POTERIUM 195 



The Agrimony is too plentiful to need detailed localities ; it reaches 

 its maximum of frequency perhaps on the grassy borders of copses on the 

 chalk hills, and on the whole appears to prefer stiff soils to sandy and 

 gravelly situations. In damp woods and shady hedges it becomes 

 much more luxuriant, and is probably the var. sepium, Brebisson, 

 Flore de la Normandie, no. 



Agrimonia occurs in all the bordering counties.

 A. odorata has been recorded for all the bordering counties except 

 Bucks and E. Gloucestershire, but I have seen it in the former county 

 near Stoke Pogis. 



Obs. Altliough tlie extreme form appears to be fairly distinct from 

 ordinary A. Fupatoria, plants occur which are of an intermediate character. 

 Mr. Townsend, in Tlie Flora of Hampshire^ says that ' the furrows in the 

 fmit of A. odorata extend to the spines, and these are reflex. In A. Eupa- 

 toria, the furrows do not extend to the spines, and these are not reflex.' 

 Babington says that ' Eupatoria has the calyx tube furrowed to the base, 

 exterior sjpines spreading, odorata not furrowed, and exterior spines 

 declining.' Syme says 'that the furrows in odorata do not extend below 

 the raiddle of the tube.' The fruit of A. odorata visually has two achenes, 

 A. Eupatoria has usually only one. See Notes PI. Bares ou Critiques de la 

 Belg. fasc. i. 12 (1859).
