 wavy, almoft capillary, with onj or two flowers. Spur 

 conical, tumid, bluntifli. Lips of the corolla rounded.— 

 Native of the boggy foil of New Jerfey and Carolina, 

 flowering in July. Flowers yellow. Purjh. This has 

 been erroneoudy arranged among the leaflefs fpecies. The 

 leaflets are briftle-lhaped, accompanied by namerous blaJelers, 

 larger than in the lait, though the Jloiver-Jlalis are fmaller, 

 from two to three inches high, almofl capillary, and fome- 

 what zigzag. Flowers about the fame fize. The Linnxan 

 fpecimens, from Gronovius and Clayton, will not allow 

 us clearly to af certain the fliape of the corolla. The Jptir 

 feems ftraight and prominent, rather (horter than the 

 lips. 



42. U. hydrocarpa. Reflexed-ftalked Bladderwort. 

 Vahl n. 14 — " Stalk thread-lhaped ; partial ftalks alter- 

 nate, remote ; reflexed when in fruit. Leaves briftle- 

 fhaped." — Found by M. Richard in Cayenne. Leaves 

 very (lender, (hort, fcarcely divided, furnifhed with bladders. 

 Stalk the length of the middle finger, with five partial ftalks, 

 half an inch long. Bradeas ovate. Calyx of the fruit 

 ovate, fpreading at the fummit. Corolla purplifh. Capfule 

 globofe, the fize of the calyx, beaked with the Jlyle. 

 Koenig fent from Ceylon, under the name of U. major, 

 what feemed the fame with this in its whole ftrufture, and 

 in which the fpur was conical, obtufe, the length of the 

 upper lip. They could fcarcely be fpecifically diftinguifhed, 

 efpecially as the fpur of the U. hydrocarpa is unknown.

43. U. aurea. Golden Floating Bladderwort. Loureir. 

 Cochinch. 26. Vahl n. 22. — Stalk round, ereft. Flovcers 

 racemofe. Calyx lanceolate. Spur conical, comprelTed. 

 Leaves capillary, with bladders. — Native of flow ftreams 

 in Cochinchina, where this fpecies is known by the 

 name of Cay raong. The runners are very long, flen- 

 der, branched, floating. Leaves very numerous, capillary, 

 green, fubdivided, furnirtied with bladders. Stalk three 

 inches high. Flowers of a golden yellow. Calyx incurved. 

 Corolla deeply divided, its throat (rather palate) convex, 

 emarginate. Loureiro. It is evident that what Loureiro 

 calls Jlem, is what we have in fonie preceding fpecies termed 

 runners, and that his roots are real leaves. Vahl, therefore, 

 might juftly doubt whether he had done right in placing 

 this among the leaflefs fpecies. He appears by fome acci- 

 dent to have tranfpofed the places of aurea and recuriia ;

 marck Illullr. v. I. 50. Vahl n. 16. Purfli n. y. ( U. pu- 

 mila ; Walt. Carol. 64. ) — Stalk moftly two-flowered, 

 thread-fliaped. Spur awl-fliaped, ftraight, about equal to 

 the upper lip. Leaves brillle-fliaped. — On the margins of 

 ponds in Lower Carolina, flowering in July. Flowers 

 fmall, yellow. Purjli. Leaves ftiort, furnifhed with blad- 

 ders. Stalk lender, four inches high, fometimes zigzag, in 

 a dry ftate angular below, naked. Partial /lalks one or two 

 at the top, as long as the nail. BraHea membranous, abrupt, 

 at the bafe of one of the patial ftalks, and on the other to- 

 wards the calyx. Upper lip as long as the nail. Vahl. Wc 



are not without a fufpicion of this being the fame plant 

 as U. gibba, fee n. 41, but have no means of proving 

 it fo.

 — " Stalk about two-flowered Spur obtufe, fliorter than 

 the upper lip." — In fandy wet places, near ponds and rivers, 

 from Canada to Carolina, common, flowering in July and 

 Auguft. Root annual. Flowers fmall, bright yellow. 

 PurJh. This author compared his fpecimens with the origi- 

 nal ones of Gronovius, the only authority in this cafe. No 

 fpecies has given us more trouble than the prefent. Lin- 

 naeus, in Mant. 2. 317, fays, on the authority of Clayton, 

 that the leaves are capillary, and the^owers white. This is 

 tranfcribed by Willdenow, but noticed by no other perfon. 

 Linnaeus, fubfequently to the publication of Sp. PI., laid 

 into his herbarium for U.fubulata, a totally ditlerent plant 

 of Kalm's, which happens to have an awl-fliaped fpur, and 

 is the cornuta of Michaux, Vahl and Purfli. This cannot 

 be the plant of Gronovius. The reader will perceive that, 

 though Vahl has kept fubulata and fetacea diftinft from each 

 other, his fpecific characters are of httle avail, unlefs the 

 latter fpecies be deftitute of leaves, in which cafe it ought 

 to have been placed in the next feftion.

 Carol. 64. Vahl n. 28. Purfli n. 7. — Stalk with two 

 or three flowers. Spur keeled, very fliort. Lips of the 

 corolla rounded. Leaves capillary. — An annual fpecies, 

 found floating in the lakes and ponds of Carolina ; alfo in

 Vahl n. 20 ? (U. fcapo nudo-fquamis alternis vagis fubula- 

 tis ; Linn. Zeyl. 9.) — Stalk ereft, thread-fliaped, with 

 fcattered awl-fliaped fcales. Spike denfe. Calyx-leaves 

 orbicular. Spur the length of the lips. — Native of Ceylon. 

 Examined in Hermann's herbarium, from whence Linnxus 

 defcribed this ipecies, referring to it fynonyms which be- 

 long partly to the following. The flem is without leaves, 

 about flx inches high, terminating in a fliort denfe_^/i.«, of 

 nearly fenile_y?o'u/irrj', whofe colour, according to Hermann, 

 is blue. The orbicular calyx-leaves clearly diftinguifli this 

 from the following, as well as from our graminifolia, n. 19, 

 confounded herewith by Linnjeus, in his own herbarium.

 Exot. Bot. V. 2. I 1 9. t. T19. { Nelipu ; Rheede Hort. Malab. 

 V. 9. 137. t. 70.) — Stalk twining, round, with fcattered 

 acute fcales. Calyx pointed, as long as the corolla. Spur 

 awl-fliaped. Lips rounded. Palate reticulated, two-lobed. 

 Native of inundated rice-grounds, in various parts of the 

 Eaft Indies, which, according to Dr. Buchanan, are co- 

 vered with its moft elegant blue flowers, in December. 

 Root fmall, with whorled fibres, apparently annual. Leaves 

 none. Stalk from nine to twelve inches high, twining round 

 the rice-ftems, in the manner of our fpiralis, n. y, fmooth, 

 cither fimple or divided, bearing many fmall, alternate, 

 clofe-prefled fcales. Clujlers one or more, terminal, lax. 

 Flowers the fize of viplets, and nearly of the fame colour ; 

 their palate clofing the mouth, very prominent, divided, 

 white, reticulated with pale blue veins; thtn partial Jialts 

 tapering at the bafe, each accompanied by three fmall per-
