Yosemite and Tioga Pass Area

It is a real treat to find a jewelflower like this Shieldleaf (Streptanthus tortuosus). The tiny purple, urn-shaped flowers are easily overlooked. The flowers have 4 petals and 4 sepals that alternate to form a cross. By mid-summer the leaves of this mustard plant turn yellow-gold and are more noticeable than the flowers. Long arching seedpods are also beginning to develop. Mustard Family.
