924 CRYPTOGAMIA ALGi^. 



fubulate leaves, refembling dents or fpines, a 

 little incurv'd. The inferior branches are alfo 

 furnirtied with the fame kind of leaves or 

 fpines, but they are moft frequent towards the 

 extremities. 



Such is the defcription of the unfruftified plant j 

 but in a ftaie of frudification, it affumes a 

 different appearance. The ftalks in the fecond 

 and third divifion of the branches become then 

 inflated in the middle with fmall oblong vefi- 

 cles or air-bladders, placed at a little diftance 

 two, three, or four one above another, like 

 beads on a necklace ; each of which veficles 

 has commonly one or two of the fore-mentioned 

 fubulate leaves or fpines growing upon it. 



The extremities of the branches alfo, which be- 

 fore were very narrow, and a little comprefs'd, 

 now become tumid and fubulate, covered all 

 round with numerous frudliflcations, crowded 

 together like fmall warts, each with a pundure 

 in the centre, and within full of feeds. Thefe 

 tumid extremities ftill retain their fpine-like 

 leaves growing out of their fides, as before they 

 were fructified.
