Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1905 edition. Excerpt: ...covers large areas with an almost unmixed growth of its characteristic alga. It would therefore look very uniform but for the very luxuriant subvegetation of epiphytes, mainly the Florideze. It is the haptera and especially the stalk which are almost densely covered by large or small alga (see fig. 161). The lamina however is mostly destitute of epiphytes, most likely because it is changed every year. Various species, however, e. g. Rhodymenia palmata, Ectocarpus tomentosoides, which would probably be very common in spring, E. tomentosus, E. fasciculatus, and some others, may be found growing on the lamina, especially in shallow water. Among the many epiphytes that grow on the stalk and the roots, the following species may be pointed out: Polysiphonia urceolata, Chantransia Daviesii, Callophyllis laciniata, Euthom rristata, Rhodophyllis dirhotoma, Lomentaria clavellosa, L. rosea, Plocamium coccineum, Delesseria alata, D. sinuosa, D. sanguinea, Polysiphonia elongata, Odonthalia dentala, Plilota plumosa, Pt pectinata, Antithamnion /Ioccosum, Ceramium rubrum, Rhodochorton Rothii, Cruoria pellita, Lithophyllum Crouani, Dermatolithon macrocarpum f. Laminariw, Peyssonelia Dubyi, Sphacelaria furcigera, Desmarestia aculeata, D. viridis; that is to say, scarcely any but Florideaz. Most of these epiphytes may be found even in rather shallow water in the semidarkness under the Laminariaz which also afford some protection from the violence of the waves. In describing the alga-vegetation of the Mediterranean Sea, Berthold points out (5, p. 422) that the epiphytes on a Cystosira granulata grow in a certain fixed order. Those that require more light grow on the top of the Cystosira, those that want less grow under the latter. The epiphytes on the stalks...show more
