On the North American Utricularicc. 77 



rolla subtrilobate, the lateral lobes subinvolute ; lower lip en- 

 tire ; spur conoidal flattened (eonoidco-complanatum) obtuse, 

 most entire, nearly equalling- the lower lip ; root furnished 

 with utriculi. Inhabits Georgia, particularly on Ogeechee 

 river. Plate VI. fig. 8. 



Mr. Elliott's U. bipartita is no way different from this spe- 

 cies : he described from a dried specimen, and therefore could 

 not be correct. It would be difficult, amongst any considera- 

 ble number of the U. Integra, to find them all with the lower 

 lip of the calyx undivided. A too rapid evolution, or a luxu- 

 riant growth of the corolla above the calyx, will in many in- 

 stances irregularly rupture this last, especially where it hap- 

 pens to be thin and delicate in its structure ; and there is no 

 doubt that to one of these causes we must attribute the exist- 

 ence of the so called U. bipartita. 



8. U. purpurea. Leafless, floating, scape naked, 2 to 3- 

 flowered ; flowers purple ; upper lip of the corolla, truncate 

 emarginate, lower lip three-lobed, the lateral lobes saccate ; 

 palate small ; spur conoidal flattened (conoideo-complanatum) 

 entire, appressed to the lower lip of the corolla; root repent, 

 branching, branches 4 or 5-verticillate, radicles furnished 

 with utriculi. Inhabits from New-Jersey to Florida. U Plate 

 VI. fig. 9, 



This species has been quoted as having been called by me 

 U. saccata. I am the last man in the world to give into the 

 fashionable foppery of changing the names already bestowed 

 upon plants, and deny ever authorizing any one to say thai 

 this was different from the U. purpurea of authors. 



0. U. per sonata. Leafless, radicant, scape furnished with 

 small scales, many-flowered ; flowers racemed, yellow ; upper 

 lip of the corolla emarginate, reclinate ; lower small, entire, 

 obtuse with a point ; palate very large, very prominent ; spur 

 linear-subulate, rather acute, as it were depending ; root small, 

 nuked. Inhabits in bogs from New-England to Florida, very 

 much resembles an Antirrhinum. ^ Plate VI. fig. 10,
