Inflorescence of Coll. No. 2036, Besseya plantaginea
Described by James (1825) in his Catalogue of Plants, collected between Palmer Lake and Fountain.

V[eronica] plantaginea. N. S.? Flowers spiked, unibracteate. Capsule nearly orbicular, dehiscent at the margin. Radical leaves numerous and large, oval-lanceolate, stiped. Margin crenate. Those of the scape few, sessile, and alternate, Spike long, dense-flowered.

This plant, so unlike in habit and appearance to the American Species of Veronica, seems referable to no other Genus among the Pediculari of Jussieu, to which it is manifestly nearly allied. Habitat on open plains within the Rocky Mountains; flowering in June and July.

Hufford and McMahon (2004) make a strong argument for submerging Besseya back into Synthyris.

A central concern is the paraphyly of Synthyris in the face of continued recognition of Besseya as a coordinate group. We advocate a classification that reflects our knowledge of evolutionary relationships, especially monophyletic groups. Thus, we consider it important that Besseya be classified as part of Synthyris (Hufford and McMahon, 2004).

Full Size ImagePartially weeded patch os smooth brome at the top of the hill.
Full Size ImagePost-weeding photo, not terribly enlightening.  

Weeded a patch of smooth brome on top of the hill.

There was an isolated patch of smooth brome mixed into the remnant mixed-grass prairie on top of the hill. I estimate it to be 1 to 1.5 square meters in size.

Over the course of two days, with about 1 hours of work, I pulled all of it. This resulted in 2 shopping bags of grass to dispose of. Probably weighed about 5 pounds. This material was removed to my residence and disposed of in the yard waste bin.

Generally, the culms snapped off at the ground surface. Though, in about to 1/3 of the stems I removed at least some root material. Occasionally I would get a rhizome to 6-8 cm in length.

I pulled mostly smooth brome, although occasionally I would also pull cheatgrass and alyssum.

I occasionally accidently pulled a native, such as mistaking a stem of scurf pea for a culm of smooth brome. However, overall, I suspect I did more damage to natives with my knees and shoes that by accidently pulling them.

Access to the patch without damaging the native vegetation was difficult. The plants are sometimes hidden in the litter, and sometimes too dense to step anywhere without stepping on a native. I noticed this with the cacti and with Eriogonum effusum.

The remaining native plant vegetation is shown in the list below.

Within the patch of smooth brome there were many small Echinocereus viridiflorus. It is not clear to me whether the small cacti were new seedlings and the smooth brome was acting like a nurse plant, or whether the cacti were small because of competition with the smooth brome.

Will removal of smooth brome simply prepare more habitat for cheatgrass and alyssum?

How quickly will the smooth brome re-assert its dominance in the patch?

How many years of weeding are necessary to completely remove the smooth brome?

Without post-weeding water, will the remaining natives suffer from root disturbance and from sudden exposure?

Should cheatgrass and alyssum be removed at the same time?

When weeding smooth brome around natives, should we be pulling the culms, or digging out the crowns and rhizomes?

Looked for Colutea arborescens along Cressman Gulch.

C. arborescens is native to Europe and North Africa, but it is known on other continents where it is grown as an ornamental and used in landscaping for erosion control. It is also known in the wild as an occasionally weedy escapee from cultivation.

C. arborescens is on the monitor list of noxious weeds for Washington state, but has no special status in Colorado. Friends of Bidwell Park (Chico, California) lists it under the heading of "Plants ranked #1 on park priority list: Highly invasive. Should have immediate management," with the following comments,

Came from 1 plant in 1890s. Control attempted in past, focused eradication program started by FOBP in May, 2003 with about 1M plants removed so far. People spread seeds by "popping" pods as they walk through the park.

C. arborescens has potential to become invasive in New England (Martine, et al., 2008)

Despite the small size of the town, this is a strategic location, lying in a broad mountain pass on the divide between the Yampa River to the north and the Colorado River to the south. As a result, the town is traversed by not only State Highway 131, but also the former Craig branch of the Denver and Rio Grande Western Railroad.
