156 NORTH AMERICAN FLORA [Volume 24 



Flowers in axillary racemes ; leaves odd pinnate, ex- 

 cept in some species of Coursclia and occasion- 

 ally in Ohicya; banner mostly spreading. Subtribe 8. Robinianae. 

 Pods more or less inflated or completely or partially 

 2 -celled, by the intrusion of one or both sutures. 

 Style bearded along the upper margin ; pods always 



1-celled. Subtribe 9. ColuTEAnae. 



Style glabrous, or bearded only around the stigma 

 Anther-cells not confluent; pods not prickly; 



plant not glandular-dotted. Subtribe 10. AsTRAGALANAE. 



Anther-cells confluent at the apex; pods in ours 



prickly; plant glandular -dotted. Subtribe 11. Glycyrrhizanae. 



Subtribe 1. CRACCANAE. Herbs or shrubs, with alternate odd-pinnate 

 leaves, persistent stipels, and no stipels, the leaflets usually with parallel 

 oblique lateral veins. Flowers racemose, the racemes mostly terminal and 

 in the upper axils, or opposite the leaves, or (in Galcga) axillary. Calyx cam- 

 panulate, 5-lobed, the upper lobes often more or less united higher up. Corolla 

 papilionaceous, the petals more or less clawed. Banner broad, more or less 

 spreading. Stamens monadelphous or diadelphous. Style glabrous, more or 

 less hairy around the stigma. Pod elongate, flat, 2-valved, obliquely striate. 

 Seeds usually reniform or transversely oblong, i.e., their longer axis in the axis 

 of the pod; strophiole if present very small. 



Stipules not spinescent; lateral veins of the leaflets prominent. 



Upper filament wholly united with the staminal sheath, forming a closed tube; 



banner in ours glabrous. t. GalEga. 



Upper filament free, at least at the base; banner in ours silky-strigose on the back. 2. Cracca. 

 Stipules spinescent; upper filament wholly free; lateral veins of the leaflets obsolete. 3. Peteria. 



1. GALEGA L. Sp. PI. 714. 1753. 



Perennial herbs. Leaves odd-pinnate, with semi-sagittate stipules. Flowers in axillary 

 and terminal racemes, with narrow bracts and no bracteoles. Calyx campanulate, with 5 

 subequal lobes. Corolla white or light-blue. Banner obovate-oblong, narrowed below into a 

 short claw. Wings with oblong blades adherent to the keel at the middle and with a prominent 

 basal auricle. Keel-petals obtuse, straight or nearly so to near the apex, where they are strongly 

 arcuate, longer than the wings, united nearly their whole length. Stamens monadelphous, 

 the upper filamejit united with the sheath for at least half its length; anthers uniform or 

 the alternate ones slightly smaller. Ovary sessile, many-ovuled; style incurved, glabrous; 

 stigma small, terminal. Pod linear, terete, 2-valved, the valves obliquely striate. Seeds 

 transversely oblong, without strophiole. 

 Type species, Galcga officinalis L. 



1. Galega officinalis L. Sp. PI. 714. 1753. 



A perennial herb; stem 5-10 dm. high, glabrous, growing in tufts; leaves about 1 dm.

 long, glabrous; racemes 1-1.5 cm. long; bracts subulate, persistent; calyx-tube 2 mm. long, 

 glabrous, the lobes subulate-setaceous from a deltoid base, 3 mm. long; corolla light-blue 

 or white, about 1 cm. long; wings with an oblong reflexed basal auricle; pod linear, glabrous, 

 4 cm. long, acuminate at both ends, somewhat torulose.
