OCTANDRIA. MONOGYNIA. 247 



sile, more than an inch long-, about half a line wide; seeds 

 naked. This species, in every respect but the seed, makes 

 a near approach to Epilohium. 



§ II. Capsules veniricose, angular, mostly pedicellate. 



11. glanca. Leaves broad-oval, very smooth and glaucous. 

 12. fruticosa. Partly villous; leaves iinear-lanceolate, sub- 

 denticula:e, acute; petals ubcordate, as broad as long; calix 

 acuminaie; capsule quadrangular, pubescent, oblong-cla- 

 vate. pedicellate; raceme naked below. Bot' J\Iagaz 332. 

 Stem simple, leaves when held betwixt the light, punctate 

 (throug-h a common lens,) punciures very numerous and 

 linear, similar to those of J^ysimachia giiadrifolia, but co- 

 lourless and diaphanous. 



]S. * ambigua more or less pilose; stem simple; leaves 

 lanceolate, or ovate-lanceolate, acute, subdenticulate, pe- 

 tals obcordate, long-er than broad; points of the calix very 

 short; capsule subsessile, always smooth, oblong, and 4- 

 winged; raceme naked below. Hab. Common around 

 Philadelphia with the preceding; apparently a distinct 

 species. Stem simple, leaves linearly punctate (through a 

 lens,) stem moie slender, flowers smaller and usually of 

 a brigliter yellow. In dry and exposed situations, this 

 species, if such it may be considered, becomes very hairy, 

 in wet places often perfectly smooth. — My attention has 

 "been directed to these discriminations through the polite- 

 ness of professor Barton. 



13. * incana. Stem low, slender, and erect; leaves fiat, 

 hoary and tomentose, very eniire, elliptic-ovate, acute; ra- 

 ceme few-flowered, naked, capsules subsessile, oblong and 

 quadrangular. Had. In dry woods, Maryland. — Dr. W. 

 C. Barton, r. s. in Herb. Barton. Stem 6 or 8 inches high, 

 flowers bright yellow. Allied to ffi. frtisticosa^ /3. ambi-

16. *riparia. Nearly smooth; stem erect and virgateiy 

 branched; leaves linear-lanceolate acute, distantly subden- 

 ticulate, flat and rather thick; capsules spiked, distmctly 

 stipitate, obovate, 8-groovecl, valves dorsally ridged. Hab. 

 on the banks of Cape Fear river, Wilmington, North Car- 

 olina, in sittations subject to inundation; often attacned 

 to drift-wood. Obs. Biennial. Stem about 2 feet high, 

 muck branched above, almost entirely smooth^ except in 

 an early state, branches brown. Root leaves lanceolate, 

 distantly denticulate, as are also those of the stem, smooth 

 and lucid, rather thick; stem leaves attenuated at both 

 extremities, linear-lanceolate, almost imperceptibly and 

 g^andularly denticulate, a little perbescent on the margin, 

 opaque betwixt the light, two to two and a half mches
