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.

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?
