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 Algse. This genus is the puzzle of writers upon Algae. It differs from all the Nostochinae in its sub- 
stance, being in no way gelatinous, and in its compound structure, and separate fruit ; from Confervoidese it is 
distinguished by its continuous frond, olivaceous color, and leathery texture. To Fucoideaj 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 Fucoideae ; 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 con 
trived, from irzvroi, leather, and <r«pav, a siphon.
