History, Use, Propagation, Culture, 
2282. Mesogloia. From /xia-es, the middle, and yXoios, viscid : the spines of little branches radiating from a 
common centre, and forming what appears to be a solid mass. These plants were formerly referred to 
Ch£Btophora, from which they differ in the want of any fixed gelatine. 
2283. Batrachospermum. From (Sar^xxos, a frog, and <m^f^'/i. So called in allusion to the places in which 
the species grow ; they are mostly found in marshes, less frequently in the sea. 
2284. Draparnaldia. James Philip Ralph Draparnaud, was a French botanist, who wrote some memoirs on 
the subject of botany in the beginning of this century. He is also known for his acquaintance with fresh- 
water Conferva;.

oscillation of the filaments seems almost of an animal nature, although it frequently arises from mechanical
