February 2010 Plant of the month by Doreen Smith
Zigadenes of Marin County
dwarf Zigadene near Dillon Beach
photo by Doreen Smith
"The Zigadenes in this area begin to flower this month. The earliest species are of the Zigadenus fremontii group, now likely to be put in a new Family, Melanthiaceae, and called Toxicoscordion fremontii! The following forms are all lumped into the same species.

"On the S-facing slopes of Mt. Burdell there is a fine population of large-flowered plants with yellow anthers. This same form is present in the Marin Headlands along the Bobcat trail and on Ring Mountain .

"On the immediate coast is a dwarf strain that can be seen on the headlands above Drakes Estero, east of the visitor center, near Marconi and at Oceana Marin, near Dillon Beach. This is the one pictured above.

"The most common form in Marin is a tall variety with branching inflorescences and white anthers that's most usual in chaparral openings and especially after fires.

"Also in serpentine chaparral, such as on the Carson Ridge, there is a small-flowered, unbranched form.

"Occasionally a form can be seen in the upper edge of the Pickleweed zone of salt marshes.

"Zigadenus micranthus var. fontanus = Toxicoscordion fontanum, is much later to flower (May) and usually is associated with seasonally-wet serpentine habitats, for example the seeps below Old St. Hilary's chapel, Tiburon and about Rock Spring, Mt. Tamalpais.

Wildflower reports from Marin County
Report (email us) your Marin native plant sightings and photographs
All reports from 2003 to present

February 7 Eva Buxton reports: "On the CNPS hike to Cascade Falls today, we saw California pipevine (Aristolochia californica), a widespread but uncommon plant in Marin. Brad Kelley sent an article reminding me of its pollination by fungus gnats, which are attracted to the flower that emits a foul odor. The gnats enter the "bowl" of the pipe and get trapped for a long enough time to increase the chance of pollination. The flowers form tiny pipes less than a cm before the leaves appear and then continue to grow to a size of 2 - 4 cm. This is unusual in the plant world; the flowers of most plants have reached full size before emerging from the bud."

Trevor February 7 Wendy Dreskin reports: " Junior Botanist Trevor found Indian Warriors at Cascade Canyon on January 28. He also found Sanicula laciniata at Lake Lagunitas on February 4."

February 3 Sharon Salisbury reports "Today at Homestead were Hound's Tongues, Trillium ovatum, hundreds of Fetid-Adder's Tongues, Milkmaids (everywhere). On the firetrail behind the golf course in MV there were Zigadene Liles just about to burst last week...2 weeks ago in the Marin Headlands I saw Wall Flowers, Indian paintbrush, Monkey flowers, California poppies and Foot-steps-to-spring."

January 23 Bob Sills reports:"Today I saw a lone Trillium ovatum in bloom (although the flower was folded up) in Muir Woods. I also saw a few milkmaids..."

January 18 Doreen Smith reports: "Vernon and I did some hiking on the weekend to see early flowers before the forecast rainstorms.
Mt. Burdell lower slopes: the peppercress, little Blennospermas and Star-lily Zigadenes are starting to bloom. There are a few goldfields in the fenced-off area west of the San Carlos Dr. gate.
Blennosperma nana

Sydney and Grace January 16 Wendy Dreskin reports: "St. Rita Junior Botanists Sydney and Grace found and identified the first buttercup on the hill behind their school on January 15. Last year students didn't see the first one until February 1! "

January 14 Faith Brown reports: "Hundreds of Indian Warriors (Pedicularis densiflora) on the Wood Oaks Trail off N. San Pedro Road. Some in full bloom, others not open or just popping up."

Amelia Ryan reports: "More than a dozen Hound's tongue (Cynoglossum grande) were in bloom already at the Tiburon Uplands Preserve on Saturday, January 9th. I also saw a few Indian warriors (Pedicularis densiflora) and a milkmaid (Cardamine californica) in bloom and a death camas in bud. Sadly, I neglected to bring my camera."

Garrya elliptica

photo by Dean Kelch Dean Kelch reports: "Garrya elliptica and Arctostaphylos canescens were in full flower on the trail between Mt Theater and West Point Inn on Mt Tamalpais on Sunday 1/3/10. A. nummularia was flowering along the Matt Davis Trail."

Cardamine californica

Scoliopus bigelovii
photo by George McRae December 21 George McRae & Heidi Rand report: " ...many Brownies (Scoliopus bigelovii) in bloom in Muir Woods along the main trail just short of Cathedral Grove on Friday December 18th. We took a trip to Cascade falls yesterday Dec 20, but saw none. "

Arctostaphylos manzanita

photo by Vernon Smith December 19 Vernon Smith reports: "On David Herlocker's hike today, I saw Common Manzanita (Arctostaphylos manzanita) and California Goldenrod (Solidago californica) in bloom on Big Rock Ridge.
Things seem to be somewhat early."

Castilleja subinclusa ssp. franciscana
photo by Dave Strauss November 8 Dave Strauss reports: "It was surprising to see several plants in bloom in the Marin Headlands today including: Eschscholzia californica, Mimulus aurantiacus, and Castilleja subinclusa ssp. franciscana. I also observed Arctostaphylos sp. in bloom high up along Gold Hill Grade in San Rafael yesterday."

    At its marsh restoration projects the Marin Audubon Society (MAS) has frequent opportunities for volunteers to help both with planting native plants and with controlling invasive non-natives. During the rainy season MAS volunteers have been planting creeping wild rye grass, Leymus triticoides, on uplands along the levees at Bahia in Novato. The planting season is coming to an end soon, but we still have a good supply of Leymus in our plant nursery for transplanting and a large area in which to plant.
    We need many hands to help with planting. Everyone is welcome.
    Tools, water and snacks will be provided. Meet at the end of Topaz Drive near Bolero Court.

New and Revised MARIN FLORA
The new edition of John Thomas Howell's classic 1949 Marin Flora. is co-authored by Wilma Follette, Catherine Best and Frank Almeda, Senior Curator of Botany at the California Academy of Sciences in San Francisco, and is a joint project of the Marin Chapter of the CNPS and the Academy of Sciences. This updated edition has added 416 line drawings to assist in keying species, new well-tested dichotomous keys, and color photos of plant communities in Marin. There are new maps along with satellite images of Marin County. As much as possible has been preserved of Howell's original plant descriptions that have long delighted botanists as well as his insights and poetic observations. Hard and soft cover books will be available for purchase at chapter meetings or you can Order Marin Flora from the Marin Chapter CNPS. Marin Chapter members have contributed many hours of volunteer labor andexpertise; work was carried out at the Academy where plant specimens are retained. Publication was made possible by Tom Howell's generous remembrance of the chapter in his will when he died in 1994.

Calochortus tiburonensis 
 photo by Mary Aline Stevens



Our logo is the Tiburon Mariposa Lily
(Calochortus tiburonensis).
This extremely rare lily can be seen blooming from the end of May through mid-June among the serpentine rocks of Ring Mountain in Marin County, California. In fact, this is the only place in the world it has ever been found growing in the wild. It was first noticed by botanists in 1971 when the small patch of land on which it lives passed from private into public hands. The plant is now in cultivation and can be seen in botanic gardens.

The California Native Plant Society is a non-profit organization of amateurs and professionals united by an interest in the plants of California. Its principal aims are to preserve the native flora and to add to the knowledge of members and the public at large. It seeks to accomplish these goals in a number of ways, including: The work of the Society is carried out primarily by the volunteer efforts of the members of CNPS chapters throughout the state. Money at the State level is provided by the dues of members. Local chapters raise money through plant sales and poster and book sales. The California Native Plant Society has 9,000 members statewide. The Marin Chapter, which was founded in 1973, has approximately 500 members.
