I spent a lot of time as an NPS naturalist and USFS forester with those scientific names, but in case you haven't checked lately, many of those are changing, as are the families and connections up that chart as they work out the genome connections between plants. Like the lotus and the plane tree being close relatives (or is it the water lily and the plane tree? At any rate, lotus and water lily aren't actually related, apparently.) It's almost not safe to go out in the garden with your old botanical key any more. ;-D
