Large course ferns which often grow from underground rootstocks,
and therefore occur in extensive patches. The fronds are leathery
These were growing in a large patch under the shade of an aspen
Several species of small ferns may be found growing from cracks
in large rocks and cliffs. Here are two kinds growing
together. The one with the typical fern-like fronds is
the Parsley Fern or Rock-brake (Cryptogramma crispa).
The other one is Brewer's cliffbrake (Pellaea breweri).
It appears to have leaves similar to those of a flowering plant.
However, ferns do not produce flowers or seeds. Instead, spores
are formed on the underside of the fronds.
