Discussion

Collinsia multicolor is known from the Santa Cruz Mountains. The flowers of C. multicolor are similar to those of C. heterophylla, including markings at the base of the banner; C. multicolor lacks the curved basal spurs at the bases of the adaxial filaments, and its banner lobes and wings are notched. In C. multicolor, the adaxial side of the corolla tube is rounded and slightly gibbous, unlike the tube of C. heterophylla, which is saccate basally.
