bling a comb in form. Thefe teeth, when the plant is dried anddif- 

 played, give it fomething of a reticulated appearance, and probably^ 

 induced Gmelin to adopt the not very appofite name oi plocatnium. 



The fruftification confifts of minute tubercles fcarcely fo large 

 as muftard feed, for the mofl part feflSle, it being very rare to meet 

 with one fupported on a peduncle^ affixed to tlie fides of the fmaller 

 branches in confiderable quantity, but always fingle, and when 

 filled with ripe feeds nearly black. We have obferved, on fome fpe- 

 cimens, tubercles fomewhat larger, of the fame colour as the frond, 

 and always empty. Whether the plant be dioecious, and this the 

 male frudlifieation, muftbe left to future enquiry. 



When old, or expofed on the beach, the colour is frequently pala 

 yellow or white intermixed with the red; but when young and vi- 

 gorous, it is never feen of any other colour than bright red ap- 

 proaching to fcarlet, and the mofl: brilliant of any of the genus : 

 when dried, this changes to a purplifh red. 



It is found on every part of the Britilh coaft:, and is very often 

 parafiticalon other plants, particularly the larger Futi. — We have 

 obferved it on vejfculofus ?j\d. fibrofusy and alfoon crifpus. — When in 

 this fituation it frequently forms thick tufts not exceeding an incb 

 in height, and might eafily be raiftaken for a different plants
