Identification Hints: Overcup oaks are found in the southeastern United States. They are commonly found in wet areas, such as lowlandsand can grow up to 66 feet tall. The leaves of the Overcup oak have rounded lobes and the shape of the entire leaf is somewhat of an elongated-lobed oval. A distinguishing feature of the Overcup oak is the acorns. In this species the acorncap covers more than half of the nut.

Did you Know? The phenology of Overcup oak helps it resist spring flooding. The leaves of Overcup oaks come out a month or more later than many other species that grow in the same areas. The flooding often kills off species whose leaves come out earlier and providing Overcucreates a competative edge for the Overcup oaks to grow.

The table below displays all the data that has been submitted to Project BudBurst. By default, the data is sorted by the date on which the phenophase occurred. Clicking the up and down arrows next to each column name allows you to sort on any value. If there have been more than 10 observations submitted, you can choose how many to display at a time using the "Show __ entries" control. You can also page through the data using the previous and next buttons at the bottom right of the table.

The Search box allows you to search all of the data. Searching by date, species, phenophase, etc. is easy—just start typing and the table will immediately change to contain only observations that contain your search phrase. Do you want to see only 2012 observations? Just type "2012" in the search box. Only want to see maples? Enter "Acer." You can combine searches, too! Searching for "acer 2012" will narrow your results to only the maples that were observed in 2012 (assuming that any observations exist, of course).

Once you have your results in the order desired, you can use any of the buttons above the search box to copy the results to the clipboard; save them as a text, or spreadsheet; or even print them from your browser!
