Synthyris reniformis

Synthyris reniformis (snow queen) is in the Scrophulariaceae family. Leaves are prostrate and covered with fine hairs. If unfamiliar with this species, the first genus that may come to mind is Heuchera. Leaves are shallowly lobed and have toothed margins. Inflorescences are in terminal racemes and are characteristically tubular in shape, violet to blue in color. Hitchcock describes the flower for the genus as campanulate to subrotate (defined below) and unequally four-lobed. Blooms occur in early spring. Leaf shape easily distinguishes this species from others in the genus.

campanulate = bell-shaped
subrotate = almost disc-shaped; flat and circular, as a sympetalous corolla with widely spreading lobes and little or no tube
sympetalous = with the petals united, at least near the base

Scrophulariaceae (figwort) family characteristics include: flowers are bisexual and mostly irregular, 4 or 5 sepals at least partially united, 4 or 5 petals united into a tube usually 2-lipped with 2 lobes above and 3 lobes below, usually four stamens in 2 pairs but a fifth stamen may be present in some species, ovary has a superior position and consists of 2 united carpels (Elpel).
