 Sabbatia campanulata Torr. Fl. U. S. 1 : 217. 1824. 



Similar to the preceding species. Stem usually

 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 

 AUeghanies. Bahamas; Cuba. May-Aug. 



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

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



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

 or nearly so, the branches alternate. Basal leaves 

 spatulate, obtuse, li' 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, 

 li'-2i' broad; calyx-lobes narrowly linear, about 

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

 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-

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