327. var. microphyla Raf. (p. 43). 



"Florida." Leaves smaller and pedicels shorter. Obviously 



the plant which I have called Mecardonia acuminata brevifolia 



(in Proc. Acad. Nat. Sci. Phila. 71: 237. 1920), which thus 



-> becomes M. acuminata microphylla (Raf.) Pennell, comb. nov. 



t^ 328. var. cuneata Raf. (p. 44). 



"Carol [ina]. Alab [ama]." A form of the species, 

 i-^ 329. var. angustifolia Raf. (p. 44). 



"Florida." Leaves linear, oblong and pedicels long. A form 

 of the species. 

 t'^ 2,2,0. Ambulia micrantha (Nutt.) Raf. (p. 44). 



"Grat[iola] do. [micrantha] Baldw Florida, disc, by Bald- 

 win." Baldwin's specimen was labeled "Gratiola micrantha," 

 a name published by Nuttall in 1822. Rafinesque clearly 

 described the same species, and his name with Nuttall's must 

 pass into the synonymy of Scoparia dulcis L. 

 i^ 331. Ambulia? psilosa Raf. (p. 44). 



"Grai[iola] 4gona El. his own specimens yet not answering 

 to his description." Rafinesque redescribes Elliott's plant, 

 noting such characteristic features as the obovate or oblong 

 (rather than "lanceolate") leaves and the slightly oblique 

 capsule. With Elliott's Gratiola tetragona 1816, this becomes 

 a synonym of Ilysanthes dubia (L.) Barnhart. 

 (^ 332. Macuillamia rotundifolia (Michx.) Raf. (p. 44). 



" Monniera, and Herpestis do. auct Illinois. 



This G[enus] was established by me in Neogen. 16, year 1825." 

 This earlier publication was not typifiable, no species being 

 cited. But now three are given, the first, by adapted des- 

 cription and also mention Illinois, definitely based upon Monniera 

 rotundifolia Michx., 1803, from that state. In the Proc. Acad. 

 Nat. Sci. Phila. 71:242. 1920. I have used a later generic 

 name Ranapalns Kellogg, 1877, for the group to which this 

 species pertains. This must lapse into synonymy, and R. 

 rotundifolius (Michx.) Pennell give place to Macuillamia ro- 

 tundifolia (Michx.) Raf. 

 K 333. Macuillamia obovata Raf. (p. 44). 



"Virginia in the River Potomac and in Louisiana." Said to 

 be larger than the preceding, to have leaves obovate or elliptic, 

 sessile, and pedicels shorter than the leaves. Evidently a needed 

 redescription of M. rotundifolia (Michx.), and based upon actual
