Duration: Annual Nativity: Native Lifeform: Forb/Herb General: Annual herb, 10-40 cm tall, from a slender taproot; stems sparsely branched, usually only branching above the middle; herbage faintly scaberulous towards the base of the plant and glabrous above. Leaves: Alternate, sessile, and appressed-ascending; blade linear, 6-20 mm long and 1 mm wide, with a pointed tip. Flowers: Yellow, located at branch tips, sometimes arranged in cymes (round-topped panicles); sepals 5, lanceolate and awn-tipped, 5-7 mm long, the margins glandular and minutely ciliate; petals 5, obovate, 5-9 mm long, bright yellow to orange-yellow; styles 2-4 mm long. Fruits: Capsules ovoid, 4 mm long, separating at maturity into five 2-seeded segments. Ecology: Found in open dry plains, foothills, and woodlands, from 4,000-9,000 ft (1219-2743 m); flowers May-August. Distribution: MT, NV, and WY, south to TX and n MEX. Notes: The keys to this species are the orangish-yellow 5-petaled flowers; the stems which are sparingly branched and usually only branch above the middle; the styles, which are 2-4 mm long and united, appearing to be one style with several small lobes at the top; and the scabrous lower stems (covered with short, rough hairs; use your hand lens). L. aristatum is similar but the stems are completely hairless and branching throughout, including near the base; and the styles are longer, 5-7 mm long, also united into one stalk as in L. australe. Ethnobotany: Hopi used it to treat stomach disorders; Navajo used it to treat kidney disease. Etymology: Linum comes from linon, the Greek name for flax; australe means southern. Synonyms: None Editor: AHazelton 2017
