About Narrow Leaf Collinsia (Collinsia linearis) Collinsia linearis is a species of flowering plant in the plantain family known by the common name narrowleaf blue-eyed Mary. It is native to the coniferous forests of the Klamath Mountains in northern California and southern Oregon. It has also been seen in the Sierra Nevada. It is an annual herb producing an erect stem 10 to 40 centimeters tall with narrow leaves turned under at the edges. The flower cluster is a series of nodes, each bearing 1 to 5 flowers. Each flower arises on a pedicel coated in hairy 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.
