ABSTRACT The tetrasporophytic ‘Trailliella’ stage of the red algal genus Bonnemaisonia is reported for the first time from the Southern Hemisphere. Here we describe a bloom of the tetrasporophyte of B. hamifera from the mouth of the Waikouaiti River, Karitāne, South Island, where it occurred as thousands of free-floating tufts up to 1 cm wide in shallow water, accumulated in windrows on sand banks and beaches, and in the water column at depths of 10–12 m on the adjacent open coast. Gametophytic stages have not yet been found in New Zealand. The material collected to date is strictly vegetative, and reproduction occurs via fragmentation. The identity of the New Zealand samples as B. hamifera was confirmed by both morphology and rbcL sequencing. The abundance and floating dispersal of B. hamifera suggests that it is invasive and will become widely distributed in New Zealand.

Bonnemaisonia hamifera (Bonnemaisoniales, Rhodophyta) 在南太平洋的第一个记录，来自新西兰南岛

摘要 南半球首次报道了红藻属 Bonnemaisonia 的四孢子体“Trailliella”阶段。在这里，我们描述了来自南岛 Karitāne 的 Waikouaiti 河口的 B. hamifera 的四孢子体的盛开，它在浅水中形成了数千个自由漂浮的 1 厘米宽的簇，堆积在沙岸上的草丛中和海滩，以及相邻开阔海岸 10-12 m 深处的水柱中。在新西兰尚未发现配子体阶段。迄今为止收集的材料严格来说是植物性的，繁殖是通过碎片进行的。通过形态学和 rbcL 测序确认新西兰样品为 B. hamifera。B. 的丰度和浮动扩散。
