General Information

Herbs, perennial or annual, terrestrial, epiphytic, or aquatic, without true roots. Stems modified into rhizoids and stolons, rarely developed. Traps on rhizoids, stolons, and/or leaves, small, bladderlike. Leaves alternate or in a basal rosette, simple to many × divided, veins 1-3, unbranched, dichotomously branched, or pinnately branched. Inflorescences racemose or flowers solitary, pedunculate, usually simple, seldom branched, erect to twining, bracteate; bracts and bracteole often present, scalelike, sometimes basisolute (with base extending below point of insertion). Calyx parted from base into 2 equal or unequal lobes, lobes sometimes apically 2-parted. Corolla lower lip larger than upper lip; lower lip entire or 2- or 3(-6)-lobed, spurred, palate variously raised; upper lip entire or 2- or 3-lobed. Anther thecae confluent or distinct. Capsule adaxially loculicidal, both abaxially and adaxially loculicidal, or circumscissile, rarely indehiscent. Seeds few, many, or rarely 1 per capsule, variously appendaged.

    UTRICULARIA L.

    Anuales o perennes, terrestres, epífitas o acuáticas, mayormente estoloníferas, con trampas pequeñas y globosas u ovoides en forma de vescícula. Hojas arrosetadas o alternas, opuestas o verticiladas en los estolones, lineares a orbiculares o divididas en segmentos capilares. Inflorescencias racemosas o raramente de 1 flor; lobos del cáliz 2 (o raramente 4 pero no en Nicaragua); corola amarilla, violeta, rosada o blanca. Fruto una cápsula, dehiscente por valvas o poros, circuncísil o raramente indehiscente.

    Herbs, annual or perennial, aquatic, terrestrial or epiphytic, always of damp places, without true roots or leaves but with stems modified in various ways to function as tubers, rhizoids, stolons, and + leaflike photosynthetic organs, all species bearing small complex bladderlike traps for the capture and digestion of small organisms. Inflorescences pedunculate, racemose, usually simple, brac- teate, sterile bracts (scales) often present on the peduncle and sometimes also on the inflorescence axis; bracts varied, basifixed, medifixed or variously produced below the point of insertion; bracteoles 2 or absent, rarely connate with the bract. Flowers with the calyx 2-lobed, usually accrescent; corolla usually spurred, yel- low or various shades of violet or purple, or white, rarely red, the upper lip en- tire or + 2-lobed, the lower lip entire or 2-5-lobed; stamens usually short, the filaments often winged, the anthers globose or ovoid; ovary ? globose, the ovules 2-many. Capsules globose to ovoid, dehiscing variously by longitudinal slits, dorsiventral or lateral valves or pores, circumscissile or indehiscent; seeds 1-many, variously shaped.
