Martin and Hutchins 1980
Duration: Perennial Nativity: Native Lifeform: Subshrub General: Perennial with stems 10-40 cm tall, puberulent to glandular-puberulent herbage, sometimes stigose; base becoming woody. Leaves: Alternate, densely leafy along stem, ascending, linear to lanceolate to 5 cm long, 1-8 mm wide, entire, shiny green. Flowers: Solitary in axils, 4 sepals/petals, hypanthium dilated upward, 5-8 mm wide at the summit, tube extending 25-50 mm beyond the ovary; sepals 10-15 mm long, yellowish and blotched with red at anthesis, free tips 1-3 mm long; petals yellow, rhomboidal, 15-20 mm long, turning red on drying; stigma discoid, entire. Fruits: Elongated capsule, 1.5-2 cm, narrowed at base, usually curved. Ecology: Found on dry soils, sometimes on limestone from 4,000-7,000 ft (1219-2134 m); flowers April-September. Notes: In the region there are two subspecies: subsp. pubescens and subsp. fendleri. The latter is found only north of the Mogollon Rim and is told apart by the capsule having appressed hairs or being glandular. The former is found from Arizona to Texas and is distinguished by the capsule having spreading hairs. Ethnobotany: Ssp. fendleri has use as a life medicine for internal bleeding. Etymology: Calylophus is from Greek kalyx for calyx, and lophos, meaning crest, while hartwegii is named for the German plant collector Karl Theodor Hartweg (1812-1871). Synonyms: Calylophus hartwegii var. pubescens, Galpinsia camporum, Galpinsia interior, Oenothera greggii, Oenothera greggii var. lampasana, Oenothera greggii var. pubescens Editor: SBuckley, 2010
