This species is represented in the collection by one plant only, which is clearly the 
same as that figured in Kiitzing’s Tab. Phyc. xi. t. 18. It seems to be closely allied to 
S. vulgare. Our plant is also exactly like a specimen in Herb. Kew, placed under the 
name Sargassum vulgare and labelled “Th. Kotschy, Pl. Pers. austr. Ed. R. F. 
Hohenacker, 1845. No. 805. Sargassum vulgare var. latifolium, Endl. et Dies.—Dies. 
Ad oram Karek, insulee sinus Persici. M. Jan. 1841.”
