The summer has been dry and hot continuously, and remains so going into September.  Underneath a Large Leaf Maple tree in our neighborhood,  I found on the ground a few fallen wilted dry leaves still full of rich colors in lemon yellow, umber and ocher plus a (helicopter) seed.  The leaves that remain on the tree appear fresh and green waiting for the cooler nights to change their colors.

This dry summer has caused stress to the deciduous and evergreen trees on the island due to lack of water so I am assuming these leaves are the first to leave the branches.
