To create an accurate description, I would need specific information about: - Native Status - Bioregional Distributions - Elevation Range - Habitat - Flowering Time - Jepson Description details about stem, leaves, flowers, etc. Without these critical pieces of information, I cannot construct a description that meets the quality standards demonstrated in the examples. Could you provide the missing data for Castilleja ambigua var. heckardii?
