Filiform, slightly branched ; vesicles racemed. 

 This lias a dark coloured, tough, roundish, crooked stem, about nine- inches high, 

 having many crooked twigs very thick set, with bladders full of air, which are triang 

 roundish, haying an extant foliaceous membrane at top encircling it, and three other 

 extant alie underneath, appearing funnel-shaped", of a blackish-brown colour, when 

 dried, like glue, smelling strong of the sea, and of a saltish taste. It has several round 

 protuberances over its surface and grows on all the coasts of the island, or rocks co- 

 vered with the sea. Sloane.

Lenticula marina serratis foliis. Sloane, v. 1, p 59. Caidc terefi 

 ramossissimo, foliis oblongis serrato dentatis, vesiculis* globosis. 



Browne, p. 72. 

 Filiform, compressed, pinnate; leaves oblong lanceolate, serrate; vesicles 

 globular, peduncle?!, scattered, on flat dilated peduncles. 

 This is called the gulph weed, of which both Sloane and Browne make a larger and 

 smaller kind, which difference may probably be only occasioned by their being older and 

 younger plants They are very frequent in all the American seas, and often 

 thrown on the shores by high winds. 1 bey also grow on rocks. This is supposed to ho 

 the weed which was so plentiful in these seas as to retard the sailing ol Columbus's 

 ships; as well as *> there that have been obliged to cut their way through it. A.costasays; 

 it is eaten greedily By goats, and that it is good pickled. He also mentions a seaman 

 much troubled with sand and gross humours, who found relief front eating th.s weed 

 both raw and boiled.

. Caule tereti ramoso, foliis linearibus, iapsviis,foliolalis. Browjie, p.*72. 

 Filiform, branched; leaves linear, very entire ; vesicles globular peduncled. 

 This branched fucus, with capillary leaves, is frequently found in the British Channel, 

 and is distinguished from the foregoing, which it resembles very much in the general 

 form, by its simple capillary leaves. Browne. 



4. VESICULOSUS. BLADDERY. 



Linear, forked, entire, with globular, innate and axillary vesicles, cloven at 

 the lips, barren ones flat, fertile one tumid. 



The flat, divided, and marginated, fucus, with large spungy capsules, is commonly 

 called/;7/>, and frequent in most parts of Europe, but raretin Jamaica. When burnt, 

 it yields that concreted saline mass, ol" which our black or cosfrse glass is chiefly made.
