Leptosiphon aureus (a.k.a. Leptosiphon chrysanthus{{cite web |title=Plants of the World Online |url=https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:60468352-2}}) is a species of flowering plant in the phlox family known by the common name golden linanthus.[https://www.calflora.org/app/taxon?crn=14578 Calflora: Leptosiphon chrysanthus]
Description
Golden linanthus is an annual herb producing a thin, threadlike stem with occasional leaves divided into narrow needlelike lobes. The oppositely arranged leaves are each divided into very narrow bristlelike lobes up to a centimeter long.[https://ucjeps.berkeley.edu/eflora/eflora_display.php?tid=103483 Jepson eFlora: Leptosiphon chrysanthus]
The tip of the stem has an inflorescence of usually a single flower with corolla lobes under a centimeter long. The nominate subspecies generally has bright to golden yellow flowers, while ssp. decorus has white or cream blooms. The bloom period is March to June.
=Subspecies=
The two subspecies overlap in geography but do not occur together.
- Leptosiphon aureus ssp. aureus (Leptosiphon chrysanthus ssp. chrysanthus) — pinyon-juniper woodlands, madrean pine-oak woodlands in Madrean Sky Islands, and desert flats.
- Leptosiphon aureus subsp. decorus (Leptosiphon chrysanthus ssp. decorus) — endemic to the Mojave Desert in California.
Distribution and habitat
The plant is native to the Southwestern United States in Arizona, Nevada, New Mexico, and Southern California; and to northwestern Mexico in Baja California state.[https://npgsweb.ars-grin.gov/gringlobal/taxonomydetail.aspx?id=459779 GRIN-Global Web v 1.9.4.2: Taxonomy of Leptosiphon aureus var. aureus]
It grows in desert flats and desert chaparral of the Mojave Desert and Sonoran Desert; in chaparral and woodlands of the Peninsular Ranges and Transverse Ranges; and in pinyon-juniper woodlands and madrean pine-oak woodlands of Madrean Sky Islands.
