9. Sabbatia campanulata (L.) Torr. Slender Marsh Pink. Fig. 3344.

 Sabbatia campanulata Torr. Fl. U. S. i : 217. 1824. 



Similar to the preceding species. Stem usually 

 very slender and much branched, i-2 high, the 

 branches alternate. Leaves linear, or linear-lan- 

 ceolate. i'-ii' long, sessile, acute, or the lowest 

 much shorter, obtuse, oblong or oblanceolate, 

 sometimes narrowed into short petioles, the up- 

 permost almost filiform ; flowers pink with a 

 yellow eye, about i' broad, solitary at the ends 

 of the branches and peduncles, mostly 5-parted ; 

 calyx-lobes filiform-linear, equalling the oblong- 

 obovate corolla-segments, or somewhat shorter; 

 style 2-cleft to about the middle; capsule obovoid, 

 about 22" high. 



In salt marshes and along brackish rivers, rarely 

 in fresh-water swamps, Nantucket to Florida and 

 Louisiana. Also on the summits of the southern 

 Alleghanies. Bahamas; Cuba. May-Aug. 



10. Sabbatia dodecandra (L.) B.S.P. Large Marsh Pink. Fig. 3345. 



Chironia dodecandra L. Sp. PI. 190. 1753. 

 Chironia chloroides Michx. Fl. Bor. Am. i : 147. 1803. 

 Sabbatia chloroides Pursh, Fl. Am. Sept. 138. 1814. 

 Sabbatia dodecandra B.S.P. Prel. Cat. N. Y. 36. 1888. 



Stem i-2 high, little branched or simple, terete 

 or nearly so, the branches alternate. Basal leaves 

 spatulate, obtuse, ii'-3' long; stem leaves lanceolate 

 or oblong-lanceolate, acute, the uppermost usually 

 narrowly linear; flowers few, pink, sometimes white, 

 solitary at the ends of the branches or peduncles, 

 iF-22' broad; calyx-lobes narrowly linear, about 

 one-half as long as the 8-12 spatulate-obovate co- 

 rolla-segments ; anthers coiled ; style deeply 2-cleft, 

 its divisions clavate ; capsule globose-oval, 3" high. 



In sandy borders of ponds and along salt marshes, 

 Massachusetts to North Carolina, near the coast. July- 

 Sept. Plants of the Gulf States, previously referred to 

 this species, prove to be distinct. 



3. EUSTOMA Salisb. Parad. Lond. pi 34. 1806. 



Erect usually branched glaucous annual herbs, with opposite sessile or clasping entire 

 leaves. Flowers large, blue, purple or white, long-peduncled, axillary and terminal, solitary 

 or paniculate. Calyx deeply 5-6-cleft, the lobes lanceolate, acuminate, keeled. Corolla broadly 

 campanulate, deeply 5-6-lobed, the lobes oblong or obovate, usually erose-denticulate, convo- 

 lute in the bud. Stamens 5-6, inserted on the throat of the corolla; filaments filiform; 

 anthers oblong, versatile, at length recurved, or remaining nearly straight. Ovary i-celled; 

 style filiform ; stigma 2-lamellate. Capsule oblong or ovoid, 2-valved. Seeds small, numer- 

 ous, foveolate. [Greek, open-mouth, referring to the corolla.] 



Four species, natives of the southern United States, New Mexico and the West Indies, 

 species: Eustoma silenifoHum Salisb.
