AGRIMONIA L. Sp. PL 448. 1753. 



Perennial, erect or assurgent, mostly glandulose herbs, simple 

 or branched above, with alternate, conspicuously stipulate, odd- 

 pinnate leaves bearing interposed subleaflets, and small regular 

 perfect yellow flowers in spicate racemes. Flowers short-pedi- 

 celled or subsessile, axillary from small 3-cleft' bracts and with a 

 pair of tnfid or entire bracteoles at the base of the calyx. Calyx- 

 tube in fruit obconic, turbinate or hemispheric, short-stipitate,sul- 

 cate, uncinate-spinose or bristly above, contracted at the throat to 

 form a flattened or convex disk which supports a central process 

 formed by the five connivent calyx-lobes. Petals 5, inserted with 

 the 3-1 5 stamens in the margin of a waxy disk which surrounds the 

 terminal styles in the throat of the calyx ; anther-cells mostly 

 separated by a broad connective. Carpels 2, included, developing 

 into one or sometimes two one-seeded achenes with membranous 

 testae contained in the indurated calyx tube, seeds suspended. 



Leaflets crenate, dentate, serrate or incised, the teeth mucronu- 

 lete or having a minute callosity in the tip. Lower stipules smaller 

 and simpler than those above. Stamens variable in number in the 

 some species, often fewer than normally in the terminal or. later 

 flowers. Roots either fibrous or tuberous-thickened. 



The North American species, as far as known, are as follows. 



The ranges given are based alone on specimens actually examined, 



and are doubtless subject to considerable extension in some cases.
