Check your page source code - you'll probably find it there.
You shouldn't be calling mysql_real_escape_string() on data which is to
be displayed. It should only be called for data you're passing on a
database call.
And if you're going to display it, you should be calling htmlentities as
you display it.
Don't keep the data in your program in either mysql or html encoded
format. Keep the pure string and just massage it as necessary, ie.
<input type='text' size='57' name='latin_name'
value="<?php echo htmlentites($latin_name); ?>">
Also note that I'm not using short tags. Too many hosts have it disabled.
