In ponds, Lonisiana I and Arkansas! Juno-Ang. — Strms rxtrnsively 

 creeping and floating ; asrending branches l-'J feet liigli. Leaves very 

 sinootli, veiny ; the petiole about the length of the limb. Pedicels 2 inches 

 or more in length. — This plant is certaiidy the same with the Ea><t Indian 

 and S. American J. repens, to which mimorous synonyms are to be referred. 

 Some of its forms are noticed by Hooker dc Arnott (Bot. misc. 3. p. 312). 

 The petals in our plant are yellow throughout, not at the base only, as is 

 represented in the figure cited above. 



2. J. grandiflora (Midix.) : jjcrennial, mostly iiirsute or villous ; stem 

 creeping at the base, erect ; leaves lanceolate, nearly sessile, acute at each 

 end, the low^er ones spatulate-oblong ; flowers (large) nodding before their 

 expansion, on short ebracleolate or minutely bracleolate ])edicels ; lobes of 

 the calyx 5, lanceolate, very acute, hairy, about half the length of the 

 obovate emarginate jjctals ; stamens 10; ovary about the length of the 

 calyx-lobes, rather shorter than the pedicels. — Michx. ! fl. 1. p. 207 ; Bot. 

 mas. t. 2122 ; Ell. si: 1. p. 480 ; DC. ! jnodr. 3. p. 53 ; Hook, c^ Am. I. c.

In bogs and ditches, S. Carolina! and Georgia! May-Aug. — Stem 

 creeping" extensively, 2-3 feet high, villous when young. Ovary 5-angled. 

 — We iiave not seen the fruit, whicli, according to Elliott, seldom ripens in 

 its native situations. It is naturalized in tlie streams around Montpelier in 

 tJie 9outh of France. 



3. J. occidenfalis (Nutt. ! mss.) : perennial ? pubescent ; stem erect, 

 angled ; leaves lanceolate, acute at each end, sessile or with short petioles ; 

 flowers (rather large) on very short mostly bracteolate pedicels; lobes of the 

 calyx 4, ovate, acute, shorter than tlie obovate emarginate petals ; stamens 

 8; capsules elongated, 4-sided, tlirice the length of the pedicels. 



Margin of jionds, Arkansas, Nutfall ! Texas, Drummond /—We adopt 

 Mr. Nuttall's name for this species, but it will probably prove to be already 

 described ; perhaps it is .T. angustilblia, Lam. We have the same or a 

 nearly allied species from the Sandwich Islands. 



4. J. Icptocarpa (Nutt.) : annual, mostly hirsute; stem erect or ascending; 

 leaves lanceolate, nearly sessile ; flowers (small) on short ebracteolate pedi- 

 cels ; lobes of the calyx usually 6, lanceolate, acuminate, hairy, as long as 

 the petals; stamens 10-12; capsules linear, almost cylindrical, much longer 

 than the pedicels.— iN"M«. / gen. 1. p>. 279; DC. prodr. ^. p. 53; Hook. Sf

 ley ! Florida, Mr. Ware! Dr. Chapman! .Tune-Aug.— Stem simple or 

 sparingly branched, 1-2 feet high. Capsule about li inch or more in length, 

 straight "or a little arcuate, at length almost glabrous. 



/_-5. J. decurrens (DC.) : perennial? glabrous; stem erect, branching, winged 

 /^ the decurrent leaves ; branches slender ; leaves lanceolate, acute, closely 

 sessile; flowers almost sessile; lobes of the calyx 4, ovate-lanceolate, acute, 

 about the length of the obovate petals, shorter than the capsule; stamens 8; 

 capsules subclavate-oblong, 4-sided, with the angles slightly winged, twice 

 or thrice the length of the' pedicels. — DC! jrrodr. 3. p. 56. J. erecta, Ab-
