Leptosiphon lemmonii (syn. Linanthus lemmonii) is a species of flowering plant in the phlox family known by the common name Lemmon's linanthus.[1]
Leptosiphon lemmonii is native to the San Bernardino Mountains and the Peninsular Ranges in southern California (U.S.) and northern Baja California (México).[1] It grows below 1900m (6,200feet), in dry inland chaparral, oak woodlands, the Colorado Desert chaparral ecotone, and Yellow pine forest habitats.[2]
Leptosiphon lemmonii is a small, hairy, glandular annual herb producing a thin stem no more than about 15 centimeters tall. The leaves are divided into needle-like linear lobes, each a few millimeters in length.[2]
The inflorescence is an array of a few small flowers accompanied by bracts shaped much like the leaves. Each flower has lobes only 2 or 3 millimeters long, usually white or cream in color darkening to yellow and orange in the throat, sometimes with maroon areas as well. The bloom period is April to June.[2]
