Woodsia obtusa


A frond of blunt-lobed woodsia. Note the blunt tips of the leaflets and the wide spacing between lower leaflets.


Underside of a frond, showing the sori (spore-bearing structures).


Close-up of the sori. They are initially covered by a disk of thin tissue, which tears open, leaving the papery remnants visible here.
