In this Order there are a few plants which do not reach the south 
of England, and which are not very scarce in the central or in 
the northern parts of our island. Arabis petrea reaches no further 
south than Carnarvonshire and Merionethshire; this is also the 
case with Draba incana. D. rupestris is almost local: its south 
limit is Perthshire and Morayshire. Two of these species, and 
' perhaps the third, grow in the south of Europe; therefore it may 
be inferred that latitude is not the cause of their being limited to
