three. The tube of the calyx, in all of them, is beset with 10 rows of glands, 

 altei'nating with the 10 ribs.

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

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

 pinnately 5-foliolate 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 exceed 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 glands. 



X D. Jamesii (Torr. 8f Gray, Fl. 1. p. 308): nana, cano-sericea, eglandulosa; 

 caulibus csespitosis e caudice lignescente ; stipulis setifoi'mibus elongatis persistenti- 

 bus ; foliis palmato-trifoliolatis argenteo-nitentibus ; foliolis obovatis vel oblongis 

 obtusis vel acutis ; spicis cylindraceis sessilibus ; bracteis oblongis aristato-acumina- 

 tis villosis flores subgequantibus ; calyce villosissimo, laciniis aristseformibus longe 

 plumosissimis tubo duplo longioribus corollam flavam nunc purpuream subtequanti- 

 bus. — Coll. of 1851, in fruit and flower. There is no appearance of glands.* 



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

 glabratis ! spicis incanis prfelongis. — Eastern Texas, in an early collection made by 

 Mr. Wright. — This shows that even A. canescens greatly varies, like the other 

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

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



t A. paniculata, Torr. 8f Gray, Fl. 1. p. 306; Engelm. 8f Gray, PI.' 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 underneath. 



•f A. laevigata, Nutt. in Torr. 8f Gray, I. c. ; var. pubescens : foliolis retusis 

 (9-15 lin. longis) supra glabellis subtus cum petiolulis ramulis spicisque majusculis 

 molliter cinereo-pubescentibus. — Eastern Texas. — The leaflets are as softly pubes- 



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



+ No. 126 of Rugel's Florida collection, wrongly named "A. canescens, Nutt.," is A. herbacea, Walt., 

 and A. pumila, Miclix., the more pubescent form (A. pubescens, Willd.) ; and of this, the A. glabra, Desf., 

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

 ascertained. A. Tennessensis, ShuUleworth, PI. Ritgeh, is either a form of this or of A. fruticosa, I am 

 uncertain which. A. pumila and A. herbacea of Schlecht. Hort. Halensis, 1848, Linncea, 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, Bot. Mag. t. 

 2112; also with No. 595, PL Lindh. 2. p. 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.
