These emergent Horsetails were seen in the riparian zone of Stockhoff Creek, rising out of a stand of Oxalis west of State Highway 1 at Stillwater Cove.
Youngling horsetail plant. One plant had early developed branches.
One still growing with others beginning to sprout up around it.
With the recent rains, horsetails are emerging around Dimond Canyon!
Horsetail is a "living fossil" as it is the only living genus of the entire class Equisetopsida, which for over one hundred million years was much more diverse and dominated the understory of late Paleozoic forests. Some Equisetopsida were large trees reaching to 30 meters tall! Image walking through a forest of these...
Thanks to Josh Sonnenfeld for this great photo!
this has the ragged whorls of arvense, not the tight whorls of telmateia.

Equisetum arvense, the field horsetail or common horsetail, is a herbaceous perennial plant, native throughout the arctic and temperate regions of the northern hemisphere. It has separate sterile non-reproductive and fertile spore-bearing stems, growing from a perennial underground rhizomatous stem system. The fertile stems are produced in early spring and are non-photosynthetic, while the green sterile stems start to grow after the fertile stems have wilted, and persist through the summer until the first autumn frosts.
