Excluded and imperfectly known species 



Astragalus bidentatus H.B.K. Nov. Gen. & Sp. 6: 493. 1824. The species was described 

 from a plant of unknown origin, and there is no indication that it came from Mexico. The description 

 is full except as to the pod, which was not known, and accompanied by a good illustration. No similar 

 plant has been collected since in North America. Jones' claim (see Rev. Astrag. 189), that 

 it might be the same as .4. guatemalensis Hemsley and that the figure might be inaccurate, has no 

 ground whatever. 



Astragalus carnosus Pursh, Fl. Am. Sept. 740. 1814. This is Sophora sericea, the fruit 

 excepted. 



Astragalus deklexus Pall. Acta Acad. Petrop. 2: 268. 1779. This was later transferred by 

 De Candolle to Oxytropis. 



Astragalus frutescens Kunth, Ind. Sem. Hort. Berol. 1845: 12. 1845. This is the same as 

 Brongniartia podalyrioides (see N. Am. Flora 24: 189). 



Astragalus Lambertii Spreng. Syst. 3: 390. 1826. This was based on Oxvtropis Lambertii 

 Pursh, Fl. Am. Sept. 740. 1814. 



Astragalus leptopus Benth.; A. Gray, PI. Wright. 2: 43. 1853. This is only incidentally 

 mentioned, and A. cobrensis is compared with it. There is no diagnosis, but the plant was found in 

 Coulter's Mexican collections. 



Astragalus Helleri Fenzl, Bonplandia 8: 56. 1861. The description of this species is ample, 

 but the type has not been accessible. The species is compared with A. mexicanus. A. caryocarpus, 

 A. plattensis, and A. Irichocalyx, and the plant should then belong to Geoprumnon. No species of this 

 genus, however, has been collected in later years in southern Mexico. The type came from the 

 neighborhood of Mount Orizaba, Veracruz. 



Astragalus pasqualensis M. E. Jones. Rev. Astrag. 78. 1923. This is the same as Indigofera 

 aculijolia Schlecht. (see N. Am. Flora 24: 144. 1923). One specimen cited there belongs, however, 

 to I. nana Rydb. (he. oil. 143). 



Astragalus recticarpus Wood, Bot. Gaz. 3: 50. 1878. This is Indigofera leptosepala Nutt. 

 (see N. Am. Flora 24: 143. 1923). 



Omitted synonyms 



Astragalus junceus A. Gray, Proc. Am. Acad. 6: 230. 1864. This synonym was omitted 

 under Homalobus junceus Nutt. (see page 267). 



Astragalus odoratus Ell.; D. Dietr. Syn. PI. 4: 1080. 1S47. This is given as a synonym 

 under A. EllioUii, and is evidentlv an error for A. obcordatus Ell. (see Batidophaca obcordala, page 

 321). 



Astragalus orthocarpus Dough; A. Gray, Proc. Am. Acad. 6: 196. 1864. The name appears 

 only as a synonym of A. canadensis L. 



Astragalus palans araneosus M. E. Jones, Proc. Calif. Acad. II. 5: 673. 1895. A synonym 

 omitted under Cysticum araneosum (see page 410).
