Leaves 0 or in basal rosette, simple
Inflorescence: raceme, spike, 1-flowered or scapose
Flower bisexual; calyx 2-lipped, generally 45-lobed; corolla 2-lipped, 5-lobed, spurred at base, lower lip arched and generally pouched upward, blocking throat; fertile stamens 2, epipetalous; ovary superior, chamber 1, placenta generally free-central; stigma unequally 2-lobed, ± sessile

Annual, perennial herb, generally aquatic
Stem submersed or creeping, uncoiling at tip, sometimes with claw-like appendages, with generally alternate green branch systems ("leaves") of ± linear or thread-like segments; bladders borne on stem or "leaves" trap small organisms when entrance hairs triggered; terminal, overwintering buds dispersed in some species

|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).|
