General Description: Great Basin Downingia is a glabrous annual with simple or branched stems that can be up to 20 cm tall. The sessile, lance-shaped leaves are 5-20 mm long, and the lower wither early. The stalkless flowers are borne in the axils of the smaller upper leaves, or bracts. The flower is borne on top of the slender ovary, which may appear to be a thickened stalk. The inconspicuous, blue-marked-with-yellow corolla is 4-7 mm long and has a 2-lobed upper lip and a 3-lobed lower lip. The calyx has 5 linear lobes that are 3-8 mm long and as long or longer than the corolla. The stamens are united into a column. The many-seeded capsule is 20-45 mm long and 1-2 mm thick.
Diagnostic Characteristics: The 2-lipped corolla is as long as the calyx and is mounted on the long slender ovary; both this facet and the fruit are distinctive. HOWELLIA AQUATILIS has 2-4 seeds per capsule.
