MADCAP HORSE

For some reason, this just popped into my head today. It's a mnemonic I learned for tree and shrub identification: MADCAP HORSE. It is used to help you remember which trees and shrubs have opposite leaves. It works here in NJ at least.

Maples
Ashes
Dogwoods
CAPrifoliaceae - viburnums and honeysuckles*
HORSE Chestnut

*I think viburnums are now in the family Adoxaceae, so this may be a bit confusing

I'm sure there may be exceptions to this mnemonic, but it's worked for me.

I teach horticulture as a high school senior elective. We use a variant of this for our class. We don't do shrubs so we just use MADHORSE. I did find out this year that there is actually a dogwood called the Alernate-leaf Dogwood (named for its alternate branching).

Dan - Why didn't they have classes like that at my HS?

Mike - Say what? Too long for you?

FYI, not only elderberry but also Viburnums are now part of Adoxaceae rather than Capfifoliaceae. Also, not sure why adoxaceae was left out of this mnemonic? AMADCAPHORSE (the first a for adoxaceae) is how I learned it. It is suppose to be comprehensive for all northern hemisphere opposite and woody plants.
