DIPLOPHYLLUM 261 
700 metres (Kaalaas). It is also a rare species in that 
country’s high latitudes. 
Grows in large or small light-green tufts, frequently 
covering rocks in moist districts, or scattered among other 
species, and is found on all formations, including limestone. 
Fruit, mature from April to June, is common, though 
sterile plants with perianths are abundant. Gemme are 
common. 
I have seen some hundreds of specimens of this species, 
and from every county. It is unnecessary to give localities, 
as on any day excursion, almost anywhere, one could 
hardly fail to meet with it. 
DiPLOPHYLLUM TAXIFOLIUM (Wahl.) Dwm. 
A rare species and confined to the higher mountains. 
As it is sometimes in mixture with D. albicans, it may be 
occasionally overlooked, but is rare even when allowance is 
made for this. It doubtless occurs, though sparingly, on 
most if not all our highest hills, as it has been found on 
those which have been most searched. It has been found 
to 3700 ft. alt. in the East Highlands and to 38600 ft. on 
Ben Nevis, and descending to 1800 ft. on the former and 
to 1700 ft. on the latter. Forms small green tufts on damp 
rock ledges or on bare soil, either pure or in mixture. 
Fruit has not been seen.
