CACTUS FAMILY
Coastal Cholla, Opuntia prolifera, CACTUS FAMILY: The joints of the cholla detach easily, some falling to the ground. Snails snuggle in the cholla. They would either be the native Helminthoglypta tudiculata or the nonnative milk snail (Otala lactea).

Coastal Prickly Pear, Opuntia littoralis, CACTUS FAMILY: The pads (Sp. nopales) and the fruit (Sp. tunas) with the spines and skin removed are eaten by some people. It is not necessarily the large spines you need to worry about but the tiny bristle-like ones. They break off in bunches from the base of the larger spines and will cling to and irritate your skin. White cochineal scale insects (Dactylopius) gather in colonies on the cactus; a red dye can be made from them (Clarke 141).

Doveweed (aka Turkey Mullein), Eremocarpus setigerus, SPURGE FAMILY: This poisonous plant was used by indigenous peoples to capture fish by throwing segments into the water to stun them (Dale, 107). However, the seeds are eaten by mourning doves without harm to those birds (Bryant, "Doveweed [Turkey Mullein]").
