Discussion

Most extant populations of Horkelia cuneata are referable to var. cuneata or intermediates between it and the other two varieties, with the greatest concentrations around Monterey Bay and from Morro Bay to Santa Barbara. At its most distinctive, var. cuneata occurs from Santa Cruz to Los Angeles counties, often sharing habitat with var. sericea though also occurring somewhat more inland, but not as far inland as var. puberula. Although not as endangered as the extremes, unequivocal var. cuneata is far from abundant and shares some of the same threats to its prime coastal habitat.
