Close-up images of the upper stem and inflorescence of compact phacelia as seen near 7850' on east-facing cliffs at the eastern edge of the Devils Garden (about 150 meters south of the Highline Trail #114) on the northeastern slopes of Mt. Adams.........July 24, 2005. Note the spreading hairs on the leaves and stem as well as the mixture of leaves lacking or having up to two lateral lobes at the base of the blade. The stems are at most 15-20 cm high. Note the numerous, spreading hairs, especially on the coiled inflorescences and the light colored flowers with stamens which jut far beyond the petals.
