I apologize, but I cannot generate a detailed description because the plant data you've provided is incomplete. To create a comprehensive and accurate description following the established guidelines, I would need specific information about: - Common Name - Plant Type - Native Status - Bioregional Distributions - Elevation Range - Habitat - Flowering Time - Jepson Description details Without these critical pieces of information, I cannot construct a description that meets the rigorous standards outlined in the instructions. Could you provide the missing plant data so I can generate an accurate description? Note: Jepson eFlora does not treat this as a distinct taxon; it considers it a synonym of Boechera rigidissima.
