A close-up of the flower of spurred lupine as seen along the School Canyon Trail #468 near the trailhead, Badger Creek Wilderness........May 10, 2015. The spurred calyx as well as the hairs on the upper tip of the wings can be clearly seen.
The photo above shows spurred lupine as seen
at about 3800' on Washington DNR land just south of the Yakama Reservation
on the southeastern side of Mt. Adams..........May 14, 2005.
The photo above shows a close-up of spured lupine as seen at
4100' atop the ridge dividing the Dairy and Cougar Creek drainages. Note the
prominent spur at the upper base of the flower, the banner which rises narrowly
above the wings and the minute hairs at the upper tips of the wing petals, a
key characteristic of this species..........May 29, 2006.
The photos above show spurred lupine as seen in a large clearcut
off a spur road from the end of Rd 6600 on the southeastern side of Mt. Adams.
Photographed near an elevation of 3550' and 3800'..........May 14,
2005. The photos were taken about one-half hour after sunset, so I was not able
to obtain close-ups of the flowers.
The photo above shows spurred lupine in the drier meadows surrounding
the DNR rock quarry at about 4100' abreast a ridge dividing the Dairy Creek
and Cougar Creek drainages at the southeastern corner of Mt. Adams.........May
29, 2005. The photo shows the moderately long and fairly open inflorescence
of this species to good effect.
