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.

Erodium cicutarium
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 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.

From the mind of Hackelia virginiana...
I Have Completed Stage One Of Our Plan To Take Over The World
By Bur #318 January 7, 2009 Issue 45•02
Bur #318 reporting: Primary objectives have been met. Ready Parent Organism Beta 51.2-6 for execution of Stage Two.I repeat: Stage One of our plan to systematically seize control of the entire planet is complete.
Stage One, Sequence A: I have successfully detached myself from Parent Organism Beta 51.2-6. Strategic placement of Parent Organism Beta 51.2-6 near the edge of Trail 9 resulted in direct fiber contact, which resulted in coerced stem separation, which resulted in total detachment from Parent Organism.
Stage One, Sequence B: I have successfully attached myself to the host sock. As planned, the 100 percent cotton sock proved suitable for my naturally adhesive hooks. In this regard, our calculations were beyond sound—they were flawless. Prior concerns that wind resistance might prematurely dislodge me from the sock were entirely unfounded. The denim pant leg adjacent to the host sock acted as a protective barrier, holding me firmly in place for the duration of the journey.
Stage One, Sequence C: By my best estimate, I have successfully traveled 3.45 miles from Parent Organism Beta 51.2-6. I now sit at a prime vantage point from which to colonize the surrounding hills and meadows. Contact with foreign soil forthcoming.
Dominion over the earth shall soon be ours.
Ready Parent Organism for further seed deployment. I shall proceed forward to Stage Two: random disbursement of our precious bur alleles across a remote location. The production of new parent organisms will initiate the production of new burs, which will initiate the production of new parent organisms, which will initiate the production of new burs, which will initiate the production of new parent organisms, which will initiate the production of new burs.
Burs #2–3,953: Prepare to ward off potential predators with your coarse, inedible exteriors. Let the jaws of neither rabbit, bird, nor deer stand in the way of our collective destiny. Parent Organism Beta 51.2-6 must be allowed to reproduce. In a matter of centuries, the world's fields, weed patches, river basins, and forests will be inundated with our species, thus awarding us total control over every life form on the planet.
Burs #3,954–6,772: Prepare to continue Parent Organism Beta 51.2-6 growth in the direction of the Trail 9 footpath. If, in the event of my demise, another bur should have to complete the Stage One objective, shifting Parent Organism one and one half inches closer to the footpath would increase the odds of direct fiber contact by 46.6 percent.
A mere 7,869,371 stages remain incomplete. I will now commence with the execution of Stage Two, as planned.
Stage Two, Sequence A: Make direct contact with foreign soil. Determining current location....
Current location unknown. I appear to be submerged underneath a large pile of fabric. No soil is visible. I will now attempt to disengage myself from the host sock in an effort to reach the ground. Disengaging now….
Disengaging.
....
I am unable to disengage. Repeat, unable to disengage. I lack the propulsive anatomical structure required for terrestrial locomotion. Alas, I will have to wait until the cotton fibers on the host sock naturally loosen themselves from my tenacious grip. Stage Two and total domination of the planet await. Assuming wait position. Wait position assumed. I am now waiting. Time rewards the patient bur.
Incoming movement detected. Movement approaching quickly. I shall now analyze the movement….
The movement is hostile. I am now entering defensive posture. Hostile contact is imminent. I shall now scan the area for a possible escape route….
Negative! Escape is impossible! Hostile contact imminent! Assuming hiding position! Position failed! Initiating reinforced grip on cotton! Reinforced grip failed! I am now experiencing forced detachment from the host sock! All is lost! Bur #2: Recommence Stage One, Sequence A! Recommence Stage One, Sequence A!
I have failed you all. May future burs learn from my errors and carry on the sacred goal of world domination. Do not give up hope, friends. Victory will one day be yours. Farewell, fellow burs, and long live the Parent Organism!
Long live the—

Hamamelidaceae
gravel bars and rocky streambeds on the Ozark
Plateau in Arkansas, Missouri, and Oklahoma.
Why its range is so restricted compared to its
cosmopolitan cousin, Hamamelis virginiana
(American witchhazel), is a mystery. Perhaps
the ancient geology of the region holds the answer.
The two can be distinguished from each other
by flowering time and color. H. virginiana
flowers in the fall and has pure yellow flowers
while H. vernalis flowers in the spring (as
"vernalis" means spring) and has yellow flowers
with reddish inner calyxes. The bloom period,
however, can overlap as these were found
blooming during the same weekend (January
10 & 11).
