This has the fame habit, color, and fubftance as 

 the preceding, the leaf being"^ dichotomous 

 and ribbed throughout ; but it manifeflly differs 

 from it in the following refpefts ; — The edges 

 of the leaf have no ferratures, but are quite 

 intire — In the difc or furface are immerfed hol- 

 low fphsEiical or oval air-bladders, hairy within, 

 growing generally in pairs, but often fingle in 

 the angles of the branches ; about the fize of 

 large peafe or hazel-nuts ; which fome authors 

 fuppofe to be male-frudifications, but others, 

 with more appearance of truth, to be only air- 

 bladders deftined to buoy up the plant in the
