Obs. — Being destitute of stipules this plant is at once distin- 

 guished from those British species which have them. 



Lej. calcarea, Libert, and Lej. Rossettiana, Massal. have 

 ecliinate leaves. 



Lej. microscopica, Tayl. has more spreading, narrower leaves, 

 and is rarely found fertile.
