California Pipevine (Aristolochia californica)

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.

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.

I thought this Juniper was interesting. The outer branches were all dead from previous years of drought. However, in the 1 1/2 years of normal, or above normal, precipitation, the inside of the Juniper is beginning to sprout and grow new branches.

Photograph taken July 7, 2009.

"There is a remarkable stand of Utah juniper east of Mono Lake near the Nevada border. 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)."

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.

Reveal, Moulton and Schuyler (1999) on Salvia reflexa.

173. Salvia reflexa Hornem.

Salvia reflexa Hornem., Enum. Pl. Hort. Hafn., rev. ed.: 34. 1807.
Salvia trichostemmoides Pursh, Fl. Amer. Sept.: 19. Dec (sero) 1813. - LECTOTYPE: PH-LC 199 (Moulton 156b), designated here! DUPLICATE OF THE LECTOTYPE: PH-LC 198 (Moulton 156a).
Pursh provides a full description of his new species. Meehan (1898: 39) lists only PH-LC 198, apparently unaware of PH-LC 199 from Lambert. He refers the specimen to Salvia lanceolata Willd. (Enum. Pl.: 37. 1809), a later name for S. reflexa. The Lewis type was collected at the Big Bend of the Missouri River in Lyman Co., South Dakota, on 21 Sep 1804 (Moulton, 1987a: 96-99). Epling (in Repert. Spec. Nov. Regni Veg. 60: 103. 1939) did not differentiate among the syntypes when he indicated the type was at PH.

Coll. No. 1383, Linum perenne

Photographed 1 June 2016.

Definitely Linum, maybe L. perenne because the styles are consistently longer than the stamens, which, in Weber & Wittmann (2012), would put us in L. perenne rather than L. lewisii. The key in Ackerfield (2015) does not discriminate between the two taxa based upon characters that can be observed with this collection.

Nyctaginaceae Mirabilis bigelovii

Mirabilis bigelovii in my Salvia dorrii plot.

Photograph taken October 15, 2005.

There is one Mirabilis multiflora that I have been following for a few years. This plant survived, as it is a perennial growing every year from the roots. I noticed, though, that all of the M. multiflora in this area were very much chewed upon. This is unusual. I’m thinking that perhaps the rabbits, or other small mammals, must be very hungry and are forced to eat this plant, even though it may not be very palatable to them.

Coll. No. 682, Calyptridium umbellatum

Scanned 3 Nov 2011. Specimen on left was partially dissected to show whether the infloresence was terminal (C. umbellatum) or axillary (C. monospermum). I can't really see that, but it is clear that there are multiple rosettes (C. umbellatum) rather than a single rosette (C. monospermum).

Lewisia cotyledon in my garden in Alameda.

        images/3526-31.jpg

Cliff Maids (Lewisia cotyledon) happily inhabiting a Strawberry pot.

This used to be one plant, but it caught some kind of rot. So I cut it up in little pieces, but then I didn't know what to do with 16 little pieces of Lewisia. A Strawberry pot was close at hand and pressed into service. These Lewisias seem to really like it. This photograph was taken at the end of August, 2000, when the plants were launching their second major bloom of the Summer.
