Location: Mt. Tamalpais east peak (37.921242, -122.568187) , Mt. Tamalpais serpentine site (37.908863, -122.614644)
Site description: The east peak overlooks the evergreen forest in Mt. tam. Along the trail it is mostly chaparral plants consisting of coyote brush and manzanitas. The trail is a paved loop that has views of the entire bay area. The serpentine site consists of many tolerators and endemics. There are smaller plants and grasses. We saw mostly poppies and some jewel flowers.

The inflorescence is about 1 to 3cm wide, stalked, with an axillary cluster of 6 to 60 pea-like flowers, arranged in a wheel-like shape. The colors range from lavender to purple. There are nine united stamens and one free, and the fruit is a mostly 2-seeded pod. The linear-to-lance oblong or elliptic leaves are green and alternate, and palmately compound.

Creeping snowberry is a perennial plant. The leaves are round and only 5 to 10 millimeters long. The stems form leafy mats that cree[, often near moss. The stems and under-surface of the leaves are covered with brown bristles. Sometimes the leaf margins and fruits have the bristles too. Flowers appear in the spring, and are white, four-parted, on short backward-curving stalks from the leaf axils. The flowers develop into small white berries.

Species 3: Lace Lip, Myriopteris gracillima, Family Pteridaceae
The stems are short-creeping, 4-8 mm in diameter. The leaves are in clusters of 5-25 cm long and 1-2.5 cm broad. The upper surface has dispersed and branched hairs or glabrescent. The underside of brightly colored like the gold back fern.

Narrative: There was a plaque overlooking the laugenitias lake (didn’t know there was another lake!!!) that had my name on it. Apparently I’m some dead guy’s wife. Mt Tam is so huge and it was interesting to see the whole area fom the tallest peak. It kinda scares me because I definitely could get lost if I’m not careful. I wish I could swim in the lakes they look nice.
