Leaves up to 3cm. Some bases cordate. First two leaf surface pics adaxial.
A. sensitiva x regismontana hybrid, growing directly next to A. sensitiva, with many A. regismontana in close proximity.
Burl present. Glabrous (not sticky) fruit with stones fused. Glaucous leaves. Twig and inflorescence with short, non-glandular hairs.
A. glandulosa ssp. gabrielensis with some degree of introgression with A. glauca (to note: only other taxon observed in the vicinity.
Lacking golden glands on the inflorescence and branchlets.
Growing with Arctostaphylos canescens. (white leaved plants)
One of several odd balls along the ridge. Wide, foliaceous inflorescence bracts. All of the Arctostaphylos taxa known from the ridge have +/- scale-like bracts (A. viscida, A. manzanita, A. malloryi). This plant lacks a basal burl, and is in a mixed stand of A. malloryi and A. viscida.
Best guess is A. pungens x glauca hybrid.
The plant lacks a burl (i.e. not A. glandulosa ssp. adamsii), has a congested inflorescence (A. pungens) with strongly recurved inflorescence bracts (A. pungens), glaucous colored foliage (A. glauca), and glabrous branchlets, leaves and inflorescence (A. glauca).
Growing on Miocene sandstone (Zayante).
Diagnostics:
• erect shrub lacking a basal burl
• short AND long glandular hairs on the ovaries
• long, foliaceous inflorescence bracts covered in dense canescent hairs and short glandular hairs
• glaucous leaves covered in short, canescent hairs
• unifacial leaves with stomata on both surfaces
• glandular-hairy fruit
• auriculate leaf bases; some clasping, some with short petioles (less than 4 mm)

This one was pretty odd.
-leaves and new growth covered in canescent hair, both faces
-leaves are strongly lobed, most are totally apetiolate, some have reduced petioles
-immature inflorescence is leafy, open, and canescent
-no root burl
-fruit had unfused stones
Of the local taxa, I'm only really sure that it isn't sensitiva. Perhaps a hybrid?
