Astragalus,^ LEGUMINOS^. ]51

A. caryocarpus the calyx is more thickly hairy than in A. succulentus : hence I have been led to mark them 

 as varieties. I do not, indeed, possess the fruit of either; that of the former is well known, however; and Mr. 

 Lindley has observed of the latter ; " Its fruit is not certainly known. We suspect it to be of the same 

 nature as that of A. caryocarpus: at least, there is, in Mr. Doug'Ias' collection, a fruit of such a kind, 

 which does not appear to belong to any other of his species." This certainly goes far towards proving that 

 the finit is also alike in the two.

S. A. succumhens ; ubique hirsutus, caule procumbente flexuoso ramoso, stipulis parvis 

 oblongo-acuminatis, foliolis 5-jugis obovatis, pedunculis folio brevioribus, racemis capi- 

 tatis subovalibus, floribus (majusculis) patentibus laxis, stipulis lineari-subulatis podi-

Hab. On the barren grounds of the Columbia, and near the Wallawallah River, North-West America. 

 Douglas. — Flowers large, purple and white. The leguntes are very remarkable : when spread open, they are 

 broadly lanceolate, but there is, on one side, a deep sulcus, so that a transverse section represents the letter V. 



9. A, diaphanus ; prostratus, difFusus, piloso-s caber, stipulis parvis ovatis acuniiiiatis, 

 foliolis 5-9-jugis obovatis, pedunculis folio brevioribus, floribus (parvis) capitatis laxis, 

 bracteis ovatis acuminatis minutis pedicello subbrevioribus, leguminibus subreflexis 

 linearibus compressis falcatis subdiuphanis glabriusculis bilocularibus polyspermis.

Douglas, MSS. in Herb, Hort, Soc. 



Hab. Abundant on sandy soil near the Great Falls of the Columbia. — Flowers small, scarcely more 

 than half an inch long, " purple," fading, when dry, to nearly white. Legumes scarcely an inch long, much 

 flattened laterally, and falcate ; when mature subdiaphanous if held between the eye and the light, 



10. A, ientiginosus ; prostratus, glabriusculus, stipulis parvis ovatis acutis, foliolis 8- 

 jugis obovatis, pedunculis folio brevioribus, floribus — ? leguminibus ovatis acuminatis 

 membranaceis sursum curvatis basi inflatis bilocularibus glabriusculis. — Douglas, MSS> 



in Herb, Hort. Soc. 



Hab. Subalpine ranges of the Blue Mountains of North -West America. Douglas, — The flowers of this 

 do not appear to have been seen by Mr. Douglas ; but the fruit is very remarkable, and, as its discoverer 

 observes, considerably resembles that of A. tuberculosus, a native of Syria and Cappadocia. 



11. A. infleams; difFusus, prostratus, ubique villosissimo-tomentosus, caule flexuoso, 

 stipulis majusculis ovatis acuminatis, foliolis 9-10-jugis ellipticis acutiusculis obovatisve 

 obtusis, pedunculis folii longitudine, racemis laxis late ovalibus, pedicellis brevibus, 

 bracteis longis subulatis calycem membranaceum aequantibus, leguminibus ovato-acumi- 

 natis depressis bilocularibus tomentosis sursum insigniter curvatis. — Douglas, MSS, in 

 Herb, Hort, Soc, 



Hab. On the barren sandy grounds of the Coiumbia, from the junction of Lewis and Chirke's River to 

 the mountains. Douglas. —'Whole plant, except the large purple corollas^ woolly, with long hx hairs. Calt/x 

 long, cylindrical, with slender, wavy, subulate teeth, nearly as long as the corolla. Legumes an inch long, 

 ovate, and tapering a little at the base, but much more at the extremity, into a sharp point; compressed, (but 

 by no means flat,) and curved upwards, so as to be almost doubled, like the letter U; with a shallow, but 

 broad furrow below. The calyx is very thin and membranaceous, bursting when the fruit is ripe.
