of our European fpecics liereafter dcfcrrbed. Some leaves 

 are accompanied by an eredl xd^ctmoie Jloiver-Jlalk, from four 

 to eight inches high, bearing from fix to twelve crcft yellow 

 Jloiversy the fi/e and fhapc of U. vulgaris, but with a more 

 pointed neSary, and the fruit is bent downwards as it 

 ripens.

reflexed. Leaves furnifhed with bladders. — Native of the 

 Eaft Indies. Leaves and bladders as in the following, but 

 ihejlowers are fmaller, fix or feven upon eichjlalk ; their 

 fcales and braSeas fimilar to that fpecies.

 Clufter fomewhat corymbofe. Upper lip of the corolla the 

 length of the palate, reflexed at the fides. — Native of ditches 

 and deep (landing waters, throughout Europe, from Lap- 

 land to Greece ; alfo in the weilern parts of New York and 

 Pennfylvania, according to Mr. Purfh ; flowering in July. 

 The trailing or floating perennial roots, or runners, bear al- 

 ternate, repeatedly compound, capillary leaves, furnifhed 

 with minute briftles, and bearing numerous little oval com- 

 prefled curved bladders, open and bt-arded at the tip, each 

 containing a bubble of air, along with a drop of watery 

 fluid. Minute aquatic infefts take up their abode in thefe 

 bladders. Floiver-Jlalks folitary, a foot high, though rifing 

 but a few inches above the furfaceof the water, each bearing 

 a corymbofe clujier of from five to eiglit large handfome yel- 

 lowjloivers, each of whofe partial (talks is fubtended by an 

 elliptical, blunt, purplifh, fcaly braBea, fimilar to what are 

 fcattered down the main (talk. Calyx purplifh ; its lower 

 leaf emarglnate. Palate of the corolla tumid, orange-co- 

 loured, (Iriped, projcdling nearly as far as cither of the 

 lips. 



It feems bell to confider the floating (hoots of this herb, 

 and the fpecies of the fame feftion, which bear alternate, re- 

 peatedly compound, leaves, rather as runners from the root, 

 than rcd\ Jle?ns. At leaft tliis hypothefis is countenanced by 

 many of the plants in the firll, as well as fecond, fcftion.

 — Spur conical. Stalk two or three-flowered. Upper lip 

 of the corolla flat, twice as long as the palate. I.,eaves 

 with deep, forked, flat fegments. Bladders radical Na- 

 tive of lakes and flagnant waters, in Sweden, Germany, 

 and Ireland, flowering in July. The runners feein to ori- 

 ginate from an ovate, fcaly, hairy, tuberous root, or inob, 

 and are thickly clothed with much fmaller, more Ample, 

 leaves than the Lift, whofe fringed fegments are broader and 

 flatter. Thefe leaves fcarcely bear any bladders, the latter 

 being found on other parts of the runners, on branching 

 llalks, and more fparingly. Stali flcmler, bearing but two, 

 or at moll three, _^f/'a'cr.f, fmaller than thofe of the vulgaris, 

 but in like manner ftreakcd with red ; their palate Icfs pro- 

 minent ; upper lip flatter. 



The wooden cut in Lohcl and Gerarde exaftly reprcfents 

 the herbage of this fpecies, with its large hiobs, and no 

 doubt their fynonyms are to be transferred hither. The 

 flowering portions may have been, partly at leaft, delineated 

 from the lad, both being, as it feems, nearly equally com- 



mon on the continent, and having been generally confounded 

 together, even by Linnaeus himfelf. We muft not, how- 

 ever, omit to obferve, that M. Turpin, in his exquifite 

 plates of the Flora Parijienjis, reprefents inobs, or as he 

 perhaps more correftly terms them, buds, in the vulgaris, 

 and even the minor, though of a fmaller fize, in both, than 

 we find them in the intermedia. Thefe appear deftined to 

 produce plants in the following feafon. 



36. U. aujlralis. Southern Bladderwort, or New Hol- 

 land Hooded Milfoil. Brown n. 1 — " Stalk with few 

 flowers. Lips undivided ; the lower twice as broad as long. 

 Spur afcending ; flat in front ; keeled underneath. Leaves 

 bearing bladders." — Obferved by Mr. Brown, about Port 

 Jackfon, New South Wales, as well as in the iflandof Van 

 Diemen. Very nearly related to U. vulgaris. Brown.

 fliort, obtufe, keeled, deflexed. Corolla gaping ; palate 

 nearly flat ; lips undivided. — Native of ditches, on bogs 

 in mod parts of Europe, but not common in England, 

 flowering in July. Mr. Purlh met with it in fwamps and 

 ditches on the " pine-barrens" of New Jerfey, flowering in 

 Auguft. This fpecies is not half the fize of U. vulgaris, 

 with which it agrees in hihh, foliage, though lefs compound, 

 and bladders. The /lali is lefs ftraight, more (lender. 

 Fltwers rather fewer, with a much fhorter and very blunt 

 fpur ; lips fcarcely divided, or notched ; palate fo little ele- 

 vated as not to clofe the mouth. 



3^ U. exoleta. Faded Bladderwort, or Hooded Mil- 

 foil. Brown n. 2 " Stalk with one or two flowers. 



Lower lip undivided ; upper fometimcs half thrce-lobed. 

 Spur afcending, emarginate." — Found by Mr. Brown, near 

 Port Jackfon, New South Wales. It is faid to be clofely 

 related to the lait. 



39. U. fibrofa. Fibrous Bladderwort. Walt. Carol. 

 64. Vahl n. 12. Purfti 11. 4. — Stalk with one or two 

 flowers, almoll capillary. Spur obtufe. Leaves briftle- 

 fliaped In morafles on the pine-barrens of Carolina, flower- 

 ing in July. Stalls purple. Ftoivers orange. Purjh. 

 Vahl terms the leaves, as well as Jlalk, peculiarly flcnder. 

 The former are furnifhed with rouudifli-oblong bladders ; 

 the latter is a finger's length, comprefled, bearing one or 

 two liirgcjlowers. 



Poiret confounds this fpecies with theyj/^fi-a of Michnux ; 

 but as Vahl, who appears to have fecn both, keeps them 

 dillinft, we confide in his opinion. Purfh confiders fetaeea 

 zs ihc fubulata of Linnxus, fee n. 45.

 flowers. Spur inflexed, fomewhat emarginate. Mnuthof 



the corolla clofed Native of flagnant waters, and boggy 



rivulets, in Jamaica, flowering throughout the fummer. 

 Linnxus miilook Browne's plant for his own foliofa, n. 32, 

 whicii is much larger, and very different in other refpeils. 

 The obtufa is rather fmalkr than our minor, with more ca- 

 pillary leaflets, and fmaller bladders- Slali two to four 

 inches high, flender, without fcales, racemofe, bearing from 

 two to four fmall, ycWow Jloitiers, " in beautiful fuccefllon," 

 as Dr. Browne cxpri fTes it. Their upper lip is ovate-, con- 

 vex, undivided ; lower rather fmaller, ovate, its prominent 



heart-
