Book excerpt: Excerpt from The Nature-Printed British Sea-Weeds, Vol. 2 of 4: A History, Accompanied by Figures and Dissections of the Algae of the British Isles; Rhodospermeae This fine species, both on account of the brilliancy of its colouring and the elegance of its form, is one of the most attractive and generally admired of our native marine ora. In size it is the largest of the genus, often reaching to the length of ten or twelve inches, but average specimens are not more than from four to six inches. Nor is it less common than beautiful, being found in almost every deep, shady rock pool on all our shores, larger and finer in deep, sheltered spots, where it is less liable to be torn by the storm, which its thin delicate fronds are but ill suited to resist, so that it is often no easy matter to find a large specimen free from laceration. In the month of May they may be found about half grown, quite entire, and the colours fresh and beautiful but as the summer advances they become more or less torn, and in autumn and winter are often cast on the beach in large bunches, con sisting of several dozens of fronds, and are then a tempting bait to the young algologist who may see the plant for the first time but no sooner has he commenced to analyse his prize than he finds every leaf split across to the midrib into innumerable narrow laciniae, consisting of one, two, or three veins, margined with a narrow membrane, the only remains of the frond. We have seen the frond occasionally divided at the summit, each portion being furnished with its correspondent division of the midrib, and Professor Harvey mentions a still more curious and extraordinary variety, having the frond divided in a manner between palmate and pinnate into several deep undulated lobes, whose apices are again lobed. These forms, however, are purely accidental, and may be often caused by some accidental injury done to the frond during the earlier stages of its growth.
