\» I. CLADOPHORA. 



289. Brownii (Brown's Cladophora); filaments forming dense, 

 cushion-like tufts, erect, rigid, flexuous, elastic, Blightly 

 branched; branches Few, Long, Bub-simple, Becund; axils 

 acute : articulations four or five tunes Longer than broad, the 

 Lower ones thickened upwards, the upper cylindrical, ffarv.

Cladophora glomerata, var.. Has*. Conferya Brownii, Dillw. 



C. pulvinata, /.'. Br. 

 Hah. In maritime situations exposed to the alternate inf 



of sail and fresh water; rare. Perennial. 

 Perhaps I transgress the true limits of a work on marine 

 Algae by including in it a plant which belongs as much to 

 the land as to tin' sea, and which is only occasionally wet 

 with Bea-water. The habit of Cladophora Brownii is that 

 of Vducheria terrestris ; a habit admirably expressed in 

 Mr. Brown's MS. name "pulvinata." It appears to bo 

 peculiar to the British Islands. 



290. repens {The mailed Cladophora): forming dense, cushion- 

 shaped or globular tufts; filaments Bhort, capillary, rigid, 

 densely matted together, rising from root-like fibres ; slightly 

 branched; branches erect, subsimple or forked., naki 

 with a few distant, Becund ramuli ; articulations cylindrical, 

 verv Long (ten to twenty times as Long as their diameter,

Conferva repens, J. Ag. CEgagropila simplex, Lenorm. 

 Hob. Jersey. Thrown on shore after a gale. Annual? Summer. 

 Ticked up by Miss Turner, on the beach at Jersey, after 

 a heavy gale, in 1846; four tufts only were found, and the 

 plant has not since been noticed. Though not one of the 



handsomest, this is one of the most curious species of the 

 genus. Outwardly it nearly resembles C. Brownii. hut the 



form and proportion of the articulations are very different. 



291. pellucida (77/' transparent Cladophora)] filaments rigid, 



t, setaceous, full dark -green, di-trichomotous 5 the axils 



very acute, the branches erect ; articulations many times 



ger than broad j dissepiments only at the forking of the 



branches and ramuli, Ktt. 1 G p. 271. (Atlas, PL
