Nemastome(d.'] irid^a. 215 



1. CllUORIA PELLITA, FHeS. 



Hab. On smooth exposed rocks and stones between tide- 

 marks. Fruiting in Pebruary. Perennial. 



Though this plant has not been very generally observed, 

 it is probable that it is widely distributed on our shores. 

 It is very common on the west coast, and I must have seen 

 it a hundred times, without ever thinking that it was a 

 plant, till it was named by Professor Harvey among other 

 things that I had sent for his inspection. My specimens 

 were chiefly found on the roots of Laminaria digitata, 

 which it often covers to some extent with a fine dark 

 brownish-red skin, like japan. It takes its specific name, 

 pellitaj from its shin-like appearance. It is well worth 

 while to consult Phyc. Brit., PI. cxvii., where it is analysed, 

 for it is surprising to see the curious filaments of which 

 this sJcin is composed.
