Mesa horkelia

Family: Rosaceae · Type: perennial · Native

Conservation status: CNPS 1B.1

Mesa horkelia is a rare (CNPS 1B.1) California native perennial found in southern Coastal Ranges, coastal southern California, and Peninsular Ranges, especially on the foothill edge of the Los Angeles Basin, in dry, sandy coastal chaparral at elevations of 70 to 870 meters. Flowering from March to July, this plant produces white flowers in open, delicate clusters with individual flower stems 5 to 30 millimeters long. Growing with sparse, mostly glandular hairs and slender stems, it forms a low, spreading habit characteristic of coastal chaparral environments. Its leaves are compound with small leaflets, typical of the Horkelia genus, creating a fine-textured, delicate green foliage. The flower's hypanthium features an inner rim that is nearly glabrous, with stamens having distinctive filament bases 0.5 to 2 millimeters wide.
