 When I first read the field notes of Annie Alexander and Louise Kellogg, I was fascinated by the descriptions they wrote about the places they went and the plants and animals they found there. By publishing my field notes on the Internet I hope to follow a little bit in their tradition.

Rush Creek, Mono County, California. On the bank of Rush Creek, 3.2 mi. downstream from US Highway 395, and 1.1 mi. upstream from Test Station Road. 37.9333N, 119.0667W. WGS 1984. Elev. 1975 m. Perennial from fibrous roots and rhizomes.

Coll. No. 724, 1 Sep 2010, Characters observed while keying this collection: Perennial from fibrous roots and rhizomes, not thistle-like; generally > 4 dm tall (observed 3.5-4.5 dm); Stem pubesence uniform and sparse; Leaves basal withered at flowering, altho' formerly larger than cauline leaves, without spinulose tip; Peduncle not glandular; Involucre not glandular; Receptacle naked; Phyllaries in multiple series, could be >3; Outer phyllaries not chartaceous (paper-like) but could have scarious margins to half their length, elongate green area at tip, tip acuminate; Flowers not all ligulate; Ray flowers conspicuous, color violet or purple; Disk flowers style branches not tipped with tufted yellow hairs; Achenes with pappus of hairs.

Originally guessed to be Erigeron philadelphicus, but in Taylor's (2010) key, phyllaries in multiple series leds one away from Erigeron. Then I got lost in Symphyotrichum over the question of what basal leaves "present at flowering" means relative to "withered." This led me into S. lanceolatum. With the help of John Strother, I came to see that even though the basal leaves were withered, they were clearly formerly larger than the cauline leaves. This put me on a different path leading, eventually, to S. Spathulatum.

September 7, 2010

So the next day, we began packing our things and we locked up the house and drove home. What was it like being back in the Bay Area? Well, its certainly noisy here, and there are lots of people, and lots of traffic. I especially notice the gasoline-powered garden equipment, the airplanes, and the BART trains early in the morning. The things I miss are: the view out the window, the birds in the morning, the quiet, and the Milky Way.
