本文根据古海洋学的限制和最近的实验结果，特别是耐温性和杂交研究的结果，概述了层压带的阶内关系。在海带的指状部分，有证据表明，当白令海陆桥在上新世被淹没时，至少有两个太平洋祖先通过白令海峡和北极海岸入侵北大西洋。有一个来自太平洋的单一共同祖先被假设为具有刚性柱头的物种，目前在北太平洋的代表是L. setchellii，在东北大西洋的代表是L. hyperborea和L. ochroleuca，在非洲南部的代表是L. pallida和L. schinzii。第二种来自北太平洋的外来物种，具有与北太平洋L. bongardiana （= L. groenlandica sensu Druehl 1968）相关的灵活茎杆，被认为是北大西洋L. digitata和两个西南大西洋深水物种L. brasiliensis和L. abyssalis的祖先。
The present paper outlines within order relationships of the Laminariales on the basis of paleoceanographic constraints and recent experimental results, especially those dealing with temperature tolerance and hybridization studies. Within the digitate section of Laminaria, it is suggested that at least two Pacific ancestors invaded the North Atlantic via the Bering Strait and the Arctic coasts when the the Bering Land Bridge became submerged during the Pliocene. A single common ancestor from the Pacific is hypothesized for species with a rigid stipe as currently represented in the North Pacific by L. setchellii, in the northeastern Atlantic by L. hyperborea and L. ochroleuca, and in southern Africa by L. pallida and L. schinzii. A second immigrant from the North Pacific with a flexible stipe related to the North Pacific L. bongardiana (= L. groenlandica sensu Druehl 1968), is hypothesized to be ancestral to the North Atlantic L. digitata, and the two southwestern Atlantic deep-water species L. brasiliensis and L. abyssalis.
