Fruit of Coll. No. 2031, Lomatium orientale

Scanned 14 July 2019.

This is described as having 3-4 oil tubes between the ridges. Those oil tubes are certainly visible; then are the slightly darker linear stripes. I assume the “ridges” are at the very edge of the fruit. If so, what are the slightly lighter structures between the ridges called?

In my garden in Alameda, California.

        images/3252-60.jpg

Pipevine Swallowtail (Battus philenor) in my Alameda, California garden.

In the summer of 1999, I noticed two butterfly larvae on the California Pipevine (Aristolochia californica) in my backyard. They each were black with yellow spots. I suspected that they could be larvae of the Pipevine Swallowtail, but they were gone before I could confirm my identification. Then on May 25, 2000, my wife found this butterfly on the Pipevine. It appears to have just hatched out. After several hours it flew away.

Several days later we watched as a Pipevine Butterfly (the same one?) layed seven eggs in two spots on our Pipevine.

Mound Cactus (Echinocereus triglochidiatus).

Sometimes also called Claret Cup Cactus, grows in the rocks in the canyons along Wild Horse Canyon Road. My impression is that the species is more common on the Precambrian schist and gneiss, but I have no data to support that conclusion. Occasionally the species can be found on alluvial soils.

Fragrant Snowberry at Lobo Point.

These photographs, taken May 25, 2001, show the habitat of Fragrant Snowberry (Symphoricarpos longiflorus) at Lobo Point. The plant is the meter-high shrub growing around the Pinyon Pine in the approximate center of the photograph. To date, this is the only location at which I have found this species.

A search of University and Jepson Herbaria at UC Berkeley showed specimens collected by Mary Beal in Fountain Canyon, Providence Mountains, Annie Alexander and Louise Kellogg in Caruthers Canyon, and Carl Wolf in Keystone Canyon.

The stand has very little single leaf pinyon, and the Utah juniper trees are very large and have the appearance of very old trees. The stand is growing on wind-eroded volcanic tephra sand with little understory herbaceous vegetation, which may contribute to making the location a fire safe site (Barbour, et al., 2007)."

At first, I thought a Carex. However, it certainly looks like an annual. So it could be Cyperus.

Of the three characters that distinguish subsp. cathcartiana from subsp. oregana, two, spore size and adaxial epidermal cell size, require measuring in units of µm, something outside the usual abilities of the field botanist. The third character, regarding the cells on pinnule margins being irregular in shape making the margins appear ragged, can be seen with a good microscope.
