In fields and waste places, nearly through- out our area, and in warm and tropical America. Xative in the southwest, but naturalized north- ward. Widely naturalized as a weed in the warmer parts of the Old World. Summer. 2. Portulaca retusa Engelm. Notched or A\"estfrn Purslane. Fig. 1746. Portulaca retusa Engelm. Best. Journ. Nat.
