One of the best indicators of seasonal rainfall I've found in the oak woodland and chaparral areas of Southern California in which I run is Elegant Clarkia (Clarkia unguiculata). In a wet year it can grow more than 6 ft. tall. This year it is the shortest I've ever observed -- about 5 inches in this photo taken near Lasky Mesa.

A closer look at the feathery blossoms of the holly-leaved cherry (Prunus ilicifolia) reveal a peculiar flower whose many stamens resemble the tentacles of a sea anemone.

Holly-leaved cherry is a member of the genus Prunus -- the same as apricots, peaches, plums and cherries. As is the case with other species in this genus, the seed and leaves may contain hydrogen cyanide. It produces a small, thin-fleshed fruit favored by coyotes.

The photograph was taken on the slopes of Rivas Canyon near Will Rogers State Historic Park, while doing the route described in the post Will Rogers - Temescal Loop. Once again the weather for this (approximately) 21.5 mile loop was post-card perfect. A Google Earth image of a GPS trace of the route is available in the earlier post.

This photograph of goldfields (Lasthenia spp.) was taken on a run on Lasky Mesa in Upper Las Virgenes Canyon Open Space Preserve almost exactly one year ago. This April I haven't seen any goldfields on Lasky Mesa. The soil is too dry for the seeds to germinate. The drought in Southern California has suppressed or delayed the growth of these, and many other species of wildflowers.

Bush monkeyflower (Mimulus aurantiacus) readily hybridizes, producing a myriad of forms and colors, and some interesting work for botanists. This plant pictured above may be a hybrid of local salmon and scarlet colored forms.

New growth on the chaparral shrub laurel sumac (Malosma laurina) at Sage Ranch Park. The red pigment may function as a sunscreen, protecting sensitive new leaves until they mature, and can cope with full sun.

In mid January there was widespread freeze damage to laurel sumac in the Santa Monica Mountains, and other wildland areas near Los Angeles. Although the plant pictured above was not damaged, many laurel sumac plants in low lying and wind protected areas were.

But frost, fire or drought, laurel sumac is a resilient plant that can weather most hazards. At Sage Ranch, many of the plants damaged in the January freeze have already sprouted new growth.

A Winter bloomer, California prickly phlox (Leptodactylon californicum) likes warm, rocky, southwest facing slopes where it can bask in the afternoon sun. The flowers have a subtle, musty-sweet fragrance that is especially pleasant when encountered on a still evening, in fading twilight, near the end of a run.

Shooting stars are among the first wildflowers to bloom following soaking Winter rains. These appear to be Dodecatheon clevelandii ssp. patulum.

The flowers produce a semitransparent, otherworldly seed capsule that traps moisture. This is an adaptation to an environment that may be cool and damp one day, and then hot and dry just a few days later.

An ant forages among the florets of a wreath plant.

I've run past wreath plants thousands of times in the chaparral of local open space areas. At a glance, the nondescript wiry brown plant isn't very appealing. But, it's one of a few plants you'll see blooming in the chaparral in the Fall, so on a run this last November I took a closer look. This revealed a lavender-tinged composite flower that is anything but mundane. And, as I was to discover, a case of probable mistaken identity, and an example of one of the ways new species occur.
