Annual, perennial herb, shrubs, generally bristly or sharply hairy
Stem prostrate to erect
Leaves cauline, often with basal rosette, generally simple, alternate; lower sometimes opposite, entire
Inflorescence: cyme, generally elongate, panicle-, raceme- or spike-like, coiled in flower, generally uncoiled in fruit or flowers 12 per axil
Flowers generally bisexual, generally radial; sepals 5, free or fused in lower half; corolla 5-lobed, generally salverform, top of tube generally appendaged, appendages 5, alternating with stamens, sometimes arching over tube; stamens 5, epipetalous; ovary superior, generally 4-lobed, style generally entire

| 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). |
