THE HA Y - S CEN TED BUCKLER FERN. 87 
over the whole surface, in two tolerably even lines 
along each pinnule or lobe. Indusia small and kidney- 
shaped, with uneven margins fringed by small round 
stalkless glands. The whole frond is covered with 
similar glands. By these stalkless, or sessile, glands, 
as well as by the fewer and narrower scales of the 
stipes, L. cemula is distinguished from L. dilatata — 
whose glands are stalked. In ordinary cases, the tri- 
angular outline and hollow crisped surface of the 
fronds are sufficient to distinguish the Concave Buck- 
ler Fern, which is also more decidedly evergreen, and 
has this further peculiarity, that the fronds decay from 
above downwards — not like the Broad Prickly-toothed 
Fern, upwards — from the base. Its range of elevation 
does not appear to exceed GOO feet. It prefers shady 
and rocky localities, and is easily cultivated.
