The Erigeron Acre is by no means a common plant in our neighbourhood, yet occurs very frequently 
on the hilly and chalky ground about Charlton Wood, particularly in the chalk pits on the left hand fide of 
the lane behind the Church. 
It flowers in the months of Auguft and September, and is confidered as a pretty fure indication of a barren foil. 
It has a tafte fomewhat warm and biting, and hence has received its name of Acris. 
We have rather chofen to retain Linnaeus’s name of Erigeron than adopt Ray’s name of Fleabane, which 
tends to confound it with the Genus Conyza. 
It frequently grows much taller, and is often found much fmaller than the fpecimen we have figured.
