“In the lowest pools the Laminarias begin to appear, called variously the oarweeds, devil’s aprons, sea tangles, and kelps. The Laminarias belong to the brown algae, which flourish in the dimness of deep waters and polar seas. The horsetail kelp lives below the tidal zone with others of the group, but in deep pools also comes over the threshold, just above the line of the lowest tides. [...] To look into such a pool is to behold a dark forest, it’s foliage like the leaves of palm trees, the heavy stalks of the kelps also curiously like the trunks of palms. [...] One of these laminarian holdfasts is something like the roots of a forest tree, branching out, dividing, subdividing, in its very complexity a measure of the great seas that roar over this plant.”
