.WOODSIA HYPERBOREA 
WOODSIA HYPERBOREA (THE ALPINE WoonsıA) 
(Plate XL) 
The Woodsias, of which there are two species indigenous to Great 
: Britain, W. hyperborea and W. ilvensis, are both small-growing 
Ferns, rising from small, definite rootstocks in tufts. Our figures 
(318, 319), show both size and make, and obviate description, 
except that the fronds are somewhat hairy, and the spore capsules, 
which are in small round heaps, are protected by a fringed indusium,

quite distinct from any other genus. The species is rare; it has 
been found in Wales, but like W. ilvensis, which is the commoner of 
the two, most of the recorded finds have been in Scotland, and we 
have ourselves found it on Ben Lawers in Perthshire. Culture must 
be on the lines of the rock-loving species, with some broken porous 
stone mixed with open, well-drained soil. No varieties 
WOODSIA ILVENSIS (THE OBLONG WoonsıA) 
(Plate XL) 
Regarding this species, we have practically nothing special to 
add to our foregoing remark оп W. hyperborea, since the difference 
is indicated by the plates and illustrations.
