Sphaeralcea gierischii Atwood & Welsh. This species was first named in 2002. It is a wispy plant, easily overlooked, sometime hard to see even when in flower, difficult to photograph. The mostly glabrous plants are roughly 70 cm tall, leaves to 3 cm long, to 0.5 cm wide, 3-5 parted, deeply divided, lateral lobes usually entire or only shallowly divided, stems reddish purple at base, growing on mainly flattened very gravelly benches and their slopes, biologic crusts sometimes present, primary associated species were scattered Ericameria, Atriplex, Lycium andersonii, Hymenoclea salsola, Hilaria jamesii, Larrea tridentata, and the invasive exotic Bromus rubens. In this picture you can also see a native Eriogonum inflatum combating weeds.The species was first added to the Utah Rare Plant Guide in late 2003 and became a federal candidate for listing under the Endangered Species Act in 2008. On August 17, 2012 it was proposed for listing (with a comment period that ended today, October 16, 2012 and hence my finally posting a few of these at this time).This Arizona Strip endemic plant species has an incredibly restricted range along the UT-AZ border, mainly on the Arizona side where it is highly threatened by gypsum mining, and with only one population in Utah. Its total occupied habitat is under 500 acres over an area that is perhaps 10 miles by 5 miles at most, and with less than 1% of the occupied habitat occurring in Utah. Believed to be all or mostly restricted to the Harrisburg Member of the Kaibab Formation. So to say this is obscurely known from Utah is an understatement.April 30, 2005, Virgin River drainage, Washington County, Utah, at approx. 2,475 ft. elev.

Tentative ID is Sphaeralcea munroana var. subrhomboidea. The basis for this is the shallowly but distinctly 3-lobed leaves, although not as clear whether these are reaching halfway to the base; if not then this could be S. munroana var. munroana, but based on other pictures and illustrations of S. munroana var. munroana these leaves do appear to be more evidently 3-lobed. The coarsely/irregular margins would also tend to indicate that this belongs with S. munroana.Distribution for "var. subrhomboidea" includes Oquirrh Mtns just to the south of this location, and the foothills of the Wasatch Mtns. in northern Utah and into adjacent Idaho. Some taxonomists do not separately recognize this var. (or subspecies by some) but just lump it into S. munroana.Another possibility is Sphaeralcea grossulariifolia however it has much more deeply divided leaves as does S. coccinea which also grows in the area.October 16, 1982, Stansbury Island (which is actually a peninsula), Great Salt Lake, Tooele Co., Utah. Elevation approx. 4,250 ft. With cheatgrass.Reference:Holmgren, N.H., P.K. Holmgren and A. Cronquist. 2005. Intermountain flora: Vascular plants of the Intermountain West, U.S.A.
