the rearrangement of genericlines. Taking the species represented by 
Silene, Lychnis, and Agrostemma, he finds that there are two primary 
subdivisions based on whether the capsule is truly unilocular or has re- 
mains of dissepiments at base. The latter will include most species of 
Silene,and exclude S. noctifloraand S. Virginica, for which (with some 
species of Lychnis) Réhling’s genus Melandryum stands waiting. 
Further subdivisions are suggested, which are summarized in a table 
presenting no fewer than nine genera. This is surely at the other ex- 
treme from the view which would consider that all three allied species 
should be merged into one group. The nine genera suggested by Mr. 
Williams are Agrostemma, Lychnis (very much restricted), Coronaria (a 
Linnean genus revived to contain certain species usually referred to 
Lychnis), Petrocoptis (a genus founded by A. Braun to further circum- 
senbe Lychnis), Helio [ (a genus of Reichenbach founded for the 
same purpose), and Melandryum, all of which belong to the Lychnis- 
foup of unilocular capsules, The proposed genera of the Silene-group 
ue Vicaria of Rohling, Eudianthe of Reichenbach and Silene.
