Abstract

St. Martin’s Reef (SMR) about 14 km west of the St. Martin’s Island, Teknaf, Cox’s Bazar, Bangladesh was not known during last over 50 years of seaweed researches. Recent six collections made with the assistance of Bangladesh Navy revealed 8 seaweeds species which are Pterocladiella maribagoensis Boo and Geraldo, Hypnea spinella (C. Agardh) Kützing, Peyssonnelia polymorpha (Zonars.) Schmitz, Jania pumila Lamx., Jania ungulata f. brevior (Yendo) Dawson (Rhodophyta); Caulerpa racemosa var. clavifera (Turner) Bosse, Bryopsis plumosa (Huds.) C. Ag. and Halimeda tuna (Lin.) Lamx. (Chlorophyta). Of these six seaweeds such as Pterocladiella maribagoensis Boo et Geraldino, Hypnea spinella (C. Agardh) Kützing, Jania pumila Lamx., Jania ungulata f. brevior (Yendo) Dawson, Bryopsis plumosa (Huds.) C. Ag. and Halimeda tuna (Lin.) Lamx have been newly recorded and described from the SMR in Bay of Bengal (Bangladesh territory). Presence of Peyssonnelia polymorpha and Bryopsis plumosa in the collections and physical and chemical water environments recorded indicated it as a true newly forming reef. The present illustrated account is however may be considered as base-line information on seaweed flora of the new SMR in the North-east Bangladesh coast. A total of six seaweeds have been newly recorded making the total seaweeds to 215 mostly from the SMI and nearby SMR. Bangladesh J. Plant Taxon. 30(1): 153-163, 2023 (June)

孟加拉圣马丁礁的海藻群

在过去50多年的海藻研究中，孟加拉国科克斯巴扎尔Teknaf圣马丁岛以西约14公里处的圣马丁礁（SMR）并不为人所知。最近在孟加拉国海军的协助下进行的六次收集揭示了8种海藻，它们是Pterocladiella maribagoensis Boo和Geraldo、Hypnea spinella（C.Agardh）Kützing、Peyssonnelia polymorpha（Zonars.）Schmitz、Jania pumila Lamx。，Jania ungulata f.brevior（Yendo）Dawson（Rhodophyta）；外消旋Caulerpa raceosa var.claifera（Turner）Bosse、羽藻Bryopsis plumosa（Huds.）C.Ag.和Halimeda金枪鱼（Lin.）Lamx。（绿藻门）。在这六种海藻中，如Pterocladiella maribagoensis Boo et Geraldino、Hypnea spinella（C.Agardh）Kützing、Jania pumila Lamx。，Jania ungulata f.brevior（Yendo）Dawson、Bryopsis plumosa（Huds.）C.Ag.和Halimeda tuna（Lin.）Lamx是在孟加拉湾（孟加拉国领土）的SMR中新记录和描述的。在采集的标本中以及记录的物理和化学水环境中，多晶佩松藻（Peyssonnelia polymorpha）和羽藻（Bryopsis plumosa）的存在表明它是一个真正的新形成的珊瑚礁。然而，本说明可被视为孟加拉国东北海岸新SMR海藻区系的基线信息。新记录的海藻共有6种，使海藻总数达到215种，主要来自SMI和附近的SMR.Bangladesh J.Plant Taxon。30（1）：153-1632023（六月）

期刊介绍： Bangladesh is a humid, subtropical country favouring luxuriant growth of microorganisms, fungi and plants from algae to angiosperms with rich diversity. She has the largest mangrove forest of the world in addition to diverse hilly and wetland habitats. More than a century back, foreign explorers endeavoured several floral expeditions, but little was done for non-vasculars and pteridophytes. In recent times, Bangladesh National Herbarium has been carrying out taxonomic research in Bangladesh along with few other national institutes (e.g. Department of Botany of public universities and Bangladesh Forest Research Institute).
