narrowleaf blue-eyed Mary

Collinsia linearis is an annual herb growing up to 16 inches (41 centimetres) tall. The inflorescence is a series of nodes, each bearing 1 to 5 flowers. Each flower arises on a pedicel coated in glandular hairs. The corolla of the flower angles sharply from the calyx of sepals. It is white to purple-tinted to deep purple-blue, and sometimes bicolored. There are two upper lobes and three lower lobes, the middle lower lobe forming a pouch. Its chromosome number is n=7. Collinsia linearis grows in open coniferous forests at elevations ranging from 200–2,000 m (660–6,560 ft).
