Lycopodium inundatum, Linneus. 
The Marsh Club-Moss appears to occur, although not abun- 
dantly, on most of the heaths and commons in the south of 
England, particularly where turf has been pared from the sur- 
face. The localities are far too numerous to detail. In the im- 
mediate neighbourhood of London many habitats have been 
recorded. In the midland and northern counties it is less com- 
mon ; in Scotland and Wales it is of comparatively rare occur- 
rence ; and in Ireland it is altogether unknown. It is found on 
wet or turfy ground, generally preferring a sandy or gravelly 
soil : its non-appearance in Ireland seems rather extraordinary. 
It exhibits the same predilection for flat and low situations which 
most of the other species display for elevated and hilly districts, 
so that it is very rarely found in company with either. 
Our early botanists were not generally acquainted with this
