1. U. radiata Small. Stems elongate: leaves dichotomously dissected, copiously 

 bladder-bearing: scapes erect, 6-12 cm. tall, bearing near the middle a single

2. U. foliosa L. Stems 9-30 dm. long: leaves 3-10 cm. long; blades forked, 

 each fork pinnately 4-5-dissected into very fine or capillary segments, the 

 segments fewer when the bladders are more numerous: bladders 2 mm. long 

 or less: scapes erect, 1-3 dm. tall: racemes 10-20-flowered: pedicels 1-2 cm. 

 long, recurving at maturity: calyx becoming 4-5 mm. long: corolla yellow, 

 15-20 mm. broad, the upper lip erect, nearly entire, the lower lip spreading, 

 slightly 3-lobed; spur not appressed, slenderly conic, slightly curved, shorter 

 than the lower lip: capsules few-seeded. — Everglades.— (i?a7i., Cuba, Ant.) 



4. LECTICULA Barnh. Herbs. Stems radiating from the base of the 

 scape, usually submerged. Leaves alternate, usually 3-parted, the segments 

 linear. Scapes 1-flowered, the pedicel continuous with the scape: bract tubu- 

 lar, the free margin truncate, notched: bractlets none. Sepals 2, nearly dis- 

 tinct. Corolla transverse at the summit of the scape, 2-lipped, the palate a 

 mere convexity. 



1. L. resupinata (B. D. Greene) Barnh. Stems short, root-like: leaves scat- 

 tered; blades simple or forked near the base, the segments slender, capillary, 

 often bladder-bearing: scapes erect, 2-10 cm. tall: calyx 1.5-2 mm. long: 

 corolla violet-purple, 8-12 mm. long; spur conic, obtuse, distant from the lower 

 lip. — Everglades. 



5. SETISCAPELLA Barnh. Terrestrial herbs, with short root-like 

 branches from the base of the scape. Leaves delicate, evanescent and rarely 

 seen: blades linear. Bladders minute, 2-horned. Scapes 1-niany-flowered : 

 scales below the lowest pedicel scarious, peltate: bracts scarious, peltate: 

 bractlets none. Sepals 2, nearly distinct, scarious, ribbed. Corolla 2-lipped, 

 the lower lip divergently 3-lobed, with a 2-lobed palate. 



1. S, subulata (L.) Barnh. Scapes rooting in mud, filiform, bronze-colored, 

 3-20 cm. tall: racemes 1-12-flowered: raehis becoming zigzag when well- 

 developed: pedicels ascending, 2-10 mm. long, surpassing the bracts: calyx be- 

 coming 2 mm. long: corolla yellow, 6-12 mm. long, 4-6 mm. broad, the lower 

 lip much larger than the upper one, equally 3-lobed ; spur oblong, appressed, 

 nearly as long as the lower lip. — Everglades and low pinelands. — (Bah., Cuba, 

 Ant.) 



6. STOMOISIA Eaf. Terrestrial herbs. Stems delicate, root-like. Leaves 



delicate, rarely seen : blades linear. Bladders minute, beaked but without 



bristles. Scapes 1-many-flovvered : scales below the lowest pedicel several, 



basally inserted: bracts each accompanied by a pair of bractlets. Sepals 2, 



slightly united. Corolla 2-lipped, the upper lip clawed, the lower consisting 



chiefly of the helmet-shaped, laterally compressed palate. 



Corolla less than 1 cm. broad; spur about G mm. long. 1. 8. juncea. 



Corolla more than 1.5 cm. broad; spur about 12 mm. long. 2. S.cornuta.
