|  I'm sure i have
                  some anecdotal information about this shot, but I'm
                  at a loss at the moment. | DESCRIPTION:
 A small (6 - 15") plant with clover-like
                  leaves branching from a main stem. Usually one to
                  several small yellow flowers only 1/2" across with
                  5 petals. The leaves are more heart-shaped than
                  clover and fold up along the main vein when the sun
                  goes down and open back up in the morning.
 FLOWERS:May to July
 HABITAT:Dry soil, roadsides, fields and waste
                  places.

               | OTHER INFORMATION:Probably the 2nd plant that children
                  learn, because the sourgrass is very tasty.
                  However, because of a large amount of oxalic acid,
                  it should not be consumed in any quantity. Taste
                  additions to salads are perfect.
 
                     
                        | 5 petals
                           and 10 stamens with the pistil erect. An
                           unfurled flower is right behind this
                           one. |
