Flowers and fruit of the seagrass Halophila ovalis subsp. bullosa (Setchell) Hartog are reported from the Nasese intertidal flats, Laucala Bay, Fiji Islands, and described for the first time. The observation of pistillate and staminate flowers completes the flowering event reporting of this endemic Fijian taxon, and also resolves its taxonomic identity. Lack of prior descriptions of H. ovalis subsp. bullosa flower and fruit may be a consequence of the small size of the flower and fruit structures, which may be easily overlooked during field studies. Our descriptions confirm that H. ovalis subsp. bullosa in Fiji is a dioecious seagrass, and that its reproductive features are identical to those of H. ovalis. The reproductive features observed, therefore, provide no evidence for subspecies designation of H. ovalis subsp. bullosa. Description of the sexual reproductive structures of H. ovalis subsp. bullosa is important in species discrimination, field identification, and to provide further precision in seagrass ecological investigations.

寄养和雌蕊花椭圆形亚种的花和果实。Bullosa(Setchell)哈托格

海草椭圆形椭圆形亚种的花和果实。松解症(瑟特查)哈尔托赫从Nasese潮滩,Laucala湾,斐济报告,并且首次描述。观察到的雌蕊和雄蕊花完成了该地方性斐济分类单元的开花事件报告,并解决了其分类学特征。缺乏对卵形嗜血杆菌亚种的先前描述。花和果实可能是花朵和果实结构较小的结果,在田间研究中很容易忽略。我们的描述证实了卵形嗜血杆菌亚种。布洛萨斐济的雌雄异株是海藻,其繁殖特征与H相同。卵圆形。因此,观察到的生殖特征没有为H的亚种指定提供任何证据。卵圆形亚种 大疱H的有性生殖结构的描述。卵圆形亚种 Bullosa在物种识别,田间识别以及在海草生态调查中提供进一步的精确度方面都很重要。
