 alternating with the 10 ribs.

 of the Pecos, and on mountains near EI Paso ; Aug., Sept. — This interesting 

 plant so much resembles D. Jamesii tliat there is scarcely any thing besides the 

 pinnately 5-foIioIate and narrower leaflets to distinguish them. The leaflets are 

 from 5 to 8 lines long ; the setiform stipules are shorter, and the pappus-like calyx- 

 segments perhaps longer, than in D. Jamesii. These excecd the short and rounded 

 lamina of the vexillum, are fully as long as the wings, but scarcely equal the keel. 

 The specimens are all far advanced ; and are entirely destitute of

t Amorpha canescens, Nuttj var. glabrata: foliolis parce pubescentibus mox 

 glabratis ! spicis incanis pra^Iongis. — Eastern Texas, in an early collection made by 

 Mr. . Wright — This shows that even A. canescens frreatlv varies. 



canescens greatly varies, like thc othei 

 .species, as to pubescence. The leading spike is nearly a foot in length, much longei 

 than in Engelmann's var. leptostachya, Pl Fendl. No. 125. f 



t A. paniculata, Torr. ^ Gray, Fl. 1. 'p. 306 ; Engelm. 8r Gray, Pl. Lindh. p. 7. 

 Eastern Texas, in an early collection, made by Mr. Wright. — Remarkable for its 

 very dense and long canescent spikes of small flowers, as well as for its large leaf- 

 lets, which are prominently pinnately-veined undemeath.

* No. 7013 of GalGottl's Mexican collection is Dalea leucostachys, Gray^ FL Fendl. p. 32, or near it, 

 t No. 126 of Rugers Floridacollection, wrongly named " A, canescens, iVi/«.," isA. herbacea, WalL, 

 and A. pumila, Michx., the more pubescent form (A. pubescens, Willd.) ; and of ihis, the A. glabra, Desf.^ 

 and A. Carollniana, Crooin, are merely the glabrous variety, as Mr. Curtis and Dr. Chapman have well 

 ascertained. A. Tennessensis, Shutlleicorlh, PL Rugel^ is either a form of this or of A. fniticosa, I am 

 uncertain which. A, pumila and A. herbacea of ScMechL IIorL Halensis^ 1848, Linnda^ 24. p, 185, of 

 which Prof. Schlechtendal has kindly sent me fine specimens, must belong to one species, notwithstanding 

 a small difference in the fruit; and they agree with A. Lewisii, Loddiges^ and A. nana, BoL Mag.L 

 2112 ; also with No. 595, FL LindL 2. jp. 174. The fruit of all these is shorter, straighter, and usually 

 thicker, and the leaflets are mostly attenuate at the base and firmer in texture, than in the true A. frutico- 

 sa : but whether they form a distinct species is not so clear.
