Amabilis Fir, Cascade Fir, Lovely Fir, Pacific Silver Fir, Silver Fir
Abies amabilis
The photo above shows a small shoot bearing
many needles of Pacific silver fir. The upper leaf is green and bears a central
groove, seen in the photo. The tip of each needle also bears a small notch.
This species at first looks very similar to grand fir, but grand fir has needles
that are two-ranked and spread from the stem (Viewed down the axis of the stem,
the 2 rows of needles look like a narrow X.) while those of Pacific silver fir
are often (sometimes like an X) more clustered on the upperside of the stem
(like a brush) with the needles often pointing more forward as seen in the photo
below. The trick is to look at many of the branches since the needles are variable
on Pacific silver fir! All the photos on this page were taken on the Island
Springs Trail on to the east of Little Mt. Adams at the east side of Mt. Adams........August

The photo above shows one of the branch tips
which helps identify this species. The needles are clustered on the upper side
of the stem like a brush.
In this photo, we can see the two rows of silvery
stomatal blooms and notched needle tips of Pacific silver fir. In this case,
the needles appear two-ranked on the stem like a grand fir, but the previous
photo of a stem from the same plant helps identify this as Pacific silver fir. The needles of Pacific silver fir typically measure up to 3 cm long.
The photo above shows the pitch-covered cone
of Pacific silver fir. The cones of this species measure from 8-15 cm long.

The photo above shows the upper portion of
Pacific silver fir with its erect cones. The upright cones help one identify
similar conifers as true firs, as none of our other native conifers have similarly
oriented cones.
The photo above shows the upper surface of
the needles of Pacific silver fir. Note the notched tips and central groove.
