7	Poison Oak (Toxicodendron Diversilobum)	A native, it can assume the form of a shrub or vine.  Both the leaves and stems contain a toxin which can cause severe skin rash in many people, although other animals are immune to its effects.  It has compound leaves made up of three leaflets. Can reach 4-5 feet in height as a shrub, but can also climb trees as a vine.
37	Coast Live Oak (Quercus Agrifolia)	A native evergreen tree, it is not deciduous, which makes it appear "live" year-round.  Its leaves are small, waxy, and spiny, which is a dry-climate adaptation, and the acorns are thin and pointed .  It is quite fire-tolerant and can attain a height of 80 feet.
17	Prickly Pear Cactus (Opuntia Littoralis)	A sprawling, native cactus with flattened, leaf-like, succulent stems. The spines are modified leaves. Arising with the spines are fine, hair-like, barbed bristles, called glochids. Glochids are found on all of the Opuntias (both prickly pears and chollas). Young growth (flower and stem buds), bear small, fleshy, deciduous, true leaves.

3	Western Sycamore (Platanus Racemosa)	A native, deciduous tree, it has hand-shaped leaves with five "fingers".  The bark has splotches of white and brown which make it look as if it's peeling, somewhat resembling a jigsaw puzzle.  Found not far from water, it can reach a height of 90 feet.
9	Agave (Agave Americana)	An introduced shrub with spiky, jagged, bluish-green leaves, it sends up a stalk which grows rapidly and can attain a height of 20 feet.
