168 Dr. G. Dickie on the Fructification of Cutleria. 



might have been led to conjecture that they were only the com- 

 mon capsules in an immature state, had they not been on the 

 plants that bore granular fruit, and had I not found it stated in 

 Harvey's f Manual/ that the two kinds of fructification, capsules 

 and granules, are on distinct plants. It is fair to state however 

 that I have observed two granules, and only two, in one of the 

 ramuli of a plant with the large dark-coloured capsules, so that 

 it may turn out that where the granules abound the capsules are 

 dwarfed, and that where there are scarcely any granules in the 

 branches and ramuli, there the capsules swell and are perfected. 



I must now conclude my lengthy note. I am glad of anything 

 that attracts attention to this beautiful little Polysiphonia.

XXI. — Note on the Fructification of Cutleria. By G. Dickie, 

 M.D., Lecturer on Botany in the University and King's Col- 

 lege of Aberdeen*. 



The results of observations which have already been communi- 

 cated to the Society on the fructification of the Algae found in 

 this vicinity, led to an examination of other genera not growing 

 here, but of which I possess dried specimens ; and at present re- 

 ference is specially made to Cutleria multifida, Grev. In Harvey's 



1 Manual/ Dr. Greville's account of the fructification is quoted, 



viz. " minute tufts of capsules scattered on both sides of the frond ; 



the capsules pedicellate, containing several distinct granules." I
