To generate a description, I would need the complete botanical data for Erythronium howellii. If you can provide the missing information, I would be happy to create a description following the detailed guidelines you've outlined. Note: Jepson eFlora does not treat this as a distinct taxon; it considers it a synonym of Erythronium citrinum var. citrinum.
