﻿34 PLANTS FENDLERIAN^. 



146. A. diphysus (sp. nov.) : subglaber, depressus, caulibus numerosis e radice 

 perpendiculari crassa adsurgentibus ; stipulis triangularibus acuminatis scariosis basi peti- 

 oli adnatis ; foliolis 9-10-jugis carnosulis obovato-oblongis saepe retusis ; pedunculis 

 folium ajquantibus ; racemo spicato densifloro brevi ; pedicellis bractea ovato-subulata 

 persistente calyceque cylindraceo brevioribus ; corolla caerulea ; leguminibus membrana- 

 ceis inflatis ovatis acuminatis sursum arcuatis suturis utrinque introflexis subdidymis com- 

 plete bilocellatis polyspermis nitidis. — Plains, around Santa Fe, in red sandy soil, of a 

 low and depressed growth, but forming patches one or two feet in diameter ; April to 

 May. Mr. Fendler further remarks, that he never observed this plant to be eaten by any 

 animal whatever. — This species produces a thick cluster of stems, 6 to 10 inches high, 

 from the same fleshy root, and in appearance is not unlike A. caryocarpus and A. tricho- 

 calyx, but is smoother, having only sparse and minute appressed hairs on the stems and 

 petioles, and sometimes on the midrib of the otherwise glabrous leaflets ; and the flowers 

 are smaller (barely half an inch long). The pods are remarkably different, being of a 

 thin and membranaceous or papery texture, didymous and inflated, about an inch long at 

 maturity, pointed and incurved. It is equally distinct from the little-known A. pachycar- 

 pus, Ton. #• Gray; which bears a legume that has evidently been succulent before 

 ripening, and when dry exhibits the same thickened and cellular walls as those of A. 

 caryocarpus aud A. trichocalyx, with which it should be associated. 



147. A. diphysus /3. albiflorus. With the preceding, apparently differing only 

 in the white flowers. The specimens show no fruit. 



148. A. cyaneus (sp. nov.) : subcaulescens ; caudice multicipiti ; stipulis triangu- 

 laribus vel subulato-lanceolatis ; foliolis 9-14-jugis ovato-rotundis ovalibus oblongisve 

 cum petiolis pube minuta strigulosa appressa utrinque griseo-canescentibus; pedunculis 

 scapoideis folia subajquantibus angulatis ^8- 12-floris ; pedicellis brevissimis bracteam 

 subulatam aequantibus ; calyce pilis griseo-nigricantibus appresso-pubescentibus, dentibus 

 subulato-setaceis tubo cylindrico dimidio brevioribus ; corolla cyanea ; leguminibus carti- 

 lagineis puberulis rugulosis oblongo-linearibus acuminatis sursum curvatis turgidis poly- 

 spermis sutura dorsali profunde sulcata introflexa incomplete bilocellatis, sutura ventrale 

 extus prominente. — Santa Fe, on gravelly hills and low mountains among rocks ; April, 

 May. — A larger plant than A. Missouriensis, which the species most resembles in habit, 

 foliage, and flowers ; the mode of growth much as in the preceding, but almost acaules- 

 cent. Leaves crowded at the summit of the branches of the caudex or on the abbreviat- 

 ed flowering stems, 3 to 6 inches long ; the leaflets one fourth, or sometimes nearly one 

 half, an inch in length, hoary with a close and fine strigulose pubescence. The pedun- 

 cles or scapes are stout and erect, 4 to 8 inches long in fruit. The flowers are almost an
