Identify the leaves as they are distinctive and key to species recognition.

1. Check that leaves are alternate on the stem, simple, ovate, and have tiny spikes or holly-like teeth on the edges.
2. Note the leaf size and shape, which resemble little boats—this is a helpful mnemonic for remembering their appearance.

Look for the characteristic flowering structures and fruits during their respective seasons.

1. Identify green and yellowish catkins, as well as green and reddish female flowers that are spiked.
2. Note that the tree produces brown acorns, typically in winter, which are an important identifying feature.
