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.以下红藻物种是来自马来西亚的新记录，并描述了它们的特征形态特征（Botanica Marina，印刷中）：Hildenbrandia rubra（Hildenbrandiaceae），Kappaphycuscottonii，Solieria anastomosa（Sorieriaceae），Gracilaria multlfurcata，G. tenuistipitata，Gracilariopsis bailinitae (Gracilariaceae), Martensia australis、M. fragilis、Zellera tawallina (Delesseriaceae) 和 Herposiphonia pacifica、H. vietnamica、Neosiphonia flaccidissima、Polysiphonia scopulorum (Rhodomelaceae)。 2. 红藻 Herposiphonia elongata Masuda et Kogame (Rhodomelaceae) 被描述为新种 (Cryptogamie、 Algologie，出版中）。3.对日本和马来西亚红藻科 Halymeniaceae 物种的 rbcL 分析表明（Phycologia，已提交）：1) Halymenia 属是一个定义明确的类群，与 Cryptonemia 属接近； 2) Carpopeltis affinis、C. prolifera 和 Polyopes polyideoides 是单系群，属于 Synkoraena 进化枝； 3) 来自马来西亚、美国和日本/中国三个地理区域的Grateloupia filicina 样品可能属于三个不同的物种。4. 从 Laurencia pannosa (Rhodomelaceae) 中分离出两种新型倍半萜类化合物，作为卤化次生代谢产物（制备中）。 5. Ajisaka等人报道了以下8种褐藻属马尾藻属（马尾藻科）的分类学特征。 (1999)：S. baccularia、S. bonderi、S. cinereum、S. myriocystum、S.oligocystum、S.polycystum、S. siliquosum、S. stolonifolium。
