with it, Rubia peregrina, Ophrys muscifera, and O. apifera grow 
together, at little above sea-level, and associate with the corn crops 
of Watson’s ‘agricultural zone.” So that it becomes difficult to 
say whether we are dealing with alpines descending into the agri- 
cultural zone, or with plants of the lowest agricultural zone in a 
very abnormal association. At any rate, we have here a commixture

Trish climate, as well as to past geological changes and migrations. 
All the West Irish plants may be considered as species which
