 the Missouri Botanic Garden. 



A duplicate of Rugel's no. 137, an excellent complete speci- 

 men, is also to be found in the Herbarium of the Museum at Paris. 

 The Rugel specimen in the British Museum Collection bears notes 

 to the effect that the plant climbs on shrubs and that it is rare. 



I have named the species in honor of Dr. Swartz, the eminent 

 author of the Flora Indiac Occidentalis. 



As regards the true Rhynchosia Caribaca there is so much mis- 

 understanding that it would be difficult to venture an opinion 

 in regard to its identity. In the Index Kewensis R. Caribaca 

 Auct. Plur. ex Bcnth. Mart. Fl. Bras ij .- part i. 205 Is referred to 

 R. ininhna, some broader-leaved forms of which certainly do re- 

 semble the plate on which R. Caribaca was based. The next ref-

 ad ripamfinm. Orinoci, ex Kunth, Nov. Gen. Am. 6. '123 ' (425) et 

 in Florida occidentali." This latter locality for the plant should 

 refer to R. reflcxa Xutt., then given as synonym, a species which 

 is now rightfully reduced to R. viiniina (L.) DC, so that it is 

 probable that the true R. Caribaca does not occur within the limits 

 of the United States. Quite an extensive search in London and 

 Paris for an authentic specimen of this species met with but scant 

 success. In the Herbarium of the Museum of Paris there is a 

 specimen which probably belongs to A'. Caribaca. It has the fol- 

 lowing inscription : "Rhynchosia Caribaca Willd. Jacq. Ic. A 146." 

 Pinned on the sheet after the fashion of the older herbaria is a 

 small label with this note : " Phaseolus Madrepotanis pubescens,
