南极海洋植物区系：独特地缺乏海藻

对常见的大型南极棕色海藻Himantothallus胚胎期的发现导致了这样的结论：这种迄今被模糊地归入海带目(海带)的植物是海带目的一员。此外，对Himantothallus和另外两种神秘的褐藻--Phyllogigas和Phaeoglossum--的大量实地研究，导致了这三个属的合并，并识别出一个单一的种--Himantothallus Grand difolius。这些类似海带的藻类的正确放置突显了南极海洋植物群的独特性，因为它是唯一没有海藻的冷水植物群。
The discovery of embryonic stages of the common large Antarctic brown seaweed Himantothallus has led to the conclusion that this plant, hitherto assigned equivocally to the Laminariales (kelps), is a member of the Desmarestiales. Moreover, field study of a large sample of Himantothallus and two other enigmatic brown algae, Phyllogigas and Phaeoglossum, has led to the merger of these three genera with the recognition of a single species, Himantothallus grandifolius. The correct placement of these kelp-like algae underscores the uniqueness of the Antarctic marine flora as the only cold-water flora without kelps.
