Ivesia baileyi var. baileyi

Bailey's ivesia

Family: Rosaceae · Type: perennial · Native

Conservation status: CNPS 2B.3

Bailey's ivesia is a rare (CNPS 2B.3) California native perennial found in southern Modoc Plateau and adjacent Sierra Nevada Mountains in volcanic crevices at elevations of 1,700 to 2,200 meters. Flowering from June to July, this plant produces pale yellow flowers in delicate clusters with pedicels 2 to 12 millimeters long. Growing with low, compact stems that spread across rocky terrain, it forms dense mats characteristic of high-elevation mountain environments. Its finely divided leaves create intricate, feather-like patterns across the volcanic substrate. The flower's hypanthium bractlets are approximately equal in length to the sepals, contributing to its distinctive alpine appearance.
