“…Although numerous potential pollinators are available and the flowers are highly fertile, seedlings are not commonly seen in nature. This is probably due to the harsh environment in which Tetradymia is usually found (Strother 1974). However, we recently observed many young plants growing in a burned-over area near Wallsburg, Wasatch Co.,…”

“…Other common names include spineless horsebrush and black sage. This species begins flowering about mid-June in the northern part of its range (southern British Columbia and northeastern Washington) and progresses southward to San Bernardino County, California, and northern Arizona where it blooms in late July or early August (Strother 1974).…”

Shrubs of the sunflower family are among the most common and important plants of the Intermountain area. In many valley, foothill, and mountain locations, composite shrubs, especially the sagebrushes and rabbitbrushes, provide the principal vegetation. These shrubs are invaluable as ground cover on natural and disturbed landscapes, as forage for wild and domestic herbivores, and as habitat for smaller creatures. The authors discuss and review vegetative, floral, and reproductive characteristics, hybridization, distribution and habitat, use, and division into subspecies entries for important Intermountain species. The following genera are covered:

“…This character receives its most severe test in the genera Psathyrotes and Psathyrotopsis. These two genera share a strikingly distinctive pappus form, and they have been treated as parts of a single genus in the monograph by Strother and Pilz (1975), but they recognized cytological, geographical, and some structural differences between the two elements. The two genera were listed separately by Nordenstam (1977).…”

“…Ornduff et al also suggest transfer of Crocidium, Dimeresia, Haploesthes, Psathyrotes, and "perhaps" the subtribe Liabinae out of Senecioneae, but the recipient tribe or tribes for these groups is not designated by these authors. However, Skvarla and Turner ( 1966b) place Crocidium, along with Blennosperma, in Senecioneae, and Strother and Pilz ( 1975) place Psathyrotes, which they claim is closely related to Peucephyllum, in Senecioneae. I included Peucephyllum in my ( 1962) study of woods of Senecioneae.…”
