the confusion concei'iiin^y If. Jamesii and IT. meJanoiiUvta. The claAVS 

 of the petals and the style furnish some iiu])oitaiit ehuracters. The 

 pod furnishes some of the most iiuijortiiut si)efilic distinctions, but can 

 not be of prime impfn'tance in ^n-ouping, for tlie fniit of a species and 

 its varieties may differ widely.

 «'r(M'pin<;- root (hcurin^ n<)w and tlu'ii a tnlx'r), ]>iilierulfiit, sparsely ^lamliiliir, 

 S(!arioiis at base: leaxcs with 7 to 11 ]Mmia'; leatlct.s (5 to 10 i)airts, ptihcriilfiit or

 vexilluin wliieli has a thick dihited elaw: outer stamens with copious <'lavate 

 ^laudt* : pod falcate, 3 to 4 em. long, with round apex and acute base, on recurved 

 pedicel, more or less glaiidul.ar, com])resse<l betw<'eu tlu^ 8 to 12 dark obovate 

 seeds. 

 Haltitat : From Southern Arizoua tlirough Mexico (Sau Luis Potusi) to Chili and 

 Patai><)nia. 



S]iecimens examined : Arizinia (Lemmou, 1X81, in part); San Ijuis I'otosi (Schajfiier 

 832, 1876); Argentine Kepublic {at Cordova, 1829; l*ata<;onia, .Uulreus 333); Chili 

 {Morong 1191; y'AiWtjj's distribution 1321); also Hpeeimcns cultivated at th(( botanical 

 gardens of Montpellier (l«24)an<l l)<'lile (1821). 



This j)olyniorphie spe,<^ies has a wid(! distribution, and has Ijeou heretot'orc! divided 

 into several species and varieties. The specimens ibund in the ITnited States and 

 Mexico have been called //. ntnela with its var. demixfa, and //. denx'ijtora, whibitlutse 

 of South America ami those cultivated in France have been called H. fah-nvia. Mr. 

 Heutliani remarks that "the above s])ccies (//. sfrieta, deminxit and deiinijlttra) agi'ce 

 -with If. falcaria in their most imi>ortaut characters," but does not state how they 

 ditl'er. The only ditVerence yet uoti<e(l between the Xnrlli and South American forms 

 is that th(^ latter have ovaries with few<'r j;lauds and the corolla is oiteu a deeper yel- 

 low; otherwise theyagri'c. Some oT the Moiong speciuu'ns arc very low, erect, very 

 glainlular, with rather <lense racemes; while others ar»! 45 cm. high, with long loose 

 racemes. It dill'crs from var. strtila in being jirocnmbeut and Jia.vitig tlu^ mature 

 fiuit roun<led at a]wx, ;ipproa<diiug that <(f //. drcpanomrpa in mosi respects. 'I'he 

 S<'hat1'ner and Lemmon specimens agree with the deseriptiou of //. faharia, but 

 they agree more with tlie plants themselves. 'i"he tbllnw iug seem to be well uiarked 

 varieties : 



Var. STHH'TA. Erect, 10 to 30 em. high: stipules obtuse, villous on margin: pe- 

 duncles long, bearing a loo8»^ rac<'nie of auberect liowers: serials obtuse: vexillum 

 with (!la,\\ usually more dilated: )iod hnig, obtuse or acute, uamilly on s])reji<liug 

 pedicels; seeds tJ tit 9.
