the pedicels, combined with the cylindrical, exactly linear fruit. 

 S. racliciformis alone approaches it in the length of the pedicel, 

 but differs completely in the form of the fruit, which in that 

 species is globose. 



JS. Moorei was discovered by Charles Moore, Esq., the able 

 curator of the Sydney Botanic Gardens, and deservedly bears 

 his name. It is the only species hitherto found at Port Jackson, 

 and is abundant toward the eastern end of Spectacle Island, 

 in the same locality where Claudea Bennettiana, the rarest of 

 Australian Algse, was once dredged. 



Like all others of the genus, it rapidly becomes flaccid and 

 changes colour when exposed to the air. When growing in a 

 strong current, its branches are very much drawn out, and less 

 crowded than is represented in our figure. 



Tig. 1. Spokochnus Moorei ; a branch, — of the natural size. 2. A young 

 receptacle; and 3, one further advanced. 4. Transverse semi-section of a 

 receptacle. 5. A paranema or spore-filament from the same, bearing spores: 

 — the latter figures magnified.
