Chylismia claviformis subsp. yumae

Family: Onagraceae · Type: annual · Native

Chylismia claviformis subsp. yumae is a California native annual found in southeastern Imperial County in the Colorado Desert, inhabiting dunes and sandy flats in creosote-bush scrub at elevations below 300 meters. Flowering from February to May, this plant produces bright yellow flowers 4 to 5.5 millimeters long that occasionally fade to reddish tones. Growing with strigose stems that are sometimes glandular-hairy toward the tips, it reaches a low, spreading form typical of desert environments. Its leaves feature a terminal lanceolate leaflet up to 65 millimeters long, with lateral leaflets often reduced or absent. The plant's densely hairy texture and delicate yellow blossoms make it a subtle yet distinctive member of the desert landscape.
