Variety hirsuta is presumed extinct on the San Francisco Peninsula. It is known from a single collection at Point Reyes (Marin County) in 1906.
The type collection of Collinsia hirsuta is unknown and presumed to have been lost in 1906. The depiction of corollas is inconsistent in the illustration accompanying the original description. In the detail of a single corolla, slight reduction of the banner is depicted, but in the habit, there is near equivalence in length between the banner and wings. The original publication states that the description was based on plants collected within the vicinity of the meeting (at the California Academy of Sciences in San Francisco). Most known collections are from western San Francisco; these conform to the variety as described here.
Some treatments have classified plants of var. hirsuta (as treated here) as Collinsia corymbosa (V. M. Newsom 1929, cited as transitional to C. bartsiifolia var. bartsiifolia by E. C. Neese 1993b). The reduction of the corolla banner in var. hirsuta is not extreme like that of C. corymbosa. Plants of the former have vegetative characteristics and the inflorescence structure of C. bartsiifolia var. bartsiifolia.
