next to Pl. gentianoides, leaves uncial, fl. white or incarnate in sessile 
heads of 3 to 5, involucre of 4 leaves" (Raf. 1. c. 30-31). The following 
specimens have been examined: Grorata: eastern base of Dick’s 
Ridge, alt. 305 m., Whitfield Co., 27 July 1900, P. Wilson 142 (Br. 
Mus.); woods east of Taylor’s Ridge, alt. 350 m., Whitfield Co., 26 
July 1900, P. Wilson, 134 (Kew); near Pigeon Mt., alt. 595 m., 
Walker Co., 1 Aug. 1900, P. Wilson 172 (Kew); ALABAMA: Blount 
Co., Oct. (fruiting), Rugel (Br. Mus.). There are also two speci- 
mens without locality from Schweinitz in Kew Herbarium, bearing 
an unpublished name indicating the same habitat as that originally 
ascribed by Rafinesque to the species. Gray’s S. Boykinii was based 
on specimens collected by Dr. Boykin in “ middle Georgia." The plant 
has not been collected in Tennessee in recent years, and it is not 
improbable that Rafinesque’s specimens came from Georgia. Harper 
has reported it (Bull. Torr. Club, xxviii. 478 (1901)) from Alabama 
(Pollard & Maxon) and from several localities in northwestern Georgia. 
6. Rafinesque’s genus Pleienta! (l. e. 30 (1836)) included the 
Sabatias with 7-12-merous flowers, and had as “type the-CAl. dode- 
candra L." It is thus strictly synonymous with Sabatia Adans. 
(Fam. ii. 503 (1763)), based on the “Gentiana floribus duodecim 
petalis, foliis distinctis" of Gronovius (Fl. Virg. ed. 1. 29 (1739)), 
which is S. dodecandra (L.) BSP. "The Pl. gentianoides with which 
Rafinesque compared his new species Pl. capitata is evidently Sabatia 
gentianoides Ell., for which together with S. Boykinii (i. e. S. capitata) 
the genus Lapithea Griseb. is maintained by some. This was first 
proposed as a section (Pseudochironia) of Sabatia by Grisebach in 
1839, founded on S. gentianoides, and characterized by * Antherae 
uno cyclo tortae, speciosae! Flores subsessiles, capitati," in opposi- 
tion to the section Eusabbatia, including the other species of the genus, 
with “ Antherae demum recurvae. Flores pedicellati, aut paniculati, 
aut caule dichotomo solitarii." In Grisebach's revision of the family 
in the Prodromus the section was raised to generic rank as Lapithea, 
1''497. PrErENTA Raf. (more added) Sabbatia Ad. non alis. diff. 496, cal. 7-12part. 
stam. 7-12 stylo sepe recto &c. — Although this G. chiefly depends on extra num- 
bers, it is a very natural one, prolific also of Amer. sp. It chiefly differs from CAlora 
by the unequal calix. Type the Chl. dodecandra L. which included 12 blended Sp.
