/40 SUP^LEMENTUM, 



inflexns. Sligma aciitum, glabrum. Legumina pen- 

 dula, oblongo-lanceolata, glabra, 3-4-sperma. 

 Of this plant I had ati imperfect specimen in the Lew- 

 isian Herbarium, together with some pods of an Astra- 

 galus, which led me into the error of placing it under 

 that genus ; but having since seen fine specimens in the 

 collection of Mr. Bradbury, I was enabled to correct 

 this error. 



Astragalus racemosus. — A. caulescens, erectns, subpube- 

 scens ; foliolis (21) lanceolatis superne sensim minori- 

 bus, stipulis ovatis acuminatis, spicis racemosis pedun- 

 culatis folio longioribus, densifloris, bracteis linearibus 

 pedicellis brevioribns, calycibus glabriusculis, dentibus 

 subulatis. 

 In Upper Louisiana. Bradbury. 1/ . v. s. in Herb. 

 Bradbury, flower white. Resembles A. carolinianus. 



Astragalus carvosus. — A. caalescens, diffusus, albido-seri- 

 ceus, foliolis (21) ellipticis supra glabris, subtussericeis, 

 stipulis subulatis, spicis subsessilibus^, leguminibus glo- 

 bosis inflatis carnosis. 



In Upper Louisiana. Bradbury, v. s. in Herb. Bradbury. 

 The fruit resembles that of A. psysodcs. Flowers ap- 

 pear to have been white. This is probably the A. cras- 

 sicarpus Fraser, catal. 1813. 



p. 4/3. Astragalus triphyllus. — A. acaulis, argenteus, foliis ternatis, 



foliolis sessilibus lanceolatis_, scapo nullo, leguminibus 

 sessilibus oblongis. 

 In Upper Louisiana. Bradbury. % . v. s. in Herb. 

 Bradbury. A most singular species, the leaves of a 

 shining silver colour ; the flowers were too much de- 

 cayed when I examined the specimens. 



Oxytropis Lambertii. — O. acaulis, sericeo pllosa ; foliolis 

 (19) lanceolato-ellipticis utrinque acutis, scapis folia 

 sequantibus, spicis capitatis, bracteis linearibus longi- 

 tudinecalycis. 

 On the Missouri. Bradbury. If.. Aug. Sept. v. v. in 

 Hort. Lambert. Flowers a beautiful purple. It ap- 

 proaches near to O. argentata and setosa. 



p. 474. Dalea auren. — D. sericeo-villosa ; spicis oblongis termina- 



libus solitariis, bracteis oblongis acuminatis calycis lon- 

 gitudine ciliatis, calycibus villosissimis, foliis sub-3- 

 jugis oblongis obovatisque obtusig.
