Inflorescence: panicle, raceme, spike, or flowers solitary in axils, generally open; bracts leaf-like or not
Flower: bisexual, radial or bilateral, sometimes inverted (pedicel twisted 180°; hypanthium generally present, ± fused to ovary; sepals generally 5; corolla radial to 2-lipped, generally fused (tube sometimes split down back), lobes generally 5; stamens 5, free or ± fused (anthers and filaments fused into tube or filaments fused above middle); ovary inferior, sometimes half inferior, chambers 1–3, placentas axile or parietal, ovules many, style generally 1, 2–5-branched

YOU CAN HELP US make sure that our distributional information is correct and current. If you know that a plant occurs in a wild, reproducing state in a Jepson bioregion NOT highlighted on the map, please contact us with that information. Please realize that we cannot incorporate range extensions without access to a voucher specimen, which should (ultimately) be deposited in an herbarium. You can send the pressed, dried collection (with complete locality information indicated) to us (e-mail us for details) or refer us to an accessioned herbarium specimen. Non-occurrence of a plant in an indicated area is difficult to document, but we will especially value your input on those types of possible errors (see automatic conversion of distribution data to maps).
