downy, netted, or wrinkled longitudinally. The 

 mericarps are short and oval. 



Flowers may be found between May and August.

 from the parent plant. 



The plant is called Fowl-foot.

 illustration supplies an idea of the trailing habit of the 

 plant, as well as of the Hnnate leaves.

 allies. Some of the foreign types are related to the
