ANOTHER KIND OF FALSE FRUCTIFICATION. 7 



with coloured joints, in all respects resembling those 

 that form the periphery, but much longer. 



To the naked eye, these warts often resemble capsules, 

 and as such have been frequently described ; but they 

 never contain any seeds. 



Another anomalous body, simulating fruit, frequently 

 occurs in some of the filamentous tribes, especially in 

 the genus Polysiphonia, and in the species P. fibrata, 

 P. fibrillosa, and P. fastigiata, to which Agardh has 

 given the name of aniheridium. It is a very minute 

 pod-like or lanceolate body, of a yellow colour, contain- 

 ing a granular fluid, borne on the colourless, long-jointed 

 fibres that are found, at particular seasons, issuing from 

 the tips of the branches in several, if not all, of the Po- 

 lysiphoniad. The nature of these minute organs, it is 

 thought by Dr. Harvey, deserves more attention than 

 it has obtained ; for he says, " I am strongly of opinion 

 that they are produced with too much regularity to be 

 regarded as accidental." 



After the foregoing observations, chiefly taken from 

 Dr. Harvey's Manual, and which are introduced with the 

 intention of affording to the young algologist some use- 

 ful information of a general character, I now proceed to 

 the practical part of the subject, by endeavouring to 

 explain, as clearly as I am able, the best manner of col- 

 lecting marine Algae, and of afterwards preserving them. 

 Having already stated that this has been a favourite
