Account of discovery of Sagittaria sanfordii at Nicasio Reservoir by chapter member Todd Plummer
On June 12, 2014, while exploring a damp embankment near the junction of an unnamed inlet stream and Nicasio Reservoir, I discovered a patch of an unfamiliar Sagittaria species.
I counted at least 80 plants. Some were in the vegetative state submerged in the creek; others in bloom were growing on the muddy bank. Some plants featured both male and female flowers. The leaves were lanceolate, not “sagittate” (arrowhead shaped). Growing on stems about 1–2 cm long, the female flowers, roughly 2 cm wide, had white petals and spherical, fuzzy green centers. The male flowers, growing in clusters further out than the female flowers, were white-petaled with yellow stamens. I attempted to key it out in the Marin Flora (Howell et al., 2007) and also checked the Herbaria records at Jepson online, but could not find a match. After consulting with Doreen Smith of the Marin chapter of CNPS and Andrea Williams, Vegetation Ecologist with the MMWD, we determined that these were Sagittaria sanfordii, also known as valley arrowhead or Sanford’s arrowhead. This species is afforded 1B.2 status (rare, threatened, or endangered in California and elsewhere) in the CNPS Inventory of Rare and Endangered Plants. Doreen noted that the species had been reported previously in Santa Venetia near China Camp State Park, but the report was unconfirmed and no specimens were known to have been collected.
After obtaining permission from MMWD, I collected two plants and turned them over to Andrea Williams. She has prepared the specimens and submitted them to the California Academy of Sciences herbarium.

Doreen and Vernon Smith visited Lake Lagunitas and found that even though plants were going to seed, some were still in flower including the following.
Heterotheca sessiliflora ssp. bolanderi (Bolander’s golden-aster), Holocarpha virgata ssp. virgata (wand tarplant), Perideridia gairdneri ssp. gairdneri (Gairdner’s yampah).
They also saw a fine Quercus kelloggii (black oak) with acorns, and coming back along the Fairfax-Bolinas Road, the Stephanomeria virgata ssp. pleurocarpa was in flower.

Sue Mace reports that on Ring Mountain, there are a lot of wildflowers in bloom. The Tiburon Mariposa Lily is abundant on the eastern side of the mountain, a great year for them. Also in bloom (there are a lot to remember this is an incomplete list) seep spring monkey flower, blue eyed grass, phacelia, farewell to spring, tar weed, brodiaeas, buckwheats, California poppies, delphiniums and on the western side narrow-leaved mules-ears, pineapple weed, annual lupines, secund lupines.

Doreen and Vernon Smith report that the wildflowers carpeting the valley floor at Bear Valley, Colusa county, are the best since 2011.
The valley provides a glimpse of what large parts of California used to look like before farming changed the landscape.
On Walker Ridge large numbers of Calochortus amabilis are flowering on the fire-damaged serpentine-soil parts of Wayne’s Knoll.

On a trip to the area of the Point Reyes Lighthouse on Friday, March 7, Doreen and Vernon Smith found that the tiny Minuartia rubella (reddish sandwort) were blooming well. According to Jepson, this unusual plant is normally found above 8000′ in the Sierra Nevada and the Klamath Mountains. So our Marin population is disjunct.
