PULSE FAMILY. Leguminosae. 



This species has similar flowers, but 

 Desmodium they are considerably larger and borne 



grandiflorum Qn glender gtalk which riseg from th 

 Pale magenta 



June- plant-stem at the point where the leaf- 



September stalks spring outward. The broad, 

 pointed leaflets are much larger and a 

 trifle hairy. The strange seed-pod like that of the fore- 

 going species is 2-3 jointed. The name is from detfjuoS 

 a chain, alluding to the connecting joints of the pod. 

 By means of these joints the pods attach to the furry 

 coats of animals. 1-4 feet high. The same distribution. 



Desmodium The stem of this silkv liail T tick trefoil 



rotundifolium bends or lies near the ground. The leaflets 

 Purple- are quite round, comparatively speaking, 



** nta soft-hairy, and not pointed. The flowers 



September are ^S^t purple-magenta, and the pod 

 3-5 jointed, constricted nearly equally at 

 both edges. 2-5 feet long. About the same distribution. 

 Desmodium Tnis s P ec i es ^ as oblong lance-shaped 



Dilienii leaflets, or quite ovate ones, nearly if not 



Pale magenta quite smooth above, an erect and nearly 

 Jul smooth stem, and branching flower-stalks 



bearing very small pale magenta flowers. 

 Pod 2-4 jointed, the sections nearly triangular. 2-3 feet 

 high. Not farther south than Va. and Ky., west to Neb. 

 Desmodium -^ st ^ narrower-leaved species, the deep 



paniculatum green leaflets scarcely 2 inches long, and 

 Pale magenta linear lance-shaped, resembling willow 

 JUly ~ h leaves. The flower-spikes are rather hori- 



zontally branched ; Pale magenta flowers 

 very small. Pod 4-6 jointed. The slender stem 2-3 feet 

 high. Common. 



The most showy species of the genus, 



Tref ^t| an TfCk with crowded flower-clusters terminating 



Desmodium a tall > stout, and hairy stem. The leaves 



Canadense are nearly without stalks, or with short 



Dull magenta- ones, and the three leaflets (longer-stalked) 



are oblong lance-shaped. The flowers 



September (larger than those of the other species) are 



nearly inch long, and vary in color from 



magenta to magenta-pink. Pods 3-5 jointed and quite
