Leptosiphon aureus (a.k.a. Leptosiphon chrysanthus[1]) is a species of flowering plant in the phlox family known by the common name golden linanthus.[2]

Description

[edit]

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.[3]

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

[edit]

The two subspecies overlap in geography but do not occur together.[3]

Distribution and habitat

[edit]

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.[4]

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.[2]
