Discussion | Clematis lasiantha is common in the Coast Ranges and the foothills of the Sierra Nevada of California. The Shasta used pounded stems or chewed or burned roots of Clematis lasiantha medicinally in the treatment of colds (D. E. Moerman 1986).

The long peduncles (10-30 cm) elevating the flowers well above the leaves are unique to Clematis baldwinii among the simple-leaved species of Clematis subg. Viorna in the flora. Broad-leaved, large-flowered plants have been segregated as C. baldwinii var. latiuscula, but many intermediates connect the extremes, and flower size is not well correlated with leaf shape. As noted by C. S. Keener (1975), leaf shape appears to be uncorrelated with distribution; collections from a single population often include broad- and narrow-leaved plants.
