To search simply begin typing. Once you have entered several characters a list of suggestions will appear. These suggestions are only the first dozen or so entries that match what you have typed. (NOTE: There may be more matches; press ENTER to see the full list.) If you continue typing the list of suggestions will change.

If you see the item you are searching for in the list, you can select it by clicking on it with the mouse, or by using the arrow keys to scroll down, then select it by pressing the ENTER key.

Note that the suggestions only match to the beginning of words.

Alternatively, you can type some text to search for and hit ENTER, ignoring the list of suggestions. A list of matching items will appear under the search box. Note that in this case, the search matches your text to anywhere in the name, e.g. rata will match Baloghia marmorata, Cupaniopsis serrata, and so on.
