76 On the North American Utricular ice. 



from Michaux ; the U. cornuta he never saw. It is undoubt- 

 edly the U. fibrosa of Elliott, but probably not of Walter, as he 

 could not have overlooked the length of the spur ; it may 

 likewise be the U. bijlora of Vahl. 



4. U. gibba. Leafless, floating, scape naked, 4 to 7-flow- 

 ered ; flowers small, yellow ; upper lip of the corolla emar- 

 ginate, lower subtrilobate, the intermediate lobe subrevolute, 

 crenate ; spur gibbous, incurved, obtuse, most entire ; root re- 

 pent, furnished with utriculi, and producing buds (turiones) 

 like No. 2. Inhabits New-Jersey. U Plate VI. fig. 5. 



5. U.fornicata. Leafless, floating; scape naked, 1 to 2- 

 flowered ; flowers yellow, upper lip of the corolla trilobate, 

 the intermediate lobe arched over the palate, the lateral ones 

 appressed, lower lip entire ; spur incurved, conoidal, obtuse, 

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

 furnished with utriculi. Inhabits from New-York to Georgia.

This is the U. minor of our American botanists, but it has 

 no resemblance to the European plant, except in the smallness 

 of the flowers. The U. minor has either no palate, or a very 

 small one, the corolla is said to have "faux aperta ;" whilst 

 the U.fornicata has a rather large palate: it is likewise the 

 U. gibba of Elliott, as appears from his description, and the 

 particular locality assigned by him ; it may be what Walter 

 intended by the U. pumila. 



6. U. longirostris. Leafless, floating, scape furnished with 

 scales, 1 or 2-flowered ; flowers yellow ; upper lip of the co- 

 rolla subtrilobate, the lateral lobes appressed, lower lip rather 

 entire, spur linearly subulate, ascending, subincurved, emar- 

 ginate, longer than the lower lip of the corolla ; root furnish- 

 ed with utriculi. Inhabits Georgia. Plate VI. fig. 7. 



This species agrees in some respects with Lamarck's U. bi~ 

 flora, but that must have been altogether a larger plant. 



7. U. Integra. Leafless, floating, scape furnished with 

 scales, 1 or 2-flowered ; flowers yellow ; upper lip of the co-
