Among European ae ecies seems nearest C. Orbelicum and C. 
Apuanum in specific charact ters. I know of no other species of 
Cerastium from these islands. Some specimens collected many 
were referred rs C. campanulatum, but they prove on 
exam to belong to this species lave examined 
drawn up a fresh description. These specimens represent all the. 
three forms mentioned by Seubert. The other specimens in Herb. 
Kew. were raised rete seed by Mr. H. C. Watson, and are not so 
cronmgeg k though they are readily recognizable from the figure 
y Seubert.
