Turn (Fuci t Fucus E b t F sacchari)

fuci, t. 163. Fucus E. b. t. 1376. F. sacchari.

Eng. bot. t. 1331. Fucus 15325 15318 15322 15323 15327 History, Use, Propagation, Culture, 2317. Delesseria. The most beautiful of the Fucus tribe, so named in honor of M. Benjamin Delessert, a distinguished French patron of botany; and now holding the same station among the scientific men of Paris, as was lately occupied in London by Sir Joseph Banks. 2318. Lemanea. Named in honor of M. Leman, a French botanist, who possessed a considerable knowledge of Algæ. This genus is the puzzle of writers upon Algæ. It differs from all the Nostochinæ in its substance, being in no way gelatinous, and in its compound structure, and separate fruit; from Confervoideæ it is distinguished by its continuous frond, olivaceous color, and leathery texture. To Fucoideæ it most nearly related in color, substance, and structure, but it is akin to no other genus, and its habits are entirely different from those of Fucoideæ; the species being all found floating in fresh water. 2319. Chordaria. So called from the cord-like appearance of the species. 2320. Scytosiphon. The fronds of this genus are tubular and coriaceous; whence the name has been contrived, from σκuτoς, leather, and σiφωv, a siphon. ORD. VII. TRIBE V.

Sporochnus. The meaning of this word is not explained. The genus is remarkable for the nature of the reproductive organs, which consist of a minute receptacle formed by some clavate corpuscles, which are jointed and arranged in a concentrical manner, and crowned with tufts of hair. 2322. Haliseris. This name literally signifies sea-cabbage; from ἁλs, the sea, and σερiς, a sort of cabbage. The broad membranous fronds are not unlike the leaves of cabbage. 2323. Encœlium. From ev, within, and κoiλoς, hollow. The fronds are all tubular and bladdery. 2324. Zonaria. Beautiful marine plants marked with transverse zones of lines, in which the organs of reproduction are supposed to exist. 2325. Laminaria. The reproductive organs of this genus are situated in the form of large sori upon the lamina of the frond. L. esculenta is eaten in Scotland, where it is called Badderlocks. From L. saccharina, when dried in the sun, exudes a dry white sweetish substance, which is eaten as sugar by the poor inhabitants of Iceland. L. buccinalis furnishes the singular vegetable production called the sea-trumpet. 3 P CRYPTOGAMIA. 2326. LICHI'NA. Ag. LICHINA.
