Glycyrlilza Icpulota, Nutt. (WILD LIQUORICE.) (The genus may 

 be known from Astragalus, which it considerably resembles in foliage and in

 Roots long, perennial, sweet; stern 2 -3 high; leaflets 7 to 9 pairs and an 

 odd one, oblong-lanceolate, mueronate-pointed, sprinkled with little scales when 

 young, and with corresponding dots when old ; spikes peduncled in the axils of 

 the leaves, short ; flowers whitish ; pods oblong, scarcely dehiscent, beset all over 

 with hooked prickles, so as to resemble the fruit of Xanthium on a smaller scale.
