Discussion

Plants of var. collina are diminutive in many respects compared to those of var. sparsiflora.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

In the southern portion of the interior North Coast Ranges of California, plants of var. sparsiflora with corollas 14–20 mm and strongly declined occur on mafic substrates of volcanic origin. V. M. Newsom (1929) treated these plants as var. arvensis.

V. M. Newsom (1929) treated plants of var. sparsiflora with corollas 9–13 mm in the Cascade Ranges of southern Oregon and northern California as var. bruceae. The shape of the corolla of var. bruceae is intermediate to that of the smaller-flowered var. collina with which it is sympatric. These plants are not as tall as those of the Coastal Ranges of California.
