Oaks (Genus Quercus)Observer
torrancekleinDescription
This is an oak tree, however I am not sure as to what type of Oak it is. Its leaves are smooth and have a certain sheen to them, and its branches are strong and knotted.
Any help in identifying the tree would be appreciated.

Docks (Genus Rumex)Observer
torrancekleinDescription
This plant appears to be a common sorrel according to all of the descriptions, however the images I found online of a common sorrel appeared only similar to this plant, not identical. It has miniature red bulb-like flowers and thin leaves. The stem is thin but sturdy.

Lettuce, Chicory, Dandelion and Salsify Tribe (Tribe Cichorieae)Observer
torrancekleinDescription
This was easy to spot. The distinct yellow flowers stemming from the weed-like leaves made the dandelion very apparent against the dry brush background. These were not too common in Corona Heights, but I did come across a few on my trek.

Yarrows (Genus Achillea)Observer
torrancekleinDescription
This cluster of flowers was hard to identify because there are many shrubs with similarly thin, green leaves and vibrant explosions of pink flowers. These flowers fade slightly to white, and their bunches are located atop an erect stem.

White Ramping-Fumitory (Fumaria capreolata)Observer
torrancekleinDescription
This plant had white bud-like flowers with deep purple ends. It also had leaves that split into two separate components. It grew in disorganized bunches along the grassy hills that ran along next to the trail in Corona Heights. I had trouble identifying the flower, for there were many other plants that fit my description when I researched my findings online.

Common Ivy (Hedera helix)Observer
torrancekleinDescription
This ivy took over a good portion of the rock walls located next to the trail winding up Corona Heights. It was identifiable by its dark-green color and its five-lobed leaves. It is a vigorous climbing shrub that seems to like rocky perches.

Among the many pines and oaks in Corona Heights I found a few Eucalpytus trees. They are defined by their broad leaves, white and grey bark color, and bark that has a tendency to flake off the tree.

Western Sword Fern (Polystichum munitum)Observer
torrancekleinDescription
This fern was just off the trail, and seemed a little dry (there were some arms that were brown as opposed to green). It was one of the few ferns I observed at Corona Heights; the majority of them were off the trail, just far enough to avoid any good pictures.
I identified this as a Narrowleaf Swordfern by the size and color of its leaves, as well as the shape of the individual leaflets.

Florist's Cineraria (Pericallis × hybrida)Observer
torrancekleinDescription
This flower stood out to me. I wish I could find the name of it but alas I had trouble finding it using an online database. This flower was a soft magenta color with anywhere from 3-5 flowers per stem. It appeared to have sessile leaf connections and capitulum flowers.
