weeds collected in that neighbourhood diu-ing the past summer, we were 

 pleased to find numerous specimens of various Algse, such as Polysi- 

 pJionia nigrescens, Jihrata, and elongata, quite shaggy with the present 

 species, growing in large matted tufts, of a fine orange brown colour. 



We have not the least doubt but that the plant is abundant in the 

 inner basins at least of the Moray Frith. It is singular, however, that no 

 appearance of fructification was observed on any of the specimens, which 

 would appear to be very rare. We hope, however, that some of our 

 numerovis friends in that quarter may yet succeed in finding it. 



The uncertain appearance of the fruit of some plants, as well as of 

 the plants themselves, is a curious circumstance, and one not yet satis- 

 factorily explained. It is one, however, of great interest, and which we 

 should like to see more carefully investigated. 



We have often had occasion to notice it, both among flowering plants 

 and Cryptogams, and in both many cmious instances of it have come 

 under our observation.
