Alpine Lake October 2008
photo by Doreen Smith Doreen Smith reports October 6: "Vernon and I pre-tripped
the shores of Alpine Lake yesterday. The water level is down
well below normal for the date this year but noteworthy plants
are few. Still I will do the hike more or less as previously planned
on the 12th Oct. but include L. Lagunitas as well because that has
more water in it! The four-leaf clover fern (Marsilea vestita) was
visible but no pillwort-ferns (Pilularia americana)."

Calibrachoa parviflora
photo by Vernon Smith Doreen Smith reports September 25: "More news from our field trips!
Yesterday we found a new native plant species for Marin -
Calibrachoa parviflora (was Petunia parviflora) on the drying
shore of Stafford Lake reservoir, Novato. It was one I
couldn't initially identify to the delight of those present, who in the past
may have suffered from my "know-them-all" deception. "

Astragalus nuttallii
photo by Brad Kelley Doreen Smith reports September 20: " We re-discovered
Astragalus nuttallii (last recorded 1947) on our last
CNPS weekend hike to McClures beach, Pt. Reyes.
Brad Kelley took the picture. Perhaps we found it because
I didn't take along my camera... "

Rare plant of the month by Doreen Smith
" Here are two plants for comparison that can usually be found blooming through November.
One is common the other rare - but they look very similar to each other. As you can see these
California asters have been put in a different genus from the one most of us are used to.
Suisun marsh aster, Symphyotrichum lentum
Symphyotrichum lentum
photo by Doreen Smith "Marin has just one very small known population of
this rare aster - on the SW shores of Chileno Laguna.
It definitely a wetland plant and is more common in the
Suisun marshes, as one might expect. Fine specimens
can be seen south of the first bridge across the slough
that is a little south of Suisun City along Grizzly Island
Road. At the same site there are Symphyotrichum
chilense
and the small-flowered annual S.
divaricatum
for anyone who cares to compare
or key them.

Coastal aster, Symphyotrichum chilense
Symphyotrichum chilense
photo by Doreen Smith "This is the commonest "aster" in Marin and can be found inland as well
as on the immediate coast. The leaves are broader than the above
species and it isn't always growing in wetlands but is often in dry soils
and serpentine areas."

  • Rare Plant Monitoring at PRNS has finished for the year
    San Pablo National Wildlife Refuge
    Audubon California and the US Fish & Wildlife Service seek volunteers to assist with ecological
    restoration and monitoring at the Tubbs Island Enhancement Project in the San Pablo Bay
    National Wildlife Refuge. Volunteers will have opportunities to learn ecological monitoring and
    restoration techniques and species identification. Monitoring will occur on limited access parcels,
    presenting a great opportunity to experience the San Pablo Bay National Wildlife Refuge.

    New and Revised MARIN FLORA
    We are pleased to announce the arrival of
    the long-awaited, revised edition of John
    Thomas Howell's classic 1949 Marin Flora.
    The new edition 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 and expertise; 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.
    Try your hand at identifying the parts of this flower:

    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.
