HAPLOZIA Lay 
streams and sometimes in marshes, but is most common 
near the base of the hills. It is uncommon above 2000 ft. 
alt., though ascending to 3200 ft. in Mid Perth. This 
species does not show any particular preference for lime- 
stone in Scotland, as it is stated to do on the Continent. It 
appears to be a commoner plant with us than in other parts 
of Europe, and limestone is a rare formation in this country. 
It grows in dark olive-green or dirty green tufts, or in 
thin creeping patches on wet rocks. In the latter case it is 
sterile, but in its usual compact state fruit is common, and 
is mature from March to June and occasionally to August. 
Perianths are usually present at all times of the year. 
The var. potamoplhila is here intended for the large form 
with somewhat the appearance of H. cordifolia.
