PINK AND ROSE-COLORED FLOWERS 
GROUP VII 
Leaves otherwise than opposite or whorled. Herb. Leaves of 
three leaflets. 
Showy Tick Trefoil {Desmodium canadense). Pulse family. 
July to September. 
An upright perennial one foot to several feet high. The 
flowers are papilionaceous, magenta, one-half inch long, in 
raceme; the calyx is two-lipped. The leaves are made up of 
three leaflets, lance-shaped to oblong, blunt, with slender, 
pointed, persistent stipules. The pods, two to three inches long, 
have three to five joints, and proceed directly from the calyx. 
Found in woods and on banks, perhaps more common in the 
open country than the other Tick Trefoils, which are prone 
to seek the shelter of the woods. The Greek name signifies a 
chain, referring to the jointed pod. 
Panicled Tick Trefoil {Desmodium paniculatum) . Pulse 
family. July to September. 
A trefoil with a tall and slender stem and delicate branches 
leaving it at right angles. The small papilionaceous flowers are 
in a loose panicle. The leaflets, with tiny and temporary stipules, 
are very narrowly lance-shaped with blunt points ; the pods are 
rather short-stalked and sometimes have six joints. 
Dillen's Tick Trefoil {Desmodium Dillenii). Pulse family. 
June to September. 
An upright plant with hairy stem two to three feet high', 
with papilionaceous flowers only about one-fourth inch long. 
The three leaflets are egg-shaped to lance-shaped, pale beneath, 
two or three inches long, with small stipules ; the leaf -stalks are 
an inch or more long. Pods, rather short-stalked, of two to 
four joints. Common in open woody places.
