica）、新木兰花（Neosiphonia flassicissima）、东木兰花（Rhodomelaceae）。2 .红藻Herposiphonia elongata Masuda et Kogame （Rhodomelaceae）被描述为一新种（Cryptogamie, Algologie, in press）。日本和马来西亚红藻科Halymeniaceae物种的rbcL分析表明（phyologia，已提交）：1)Halymenia属是一个定义明确的类群，与Cryptonemia属相近；2) Carpopeltis affinis、C. prolifera和Polyopes polyideoides是单系的，属于Synkoraena支系；3)来自马来西亚、美国和日本/中国三个地理区域的菲律宾Grateloupia filicina样品可能属于三个不同的种。从桃金娘科（Rhodomelaceae）中分离到两个新的倍半萜类化合物，作为卤代次生代谢产物（正在制备中）。Ajisaka et al.（1999）报道了马尾藻属（马尾藻科）8种褐藻的分类特征：baccularia、S. binderi、S. cinereum、S. myriocystum、S. oligocystum、S. polycystum、S. siliquosum、S. stolonifolium。
