Red Sage - Kochia americana
State Rank Reason (see State Rank above)
The species is at the periphery of its range in Beaverhead County where it is known from one large extant population on BLM and private lands, two historical locations and two other locations that need additional survey work. Agricultural conversion has significantly reduced available habitat. Additional impacts to K. americana from agriculture, grazing and/or invasive weeds are possible.
Red Sage is a perennial subshrub having a woody base and simple or branched, herbaceous stems that are up to 5 dm high. The alternate, fleshy, linear leaves are 5-25 mm long. Foliage is sparsely long-hairy. Small clusters of 2-5 tiny, sessile flowers are borne in the axils of the upper leaves. The 5 hairy calyx lobes are 1-2 mm long, surround the ovary and 5 stamens, and completely cover the 1-seeded fruit. Petals are lacking.
Flowering from June-August.
Some species of Suaeda are also subshrubs with linear, succulent leaves, but their flowers and leaves are glabrous.
