This annual plant has flowers similar in color to Sticky Snapdragon (Antirrhinum multiflorum), but in some ways are more similar to certain Penstemon. They grow in racemes, or individually in leaf axils. The plant is glandular-hairy, with an erect but weak stem, often clinging to other plants or debris. Leaves are < 5 cm, lanceolate to obovate in shape. The Jepson Manual comments that this plant is abundant every 20–50 years.
