 Sept. — Stem 2-4 feet high, wliolly herbaceous. Calyx-segmenLs lanceolate- 

 subulate. Corolla white : vexilluni oblong, scarcely spreading, with a pur- 

 ple spot near the base : wings narrow, scarcely auricled at the base. — This 

 plant has been generally supposed to be the Hedysarum fnitescens of Lin- 

 naeus ; but that species was founded on a jjlant of Clayton's (H. fol. ternatis ; 

 foliolis suliovatis, &c. Gronov. ! Vtrg.), whicli, as our most esteemed friend 

 Dr. B(Hitt first observed, is Linna-us's own H. violaceum, wliile the synonym 

 of Gronovius, adduced under the latter species, belongs to Psoralea raelilo- 

 toides ! But the reference to Mill. diet, in the second edition of the Species 

 Plantarum doubtless relates to the present species. 



Arachis hypogfea (the Pea-nut) was sent in tho late Mr. Drummond's collec- 

 tion, from Covington, Louisiana ; but the specimens were doubtless cultivated. 



Psoralea, Linn, should doubtless be referred to the tribe Hedysarese; as Mr. 

 Benthara has suggested.
