 der, really diftin6l I'pecies, and recommending to botanirts (ituated 

 on the fhores where they are found, to oblerve them carefully at 

 all feafons. It may be proper to notice, that the fpecimens which 

 have been found plentifully on the Norfolk coafl:, have all been o£ 

 the tuberculated fort; and that thefe have been but rarely met with 

 on the wcttcrn coaft, where the granulated fort is very frequent.

This elegant fpecies is diftinguilhed from fedoides by its more 

 rigid and patent branches, and by the fhape of its leaves, which 

 are more thinly fcattered below, but fomewhat crowded upwards. 

 It is farther diftinguiflied by the fru6lification, which confifts of
