Could been confused with A. regisimontana, A. pallida, and A. pajaroensis, which are similar in general aspect but geographically separated (reports from Monterey, Santa Clara, and San Mateo counties are one of these species misapplied), or A. andersonii, which occurs within its range and intergrades with it. Reports from Eagle Rock are likely misidentified.

A green-leaved, glabrous form occurs infrequently throughout populations of A. glutinosa, which botanist James A. West believes is a recessive byproduct of A. glutinosa’s hybrid ancestry (A. canescens x A. andersonii). Reproduces only from seed (does not stump-sprout) and requires mineral soil for germination.

After the 2009 Lockheed Fire the isolated population on the Last Chance Ridge side of Scott Creek was spared and contained approximately 250 adult plants (many of them quite old). The extensive population on the upper Schoolhouse Ridge, which encompasses a large, topographically complex area may have contained up to 700 scattered individuals (some diseased, some intact) and numerous seedlings recruited since the fire, despite the dessicating, low-nutrient environment (West 2015).

The 2020 CZU Lightning Complex Fire burned the entire area that supports this species. As of 2021, the current status is unknown. Surveys are required to determine whether plants are reseeding and how many will survive the drought conditions in 2021.
