  05-Noteworthy Species-Erigeron
An Erigeron L. that appeared to be a variant of the widespread and often weedy
Erigeron strigosus proved to be one of the most characteristic plants of the Ketona Glades, absent only from one of the smallest outcrops, near the western periphery of the glade region.
Erigeron strigosus was considered by Cronquist (1947) to be predominantly apomictic.

 EPA: Federal Register: Endangered and Threatened Wildlife and Plants; Endangered Status for ``Erigeron decumbens'' var. ...
Recent revisions of the Erigeron genus (Strother and Ferlatte 1988, Nesom 1989) treat the plant as a variety, E. decumbens var.
Intermediate specimens of Erigeron from southern Oregon are considered by Strother and Ferlatte (1988) to be robust specimens of E. eatonii var.
However, the potential threat posed by collecting for personal herbarium specimens may be significant, particularly where populations are small, due to the species' rarity and the relative accessibility of roadside populations.

 Leafystem Fleabane (Erigeron subtrinervis)   (Site not responding. Last check: 2007-09-18)
Unlike many Erigerons, this species has numerous leaves on the stem mostly as large as the basal leaves; only the uppermost leaves are noticeably reduced in size.
Some Erigerons are purported to drive away fleas, relieve toothache, and cure various diseases, but I could find no references to any economic values for leafystem fleabane.
The generic name Erigeron stems from the Greek eri, "early" and geron "old man," in reference to early-flowering plants with a hoary appearance.

 ARS | Publication request: Molluscicidal and Antifungal Activity of Erigeron Speciosus Steam Distillate
One approach to disease control is to avoid infestation of catfish by breaking the life cycle of the parasitic trematodes through eradication of the ram's horn snail.
In our search for natural product-based agrochemicals, we found that the steam- distilled oil of Erigeron speciosus is lethal for ram's horn snails and fungicidal against important plant pathogens that cause anthracnose diseases of strawberry.
The bioactive compounds 2Z, 8Z-matricaria methyl ester and its 2E, 8E-geometrical isomer were isolated by bioassay-guided fractionation and chromatographic techniques and identified by 1H NMR spectroscopy.
