Gloiocladia.'] nemalion. 209 



and of a richer brown colour, than any I have seen from 

 other localities. It seems a northern plant. About the 

 month of September it is got in beauty at Whiting Bay in 

 Arran.

1. Nemalion mtjltifidum, J. Agardh. 



It somewhat resembles Bumontia Jiliformis. Though 

 said to be not uncommon, we have never gathered it, and 

 the only specimen we have is from the Eev, AY. S. Hore. 



2. Nemalion puhpureum, Uarv, This was formerly 

 Mesogloia purpurea. It has been found by Mrs. Griffiths 

 and by Miss Cutler. Most beautiful specimens have lately 

 been found by Mrs. Gulson at Exmouth, some of which 

 she has sent to me, along with a drawing of the largest 

 she ever found. It is magnificent — like a noble gnarled oak 

 that had stood the wintry blasts of hundreds of years.
