Collinsia heterophylla var. austromontana (Downy chinese-houses) is a native California herb in the Plantaginaceae family, recognized by hairy leaf undersides and unequal lips diagnostic.

Downy chinese-houses is a California native annual found in the Santa Ana Mountains, San Gabriel Mountains, and Peninsular Ranges in shady places within chaparral and mixed woodland at elevations of 300 to 1,700 meters. Flowering from May to August, this plant produces delicate lavender and white flowers with an upper lip smaller than the lower lip, creating a distinctive two-lipped appearance. Growing with slender stems 10 to 30 centimeters tall, it forms an elegant and airy presence in its woodland habitat. Its leaves are sparsely hairy on the undersides, giving the plant a soft, textured appearance with varying leaf shapes along the stem. The flowers, measuring 10 to 15 millimeters long, create charming clusters that attract pollinators in the dappled light of its woodland home.
