Utricularia inflata Walt. Fl. Car. 64. 1788. 



U. ceratophylla Michx. Fl. Bor. Am. 1: 12. 1803. 



Stems long, floating horizontally beneath the sur- 

 face of the water. Leaves alternate, 10-12-dichoto- 

 mous, usually more than 2' long, bladder-bearing ; 

 scape 4-12-flowered, with a whorl of 4-<j inflated 

 floats, above the floats 5'-i2' high; floats 2'-3*' long, 

 lobed and dissected from near the middle; pedicels 

 8"-i6" long; corolla io"-i2" long, the upper lip 

 subtriangular. undulate, often emarginate, the lower 

 lip a little longer and much broader, undulate, faintly 

 3-lobed, with a prominent 2-lobed palate ; spur conic, 

 toothed, appressed to and about half the length of 

 the lower lip. 



In ponds, Delaware to Florida, near the coast. May. 



4. LECTICULA Barnhart. 



Herbs, with horizontal usually submerged leafy stems. Leaves alternate, 3-parted from 

 the very base, the middle lobe erect and linear, the lateral lobes capillary and root-like, bladder- 

 bearing ; bladders slightly beaked, but without bristles. Inflorescence strictly i-flowered, the 

 pedicel continuous with the scape, its point of origin marked by the solitary bract, appearing 

 like a scale above the middle of the scape; true scales none; bract basally inserted, amplexi- 

 caul and tubular, the free margin truncate, more or less deeply 2-notched, without bractlets. 

 Calyx 2-parted, the lobes concave, herbaceous, appressed to the mature capsule. Corolla 

 very strongly 2-lipped, the palate a mere convexity at the base of the lower lip. Anthers not 

 lobed. Capsule many-seeded. [Latin, a couch, from the transverse position of the corolla.] 



Two species, the following, and another, in tropical South America. Type species : Utricu- 

 laria resupinata B. D. Greene.

Scape and pedicel slender. I '-4' high, becoming 

 much elongated. 4-6' high in fruit, the bract 

 i"-l" long. Flower half-reversed so as to rest 

 transversely upon the summit of the pedicel; 

 calyx-lobes subequal, about 1" long; corolla 

 purple, 4"-6" long, the upper lip narrowly oblong- 

 spatulate, the lower spreading, entire ; spur conic- 

 cylindric, obtuse, the tip distant from the lower 

 lip and bent upward; capsule globose, 1V-2" in 

 diameter. 



Margins of ponds and lakes, New Brunswick to 

 western Ontario and Pennsylvania, and South Caro- 

 lina to Florida. Rare and local. July-Aug. 



5. SETISCAPELLA Barnhart. 



Terrestrial herbs, with short root-like branches from the base of the scape. Leaves deli- 

 cate, some basal, erect, with linear blades, usually evanescent and rarely seen, others root-like, 

 borne on the root-like branches, and bladder-bearing ; bladders minute, 2-horned at the apex. 

 Inflorescence racemose, the raceme sometimes reduced to a single flower, when several- 

 flowered usually becoming zig-zag above at maturity ; scales on the lower portion of the 

 scape several, scarious, peltate; pedicels from the axils of scarious peltate bracts, without 

 bractlets. Calyx 2-parted, the lobes scarious, strongly longitudinally ribbed, spreading under 

 or clasping the base of the mature capsule. Corolla strongly 2-lipped, the lower lip commonly
