Obs. It is possible that the record by Browne of R. pumilus Jlorihus 

 decidnis may refer to a form of this species, i.e. the var. suhapeialus, 

 Gren. et Godr. Fl. Fr. i. 37, in which the petals are much shorter than 

 the calyx, and sometimes abortive, which I have seen at Wytham. 



R. parvijlorus is found in all the bordering counties, but it is a rare 

 plant in Oxford and Bucks, and apparently decreasing.
