Rocky Mt. Woodsia
Woodsia scopulina ssp. scopulina
The photo above shows a cluster of fronds of
Rocky Mt. Woodsia growing from loose rocks on the Aiken Lava Flow at the Snipes
Mt. Trailhead on the southern slopes of Mt. Adams................May 28, 2005.
The fronds are twice-tapered, meaning they are widest at central frond, tapering
to both ends of the frond.
The photograph above shows a close-up of the
lower surface of one leaflet of Rocky Mt. woodsia. Note the minute glands and
sparse long hairs which are glandless. Photographed on the Aiken Lava Flow at
the Snipes Mt. Trailhead............October 14, 2005.
The photo above shows a close-up of the upper
