 simple leafy. VAR. 2, cymo'sum, Moq. Tand. ; stems decumbent, leaves 

 more obtuse, cymes dichotomous leafless. Var. obtusifolittm, Syme. 

 ** Leaves more or less toothed or lobed. 



3. C. al'bum, L. ; erect, more or less mealy, leaves subentire or irregu- 

 larly toothed, upper oblong entire, sepals keeled covering the utricli- 

 narrowly scarious or all green, seed obtusely keeled or not. 



Waste places, especially in cultivated ground, ascending to near 1,000 ft. in

Sub-sp. FICIFO'LIUM, Sm. (sp.) ; flaccid, leaves more oblong-hastate with 

 broader obtuse spreading basal lobes, often contracted above them, spike* 

 " lax ascending panicled, seed not keeled. From Northumberland southwards, 

 Dublin and iJelfast, rare. Unlike any of the varieties of album proper ; 

 always easily recognized ; it should perhaps be regarded as a species, but 

 its distinctive characters are hardly to be conveyed by words.
