 tiolulate, dotted, the lowest pair approximated to the stem ; flowers subsessile; 

 teeth of the calyx nearly equal, short, acute or acuminate; vexillum nearly 

 white. — Walt. Car. p. 179; Nutt. gen. 2. p. 91 ; IJC. I. c. A. pubescens,

 "Shrubby rather than herbaceous" {Ell.), 2-4 feet high. Leaflets obtuse or 

 acute, sometimes very small. Calyx purplish.

On the woodless and grassy hills of the Missouri from the Platte to the 

 mountains, Nuttall ! (v. s. in herb. Lamb.) Plains of the Red River, Brit- 

 ish America, in lat. 50°, Boiiglas. May. — An exceedingly compact shrub, 

 with copious foliage and very small rigid leaflets, punctate with rather large 

 sparse pellucid dots. Calyx also glandular. Hook. Flowers purplish-blue 

 and fragrant. Nutt. — The figure of A. nana in Bot. mag. t. 2112, is referred 

 by Hooker to A. fruticosa. 



5. A. Californica (Nutt. ! mss.) : "shrubby, pubescent ; leaflets elliptical- 

 oblong, obtuse, rather distant, conspicuously dotted with brownish glands be- 

 neath; petioles furnished with minute glandular scales; stipules broad and 

 membranaceous; spike short and solitary; teeth of the villous calyx all acute 

 and short ; bracts lanceolate, acuminate. 



" St. Barbara, CaUfornia; near the coast. May. — Shrub rather lower than 

 A. fruticosa. Leaves in the young state almost villous. Bracts and stipules 

 brownish, caducous. The fully developed flowers not seen." Nuttall. 



6. A. Icevigata (Nutt. mss.) : "glabrous and very smooth; leaves large; 

 leaflets distant, elliptical-oblong, attenuated below ; the common petiole short ; 

 stipules minute ; bracts rather long and subulate, caducous ; calyx very glan- 

 dular ; the teeth acute, the 3 lower ones longer and acuminate ; vexillum deep 

 blue, about the length of the calyx ; legume 1-seeded. 



"I3anks of the Arkansas, near Salt River. — A very distinct large shrubby 

 remarkably smooth species, with large distant and very obtuse leaflets, and 

 long (8-10 inches) clustered terminal spikes. Calyx nearly glabrous except 

 the margin, covered with elevated glands." Nuttall. — This species we have 

 Dot seen. It is apparently allied to A. paniculata. 



7. A', panictdata : whole plant canescently tomentose, except the upper 

 surface of the leaves which is nearly glabrous and shining; leaves on distinct 

 petioles; leaflets 7-8 pairs, elliptical-oblong (1^-3 inches long), petiolulate, 

 very obtuse and often emarginate or retuse at each end, dotted and promi- 

 nently veined beneath ; spikes numerous, virgate, in a large nearly naked ex- 

 serted branching panicle; flowers subsessile; teeth of the glandular and to- 

 mentose calyx unequal ; the 2 upper triangular-ovate and shorter ; the 3 low- 

 er triangular-subulate, the middle one somewhat longest; vexillum (purple) 

 broadly cuneiform, truncate, one-third longer than the calyx. 



Arkansas, Dr. Leavenworth! Texas, Drummond! — Stem stout and ap- 

 parently tall. Leaves 8 inches to a foot or more in length. Stipules not 

 seen. Panicle often a foot or more long, compound. Spikes 6 inches ia 

 length, the flowers much crowded : bracts setaceous, caducous. 



8. A. canescens (Nutt.) : sufTruticose, rather low, softly canescent ; leaves 

 sessile, very numerous and crowded; leaflets 15-24 pairs, closely approxima- 

 ted, elliptical or ovate-elliptical (very small), mucronate, at length rather rigid
