The macroalgal flora of Graciosa (central group of Azores archipelago) is poorly known, with only 116 species recorded so far (authors personal data). The published information reflects occasional collections from sporadic field visits to the Island. To overcome this, a thorough investigation under the Expedition "GRACIOSA/2004", the Campaigns "PADEL/2006", "MACROBIOLMOL/2014" and "PIMA-BALA/2017" involving sample collecting and presence data recording, was undertaken over an area of 19 km encompassing littoral and sublittoral levels down to about 40 m around the Island. This paper lists the taxonomic records and provides information on species ecology and occurrence around the Island improving the knowledge of the Azorean macroalgal flora at both local and regional scales.
A total of 1692 specimens belonging to 250 taxa of macroalgae (and including 55 taxa identified only at the genus level) are registered, comprising 166 Rhodophyta, 36 Chlorophyta and 48 Ochrophyta (Phaeophyceae). From these, 195 are identified to the species level (126 Rhodophyta, 31 Chlorophyta and 38 Ochrophyta) and comprise 156 native, 20 of uncertain origin and 14 introductions to the Island. Predaea feldmannii subsp. azorica Gabriel is an Azorean endemic, whereas O.C. Schmidt, Afonso-Carrillo, Sobrino, Tittley & Neto, P.Crouan & H.Crouan ex Karsakoff and Gil-Rodríguez & Haroun represent Macaronesian endemics. Seventy-nine species are newly recorded to the algal flora of the Island.
格拉西奥萨岛（亚速尔群岛中部组）的大型海藻区系鲜为人知，迄今为止仅记录了116种（作者个人数据）。已发表的信息反映了对该岛进行零星实地考察时的偶然采集。为克服这一情况，在“格拉西奥萨/2004探险”、“PADEL/2006活动”、“MACROBIOLMOL/2014活动”和“PIMA - BALA/2017活动”中，对该岛周围19公里的区域进行了全面调查，涉及样本采集和存在数据记录，范围包括沿岸和亚沿岸区域，深度达约40米。本文列出了分类记录，并提供了有关该岛周围物种生态和分布情况的信息，提高了对亚速尔大型海藻区系在地方和区域尺度上的认识。
共记录了属于250个大型海藻分类单元的1692个标本（包括仅鉴定到属级的55个分类单元），其中包括166种红藻、36种绿藻和48种褐藻（褐藻纲）。其中，195种被鉴定到物种水平（126种红藻、31种绿藻和38种褐藻），包括156种本地物种、20种来源不确定的物种和14种引入该岛的物种。费尔德曼氏前沟藻亚亚种加布里埃尔藻是亚速尔群岛特有种，而施密特氏藻、阿方索 - 卡里略藻、索布里诺藻、蒂特利藻和内托藻、库罗安氏藻和哈伦氏藻代表马卡罗尼西亚特有种。79种为该岛海藻区系新记录物种。
