Cost: $15 per adult Gardening with Native Plants in the San Francisco Bay Area Native Plants that Attract Birds Marin Flowers of the month for May by Doreen Smith Jewelflowers, Streptanthus species click on images for larger view "Marin has several jewelflowers of interest growing in Marin. They are in the Mustard family, Brassicaceae, and have the characteristic 4 sepals, 4 petals and 6 anthers but unlike many other spp. in the same plant family the flowers are bilaterally symmetrical. "Our most remarkable species is Streptanthus niger, Tiburon black jewel flower, of the serpentine-soil areas of the Tiburon peninsula. Of course it isn't really black, the flowers just have a very dark calyx. "Other species of the Streptanthus glandulosus group in Marin may have pink, purple, yellow or white flowers. The white-flowered one is blooming now on Azalea Hill but in a reduced size due to the last two dry months . "Streptanthus batrachopus, the Tamalpais jewelflower is usually very small, growing on serpentine- bald sites on the n. side of Mt. Tamalpais and also further n. into the Carson Ridge/San Geronimo Ridge chaparral wilds." Volunteers Needed Native Plant Seed Collection Point Reyes National Seashore is currently seeking volunteers to help with the native plant seed collection during the spring/summer of 2008.

Most colorful among the many species of flowers encountered on the E. side of the ridge were red Franciscan paintbrush, Castilleja subinclusa ssp. franciscana." Doreen Smith reports April 30: "Today was David Herlocker's Soulejule expedition. I participated for only a very short time as I had set myself the job of monitoring rare plants in the area. A discovery there was a patch of little mudwort, Limosella acaulis, in the drying seasonal wet place NE of the dam.The rest of the group I left to hike round the reservoir. They found Pogogyne serpylloides, a tiny mint with a strong pleasant odor. "The reduced population of Delphinium bakeri on the Marshall-Petaluma road is now flowering. "Along the cliffs S. of Tomales, Amsinckia lunaris and Clarkia concinna ssp. raichei are flowering in much the same sites as Arabis blepharophylla. "Near the junction of Chileno Valley Road and the Tomales-Petaluma road, Iris longipetala are abundant on the W. of the road and Hemizonia congesta ssp. congesta (with white flowerheads) is in the grassy field to the E. of the road."

New and Revised MARIN FLORAWe 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. 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. Cover illustration: "Mt.

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: or View more photographs of this lily in its native habitat or Visit the College of Marin's "To See A World Project" to learn more about Ring Mountain The California Native Plant Society is a non-profit organization of amateurs and professionals united by an interest in the plants of California.
