740 SUPPLEMENTUM. 



inflexus. Siigma acutum, glabrum. Legumina pen- 

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

 Of this plant I had an 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. Eradbury, I was enabled to correct 

 this error. 



Astragalus racemosits. — A. caulescens, erectus, subpube- 

 scens ; folioiis (21) lanceolatis superne sensim minort- 

 bus, stipulis ovatis acurainatis, spicis racemosis pedun- 

 culatis folio longioribus, densifloris, bracteis linearibus 

 pedicellis brevioribns, calycibus glabriusculis, dentibus 

 subulatis. 

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

 Bradbury, flower white. Resembles A. carolinianus. 



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

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

 stipulis subulatis, spicis subsessilibus, leguminibus glo- 

 bosis intiatis carnosis. 



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

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

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

 sicarpus Fraser. calal. 1813. 



p. 4/3. Astragalus triphyllus. — A. acanlis, argenteus, foliis ternafis, 



folioiis sessilibus lanceolatis, scapo nullo, leguminibus 

 sessilibus oblongis. 

 In Upper Louisiana, Bradbury. Ij. . 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-pilosa ; folioiis 

 (ip) lanceolato-ellipticis utrinque acutis, scapis folia 

 sequantibus, spicis capitatis, bracteis linearibus longi- 

 tudinecalycis. 

 On the Missouri. Bradbury. 21 ■ Aug. Sept. v. v. in 

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

 proaches near to 0. argentata and setosa. 



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



libus solitariis, bracteis oblongis acuminatis calycis Jon- 

 gitudine ciliatis, calycibus villosissimis, foliis sub-3- 

 jugis oblongis obovatisque obtusis.
