represents more than an abnormal form of C. i-anescens, monoecious 

 individuals occurring, though rarely, in other dioecious species, 

 e.g. ('. frwiifera: C c.vceha, Allen, a plant belonging to the 

 cuntraria group, apparently nearly allied to the European (.'. 

 stri(/ot;a, Brauii, from which it differs by its fewer spine-cells and 

 less regular cortication. Descriptions and figures are also given 

 of C. crinita {('. caneHcens), C. aspera, and var. Macowiii (var. nov.), 

 and ('. frfufilis. 



In the second paper nine forms of " Chara coronata " are 

 described, with magnified figures of their fi-uctification. Dr. Allen 

 follows Braun's later views in thinking that, as the variation of 

 this and other species of Chara is so complex, it is desirable to 

 characterise the forms by a string of adjectives instead of a varietal 

 name. It is difficult to understand why Brauu adopted the name 

 of C. coronata; it was described as C. Brainiii by Gmelin in 1826, 

 whereas the name of C. coronata was not introduced by Braun 

 until 1834, and in ' Characeen Afrika ' Braun quotes it as of " Ziz. 

 ined. circa annum 1814 (sensu latiori)"; certainly there was no 

 doubt as to the species intended by Gmelin. We think that even 

 those who do not care for accuracy in nomenclature might adopt 

 the name of C. Braunii in honour of the greatest authority on 

 this order. 



Dr. Allen has discontinued the publication of his ' Characeas 

 Americanae ' and ' Charace^ of America ' and purposes from 

 time to time issuing, in their place, descriptions and figures of 

 new American species. We are glad to see that he is continuing 

 the issue of his fasciculi, of which he has now reached the third 

 part. H. & J. G.
