Plant Quiz Answered; Selaginella eclipes!
Scott is correct. This is Selaginella eclipes. Evidently there is still debate as to whether this species is distinct from S. apoda. I am going with S. eclipes based on the lanceolate leaves of the upper stem surface and their long acuminate tips. I have read that the soil acidity is variable, but FNA does say it is from calcareous habitats.
FNA mentions that there is debate as to the validity of this taxon being a distinct species but then says "It is recognized here at the specific level to highlight the problems within this species complex". Wow! A breath of responsible taxonomy. Too bad they are not consistent in this philosophy.

Spring in San Diego!
Bush sunflower (Encelia californica - Asteraceae) and bush monkeyflower (Diplacus puniceus - Scrophulariaceae) are very common coastal scrub species. I also threw in another weed, Bermuda buttercup (Oxalis pes-caprae - Oxalidaceae).
Moving south down the coast, there was a variety of species in bloom at Torrey Pines State Reserve. The reserve is immediately adjacent to the ocean, but sits up on a bluff. The reserve is named for the Torrey pine (Pinus torreyana) which has an extremely limited distribution. Sand verbena (Abronia umbellata - Nyctaginaceae), bush poppy (Dendomecon rigida - Papaveraceae), Shaw's agave (Agave shawii - Agavaceae), and bush rue (Cneoridium dumosum - Rutaceae) were all in bloom during the first week of February when I was there. Several other species were in bloom when I was there, but I limited the post to species I haven't shared with the group before.
I'll leave you with some really bad pics (luckily, I don't earn my keep taking photographs!). The first is a shot of a faint rainbow over the San Dieguito Lagoon as viewed from the bluffs of Torrey Pines State Reserve. San Dieguito Lagoon is another saltwater/freshwater coastal lagoon that has been preserved (somewhat). The second is the tail of a California grey whale. (Yes, you will need to enlarge the pic.) This was the first time I had ever seen whales in San Diego. Obviously, I didn't see too much of the whale - but exciting nonetheless.
I have some photos from more species in bloom in the chaparral east of the ocean that I will post sometime soon.

I have never seen this winter annual (biennial in the southern parts of its range) become horribly invasive, but it is invasive in some parts of its range. It was brought to the United States in the 1700s and spread rapidly west across the country as a result of the spiraled mature style that attached seeds to the fur and feathers of animals and birds. By the 1890s, Erodium cicutarium had already made it to the Pacific Northwest, where it dominated overgrazed pastures.
This photograph was taken in March 2006.

I don't see the resemblance.

Does That Actor Look Like a Botanist?

I need a little spring!
Behold, the harbinger of spring - Erigenia bulbosa! This photo was taken on March 19, 2005 at Fall Creek Gorge in Attica, Indiana.
Trillium nivale, aptly named snow trillium, as it can sometimes be seen flowering while snow is still on the ground. This photo was taken on March 19, 2005 at Fall Creek Gorge.
The ubiquitous spring beauty, Claytonia virginica. In the depths of winter, even the most common of plants can bring us joy. This photos was taken on April 1, 2006 at Mammoth Cave in Kentucky.
When there isn't much florally happening on the forest floor in early spring, Hepatica acutiloba is at its best. This photo of sharp-lobed hepatica was taken at Dowagiac Woods in southwest Michigan on April 15, 2006.
Upside-down, they do look like a Dutchman's breeches, don't they? I took this photo of Dicentra cucullaria at Bendix Woods in South Bend, Indiana on April 10, 2005.
If you've seen the roots of Dicentra canadensis, you understand why it's commonly referred to as squirrel corn. This photo was taken on April 17, 2005 at Bendix Woods.
In mid-April, marsh marigold lights up forested wetlands and seeps. This photo of Caltha palustris was taken in LaPorte County, Indiana on April 19, 2006.
Bloodroot, Sanguinaria canadensis, is beautiful even prior to anthesis. This photo was taken at Waldhaus in Buchanan, Michigan on March 25, 2007.
