 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.

North Table Mountain and Park.

From the stream crossing on the City of Golden trail, climbed up the slope to find the spring. It is at the top of the second run, and at the base of a thicket. The spring has been “improved” in two locations. One has a 1 inch black plastic pipe coming out ot a small thicket. Presumably there was a small spring box that is now overgrown. The other improvement is a small metal drum that has been cut open and laid sideways in the watercourse. This probably ensured a small pool of water for wildlife to drink. The drum is now filled with rocks. Above the spring is the head scarp of a large landslide on which the surface is level to sloped back toward the mountain.

From the head scarp I went north to the North Table Mountain Trail, then up the social trail to the top of the mesa. I checked the spoils pile for Astragalus, then returned by way of the Golden Cliffs Trail, stopping to verify the location of Munroa squarrosa.

Other articles: Mono Lake Basin Flora at Deep Cañon  

“In the wrinkled, sage-covered mountains of Nevada near the California border, 30 miles east of Mono Lake, there is a meadow that seems to lie in shadow even on sunny days. Spread across it are hundreds of dark patches, where the soil is mixed with charcoal. These spots lay row upon row, like the ghostly foundations of a dead city. In a sense, that is exactly what they are.

“In 1967, workers with the Forest Service and the Department of Defense stacked 342 piles of juniper and piñon logs in this place — 20 tons of wood per pile, spaced 25 feet apart. Then, at 8 a.m. on Sept. 29, they set fire to them.

“Project Flambeau comprised some two-dozen experiments like this one, meant to simulate an American suburb under nuclear attack … (Fox, 2017)”

ERIGERON COMMIXTUS. With the habit of E. flagellaris, smaller, less stoloniferous, the leaves relatively broader, some entire, others with one or more conspicuous lobes at base of the blade, the whole plant almost hoary with a stiffly hirsute pubescence, this spreading on the leaves and petioles, retrorse on the stems and peduncles : heads, rays, achenes, etc., much as in E. flagellaris.

Canon of the Limpia, mountains of western Texas, 26 April, 1902, S. M. Tracy and F. S. Earle; also collected by the present writer, in the same general region, namely, in the mountains near Silver City, New Mexico, 18 May, 1880, and distributed for E. flagellaris. The species last named has a rather obscure, fine closely appressed hairiness. That of the new one is so extremely different, that were the plants of the size of a Sunflower or Goldenrod, no botanist would confuse them as one species, were the pubescence the only character. I may remark that true E. flagellaris reaches the mountains of even southern New Mexico, where, however, it occurs only in a more elevated biological zone.

We now treat E. commixtus as a synonym of E. tracyi.

ERIGERON TRACYI. Allied to the last but dwarf, only 2 or 3 inches high, densely leafy at base and with no stolons (at least at flowering time): petioles of the spatulate-lanceolate entire leaves shorter than the blade or obsolete; the whole herbage silvery-hoary with a fine dense strigulose pubescence, or this more sparse and spreading on the solitary scapiform peduncle: involucre hispidulous: outer pappus very conspicuous though consisting of only shorter and setiform hairs, the inner of a few very delicate capillary ones.

Davis Mountains, western Texas, Tracy and Earle, 28 April, 1902.

FLAGELLARE (sp. nov.): bienne ? striguloso-puberulum, pumilum; caulibus gracillimis e basi ramosis, floriferis seu primariis simplicibus superne aphyllis monocephalis, sterilibus patentibus flagelliformibus; foliis spathulatis mucronulatis inferioribus in petiolum gracilem attenuatis integris seu radicalibus parce inciso-lobatis, ramealibus parvulis sublinearibus sessilibus; ligulis numerosis gracilibus (albis purpureo tinctis) involucrum hirsutum duplo superantibus; pappo radii et disci conformi duplici, exteriore coroniformi-squamellato conspicuo, interiore e setis sub-20 fragilibus. — Low, moist places, along Santa Fe Creek; May, June. (381.) -- Root slender. Flowering stems 5 to 7 inches high, very slender, few-leaved below the middle, naked and pedunculiform above; the head rather smaller than in the preceding species; the involucre, &c., similar. Lower leaves one to two inches long, including the slender petiole; those of the runner-like sterile branches decreasing to 2 or 3 lines in length. This species should rank next to the foregoing.

The “foregoing” was Erigeron cinereum (sp. nov.), now treated as a synonym of E. tracyi Greene. The head was described as “… as large as those on Bellis perennis …” and the involucre was described as “… hirsutum duplo superantibus …” [… coarse erect or ascending hairs doubly … ??? ]

Torrey & Gray (1841, p. 175) in Flora of North America proposed Erigeron divergens for the small fleabane that was previously illegimately published by Nuttall as E. divaricatuum.
?26. E. divergens: somewhat hoary with a minute hirsute pubescence, diffusely branched from the base; leaves small, entire, acute; the radical somewhat spatulate, narrowed into a short petiole; the cauline scattered, sessile, linear, narrowed at the base; heads (small) mostly solitary terminating the naked branchlets or peduncles; rays very narrow and numerous, twice the length of the hirsute involucre; inner pappus of few (8-12) very slender and deciduous bristles. —Erigeron (Oligotrichium) divaricatuum, Nutt.! in trans. Amer. Phil. Soc. (n. ser.) 7. p. 311, not of Michx.

Rocky Mountains, and plains of the interior of Oregon, Nuttall ! —(? Stems about a foot high, diffuse, ascending, slender, at length much branched. Leaves half an inch to an inch long, 1 to 2 lines wide. mucronate-acute. Heads rather smaller than in E. tenue; the rays (white, Nutt.) nearly similar; the exterior pappus shorter.
