I take it that the International Eules, being retrospective in 

 their action, necessitate the adoption of A. sedoides Kittel. 



This is an Alpine species unknown in northern Europe : 

 there are very few members of the British flora which have such 

 a geographical range as this.

The chief points dealt with in this note regarding Alsine are 

 thus summarised : — 



(1) In the first edition of the Species Plantar itm (1753) of 

 Linnaeus there are two species of Alsine — A. media L. and 

 A. segetalis L. 



(2) Scopoli (1772) took the first of these as the type of his 

 Alsine] but as A. media L, is now universally recognised as a 

 Stellaria, the genus Alsine Scop, disappears. 



(3) Hiern (1899) took the second of the above species as the 

 type of his Alsine. Sometimes this species is placed in (S'^;cr- 

 (jularia, ^which is a nomen conscrvand um ; and thus ^4/si»c Hiern 

 is obsolete. By other authorities the species is placed in Delia, 

 and thus, judging by priority alone, Delia Dum. would become 

 Alsine Hiern emend. Schinz & Keller. 



(4) In the second edition of the Species Flantarum (i. 1762) 

 Linnteus added a third species of Alsine, A. mucronata L. 



(5) Gaertner (1799) took this third species as the type of his 

 Alsine, and was followed by Wahlenberg and almost all other 

 botanists. The name Alsine, as thus defined, is consequently 

 established firmly in botanical literature ; and, on this ground, it 

 is here suggested that the name be placed on the list of nomina 

 cojiservanda.

 McehringiaL., Bujfonia L., PolycarpumL., Alsine L. (partim), Arenaria L., and 

 Spergula L., but not Cherleria L.
