Rare Plant Monitoring with Doreen Smith
Doreen Smith is leading an ongoing mostly week-day rare plant monitoring group for the Marin Chapter CNPS. This will be a low-key effort checking on known and new populations of sensitive species on short hikes and mapping them by GPS. Many, but not all trips will be on Pt. Reyes.
No previous knowledge of rare plants is necessary; we will usually concentrate on only one species at a time.
Prospective new participants who are members of any CNPS Chapter are welcomed but need to
contact Doreen first by e-mail (dlsmith@lvha.net) or telephone (415 479 7888).
Joe Kohn Memorial Scholarship Winner
The Joe Kohn Memorial Scholarship Committee is pleased to announce the winner of the 2013 Graduate Scholarship ($1,000). It was awarded to Jason Mills of CSU, Chico. His project is entitled, “Re-establishing the competitive hierarchy in an invaded California grassland through the process of habitat restoration following the prescribed burn of Centaurea solstitialis” (yellow star thistle).
Marin Plants of the month by Doreen Smith:
Cerastium viride,
spring snow or western field mouse-ear chickweed(!)
Cerastium viride photo by Doreen Smith
"This plant, previously known as Cerastium arvense var. maximum, has recently been recognized as an uncommon coastal species from Northern California into Oregon. It has twice the number of chromosomes and bigger flowers than the more inland native chickweed, Cerastium arvense ssp. strictum.

"Plants are perennial, with almost-succulent opposite, entire, sessile green leaves forming mats which can be covered with the showy 5-petalled white flowers looking almost like a dusting of snow on the vegetation. In Marin fine examples can be seen in spring along the cliffs south of Tomales on Highway 1 and on the Chimney Rock Peninsula, Pt. Reyes National Seashore."
Clarkia purpurea ssp. purpurea, a locally rare species.
Clarkia purpurea ssp. purpurea photo by Doreen Smith "According to Howell's Marin Flora 2 we have three subspecies of Clarkia purpurea, the most uncommon of which is the ssp. purpurea. In a good year the large Godetia-type flowers can be seen along the western part of Alexander Avenue, Sausalito, growing roadside in the cherty soil. They also grow along the fire-road to Kirby Cove near the Golden Gate Bridge overlook. Most years, however, plants are small and few and far between. There are records of this species occurring on Tomales Point, Pt. Reyes National Seashore but I've not ever seen them there."

Mount Tamalpais Bioblitz
The Marin Municipal Water District is pleased to partner with the California Academy of Sciences to conduct the second in a series of bioblitzes on the Mt. Tamalpais Watershed. A “bioblitz” is a focused, citizen science survey that captures the biodiversity of plants in a defined area. Participants will visit distinctive and beautiful sites on the watershed to photograph and collect plants for the Academy’s research collections. Last year, our citizen scientists made nearly 700 written observations, recorded data on over 300 plant species, and collected about 200 specimens.
We are optimistic that 2013 will provide us with another great year of Bioblitzes, but we need your help to make our dreams become a reality. We have been working to select new sites near the Sky Oaks Ranger Station in Fairfax-sites with diverse plant assemblages, interesting weeds, and epic views. We are seeking people who have an interest in botany, photography, and/or data collection.
The following are the dates and times for all scheduled events for the Bioblitz season:
Saturday, March 9th 9:00am-4:00pm
Friday, April 12th 9:00am-4:00pm
Saturday, May 4th 9:00am-4:00pm
Saturday, June 8th 9:00am-4:00pm

Is That Plant Really Native? Genetic Considerations for Conservation, Restoration and Horticulture by Dr. Paul G. da Silva
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.
2012 supplement to Marin Flora 2007

Cover illustration: "Mt. Tamalpais from Corte Madera Creek" by Tom Killion © 2004
California's Wild Gardens showcases the splendid abundance of California's native plants in their natural settings - from foggy rain forests and rolling grasslands to high alpine meadows and parched deserts. The book offers a close-up look at more than one hundred special sites in the state, highlighting their distinctive ecology, the rare and unique plants found in them, and some of their more familiar botanical treasures. With its spectacular color photographs and lively writing by some of California's best biologists and ecologists, California's Wild Gardens is the perfect introduction to the state's remarkable botanical diversity. Like the best travel guides, it will inspire its readers to further explore California's natural heritage. In addition to illuminating California's botanical bounty, this book discusses threats facing the state's flora and describes protection efforts now under way.

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 dedicated to the conservation of California native plants and their natural habitats, and to increasing the understanding, appreciation, and horticultural use of native plants. It seeks to accomplish these goals in a number of ways, through: 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.
