234 BiuTisH SEA-WEEDS. \_lUiodosj)erm€ce. 



by the Rev. Mr. Smithy of Borguc, I tliouglit I had got the 

 southern Grateloiipia filicina. Tor good figures and de- 

 scriptions, see 'Algre Britannicfc/ PL xv., and 'Phycologia 

 Britannica/ PL liii. Dr. Greville describes about fourteen 

 varieties. The prettiest variety I have ever seen has been 

 sent to me by Mrs. Tyers_, near BristoL The branches are 

 capihary, and the ramuli are " in the form of inversely lan- 

 ceolate or ovate leaves, much attenuated at their insertion." 

 It is the var. clavatum of Dr. Greville. 

 ■^ 2. Gelidium caetilagineum, Greville, 

 Hab. On rocks in the sea. Perennial. 

 A magnificent plant, but a very doubtful native. The 

 frond is from ] 2-18 inches long ; the colour is a dark pur])le, 

 but when it begins to be decomposed it is shaded with 

 fine tints of scarlet, orange, yellow, and green. I remember 

 seeing a good specimen framed as a painting, and exposed 

 for sale in the Cowgate of Edinburgh. I procured two 

 specimens of it from Dublin, where, on dit, it is occasionally 

 found in the bay. I learn from Professor Harvey that it 

 has lately been cast ashore at Kyde. Through the kindness 

 of Professor AValkcr Arnott, I have a few specimens of it 

 from Brodie's Alg. Herb.
