 cent : leaflets 1 to 3 pairs, oblong-obovate, obtuse, 2 or 3 lines long : flowers purple, 4 

 lines long, very nearly sessile : calyx half as long, somewhat pubescent ; the teeth

 Thurb. 316 ; Watson, Bot. King Exp. 65. 



On rocks near Muddy Eiver, S. Nevada (Fremont) ; also by Lieut. Wheeler in the same region.

 appressed silky, the lax spinulose branches and foliage yellowish-green : leaflets 1 to 

 4 pairs, oblong, obtuse, 2 or 3 lines long ; the terminal longer, linear-oblong : flowers 

 scattered upon the branchlets, nearly sessile, purple, 3 or 4 lines long : calyx finely 

 pubescent ; the shortly acuminate teeth equalling the tube, shorter than the corolla : 

 pod small, pubescent. Bot. King Exp. 64, t. 10.

-t- -t- Leaves simple. 



10. D. Schottii, Torr. Shrubby, slender, nearly glabrous, somewhat spinose, 

 the branches nearly glandless : leaves scattered, narrowly linear, an inch long : 

 flowers few, on short slender pedicels in an open raceme, sometimes solitary, purple, 

 4 lines long : calyx half as long, obscurely glandular ; the teeth very short, acutish : 

 ovary pubescent, 2-ovuled : pod 4 lines long, with a single large seed. Bot. Mex. 

 Bound. 53. 



Banks of the Colorado, near Fort Yuma (Schotf) ; Colorado Desert, Palmer. 



11. D. spinosa, Gray. A shrub, much branched and very spinose, 4 to 15 feet 

 high, hoary with a minute appressed pubescence : leaves scattered, cuneate- oblong 

 or nearly linear, obtuse, nearly sessile, 4 to 8 lines long, very deciduous : flowers 

 nearly sessile, in a loose spike, purple, 5 lines long : calyx half as long, marked by 

 a row of conspicuous glands, the broadly ovate obtusish teeth much shorter than the 

 tube: ovules 6: pod twice longer than the calyx, 1-seeded. PI. Thurb. 315; 

 Torrey, Pacif. R. Rep. vii. 9, t. 3. Asagraea spinosa, Baillon, Adansonia, ix. 232. 



On Carico Creek (Antisell), in the Colorado Desert (Thurber), and eastward on the Gila. Made 

 a distinct genus by Baillon, mainly on the larger number of ovules and the simple leaves. 



12. GLYCYKRHIZA, Linn. LIQUORICE. 



Flowers nearly as in Astragalus. Stamens monadelphous or diadelphous : anther- 

 cells confluent at the top, the alternate anthers smaller. Ovary sessile, 2 many- 

 ovuled : style short and rigid, curved at the tip. Pod ovate or oblong-linear, com- 

 pressed and often curved, scarcely dehiscent, few-seeded, glandular or somewhat 

 prickly. Erect perennial herbs, glandular-viscid ; leaves unequally pinnate ; stip- 

 ules deciduous ; flowers in dense axillary pedunculate spikes, with caducous bracts ; 

 root large and sweet. 



About a dozen species, found in all quarters of the globe but Africa ; only one North American. 



1. Gr. lepidota, Xutt. Tall and stout (2 or 3 feet high), somewhat glandular- 

 puberulent, or the younger leaves slightly silky : leaflets punctate, 6 to 8 pairs, oblong- 

 lanceolate, mucronate and often acuminate, usually an inch or two long : spikes 

 short : flowers ochroleucous, nearly 6 lines long : calyx half as long ; the slender 

 teeth much longer than the tube : pod thickly beset with hooked prickles, oblong, 

 6 lines long, 2 - 6-seeded. Hook. Bot. Mag.' t. 2150 ; Torr. & Gray, Fl. i. 298.
