f. littorale, Host., receives with propriety a much wider range in 
Duval-Jouye’s mono. ; its ‘‘formes les plus saillantes” are 
gathered up into three vars.

* With this exception, Dr, Syme would apparently, if it turned up in Eng- 
land, place the inland form 7: tntermedium, Host, (=fide Duval-Jouve to 7: 
campestre, G. and G.) as a fourth var. y. under pungens. While out 0

Host. a cies by itself next to but distinct from 7. littorale.
