Doubtful or excluded species 



Tephrosia frutescens (Mill.) DC. Prodr. 2: 256. 1825. Galega frulescens Mill. 

 Gard. Diet. ed. 8. Galega no. 5. 1768. This is, according to Btitten & Baker, Indigofera 

 mucronata. See Jour. Bot. 35: 225. 1897. 



Tephrosia lonoifolia (Jacq.) Pers. Syn. PI. 2: 32S. 1807. Galega longifolia Jacq. 

 Coll. 2: 349. l788.-^Ic. Rar. pi. 572. 1793. This is a species of Galactia. 



Cracca oroboides (H. B. K.) Kuntze, Rev. Gen. 175. 1891. Tephrosia oroboides 

 H. B. K. Nov. Gen. & Sp. 6: 462. pi. 579. 1823. This is evidently not a Cracca. The figure 

 seems to represent a species of either Anisolotus or Astragalus. 



Cracca lEpTosTachya (DC.) Rusby, Mem. Torrey Club 33 IS. 1S93. Tephrosia 

 leptostachya DC. Prodr. 2: 251. 1825. This has been reportedfrom Central America and 

 Mexico, but the specimens belong mostly to C. piscatoria and C. tenella. It is an African 

 plant, apparently introduced in South America. 



Cracca brevipes (Benth.) Kuntze, Rev. Gen. 174. 1891. Tephrosia hrevipes Benth. 

 Ann. Nat. Hist. 3: 432. 1839. This is a South American species, extending north into Trini- 

 dad; it has been reported from Porto Rico, but according to Urban the specimens on which 

 this record was based, probably came from Trinidad. See Symb. Ant. 4: 284. 1905. 



* The description is drawn from R. T. Lowe's specimen, collected January 29, 1866, in Santo 

 Domingo, now in the Gray Herbarium. It agrees very well with the description of T. hracleolala, 

 but is evidently not T. Ko'sckyana Hochsl., which is usually regarded as a synonym of that species.
