2. O. Lambérti, Pursh. Silky with fine appressed hairs; leaflets mostly linear; flowers larger, purple, violet, or sometimes white; pods cartilaginous or firm-coriaceous in texture, silky-pubescent, strictly erect, cylindraceous-lanceolate and long-pointed, almost 2-celled by intrusion of the ventral suture.—Dry plains, Sask. and Minn. to Mo. and Tex., west to the mountains.
[*][*] Leaflets numerous, mostly in fascicles of 3 or 4 or more along the rhachis.
3. O. spléndens, Dougl. Silvery silky-villous (6–12´ high); scape spicately several to many-flowered; flowers erect-spreading; pod ovate, erect, 2-celled, hardly surpassing the very villous calyx.—Plains of Sask. and W. Minn., to N. Mex. and the Rocky Mts.
23. GLYCYRRHÌZA, Tourn. Liquorice.
Calyx with the two upper lobes shorter or partly united. Anther-cells confluent at the apex, the alternate ones smaller. Pod ovate or oblong-linear, compressed, often curved, clothed with rough glands or short prickles, scarcely dehiscent, few-seeded. The flower, etc., otherwise as in Astragalus.—Long perennial root sweet (whence the name, from γλυκύς, sweet, and ῥίζα, root); herbage glandular-viscid; leaves odd-pinnate, with minute stipules; flowers in axillary spikes, white or bluish.

Tall (2–3° high); leaflets 15–19, oblong-lanceolate, mucronate-pointed, sprinkled with little scales when young, and with corresponding dots when old; spikes peduncled, short; flowers whitish; pods oblong, beset with hooked prickles, so as to resemble the fruit of Xanthium on a smaller scale.—Minn. to Iowa and Mo., and westward; Ft. Erie, Ont.

Calyx 2-lipped; the upper lip 2-, the lower 3-cleft. Standard roundish; keel boat-shaped. Stamens diadelphous in two sets of 5 each. Pod flattened, composed of several easily separable joints.—Leaves odd-pinnate with several pairs of leaflets, sometimes sensitive, as if shrinking from the touch (whence the name, from αἰσχυνομένη, being ashamed.)
1. Æ. híspida, Willd. Erect, rough-bristly annual; leaflets 37–51, linear; racemes few-flowered; flowers yellow, reddish externally; pod stalked, 6–10-jointed.—Along rivers, S. Penn. to Fla. and Miss. Aug.
