ing, the non-imbricate flowers and the very small anthers. These 

 points serve to distinguish the plant from the dwarf, starved pale- 

 yellow states of P. annua of our trodden path-margins and dry places. 



I am much indebted to Dr. O. Stapf for finally determining 

 the Jersey specimens ; he remarks: "It differs from the typical 

 Mediterranean form in having smaller, relatively stouter florets 

 with longer hairs." These characters will be useful to those who 

 separate the dwarf f. exilis from typical remotiflora.

III. The Genus Alsine. 



Since the appearance in this Journal (xxxvii. 317, 1889) of 

 Hiern's article on Alsine, there has been much uncertainty in the 

 minds of British botanists regarding the names of the plants which 

 are usually placed in the genus. Mr. Hiern, it will be remem- 

 bered, substituted Alsine (Hiern) for Spergidaria, and Minuartia 

 (Hiern) for Alsine (Gaertner). H. &. J. Groves, in their edition of 

 Babington's Manual (1904), adopted both of Hiern's substitutions, 

 although they retained a " suborder Alsinece " for a group of plants
