and Miscellaneous Particulars. 
2321. 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 ocX?, the sea, and ffi^i;, a sort of cabbage. 
The broad membranous fronds are not unlike the leaves of cabbage. 
2323. Enccelium. From sv, within, and jcoiXo;, hollow. The fronds are all tubular and bladdery. 
2324. Zonaria. Beautiful marine plants marked with transverse zones of lines,- in which the organs of re- 
production 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.
