12 DIANDRIA. MOXOGYNIA. 



land — and 44 in the tropical regions of America, princi- 

 pally in the West-Indies, Carthagt-na, Cayenne, and Peru. 

 Many of these latter species are highly ornamental. 

 Thus attain we perceive a tropical g-enus almost equally di- 

 vided between India and America. 



19. UTRICULAR! A. Lin. (Bladder-wort.) 



Calix 2-parted, the lower division often einar- 

 ginate, rarely cleft. Corolla scarrely tubulose, 

 irregularly bilabiate, upper lip erect, entire or 

 cniarginate, stamiijiferoiis; lower liwj^ev, entire, 

 o-lobed, or crenate; palate more or less cordate, 

 rather prominent on the inner side, calcarate at 

 the base. Filaments of the stamina incurved; 

 anthers connate. Stigma bilamellate. Capsule 

 globular, I -celled, many-seeded (oj)ening by a 

 lateral foramen?) receptacle of the seed, cen- 

 tral, unconnected. 



An evanescent plant of ponds and stag-nant waters, 

 rooting-, and rarely producing setaceous kaves; or loosely 

 floa'in.y, producing leaves which resemble roots, alternate, 

 demersed, and much divided; beset with numertjus in- 

 flated vesicles; also with proper radical leaves, v/hich are 

 alternate, more rarely opposite or verticillate, entire, or 

 dissected; flowers produced on a scape furnished with a 

 few squamula or scale-like bractes, racemose, or more 

 rarely inclined to be one flowered; the U. minor scarcely 

 produces a spur.f 



f Species, 1. cera^opA^/Z/a, the largest North American species, 

 producing inflated leaves at the base of the scape, dividt-d and 

 capillary branched at their extremities, 6 parted verticil laie; 

 racemes producin,y;6 — 10 flowers, lower iip ofthe corolla wiui 3 

 retuse lobes, the upper entire, spur compressed, deeply emargi- 

 nate, half the length o\ the lower lip. tlowers yellow, larger liian 

 tho&e of U. vulgaris, which they, however, in some measure, 

 resimble. Calix persistent. 



Ic begins to appear in the lower part of Delaware, near Leu-is- 

 town, and C(jntinucs to Florida, being more particularly abun- 

 dant iu he warmer siates. Floating.
