Oh, treeeees! You're so kind. Here I was, assuming you were going to try to get me with the old cuppa-through-the-slot-in-the-door trick (almost as famous as the squirting-daisy-in-the-lapel trick)... but no! You're a paragon of cuppa-offering kindness. If I'd done a bit more observation, I would have seen that.
Favorited (though I do think you should re-name this list "Treeeees!" in order to make it an anagram of your name).
Edit: Or, since you included mollusque, "Emulous Treeeees... LQ." (Are there any other users you could add? Not sure what to do about those last two letters.)
Edit No. 2: For instance, if you added bilby, you'd get "bouquet sublimely" and then you'd just have to deal with the extra letters EEELRS, which could at least spell eels, or leers, or reels, etc.
Edit No. 3: And if you then included fbharjo, it would be appropriate to start by spelling
"beryllium."
In an old textbook I came across by chance (long story), it mentions sausage tree and umbrella tree. I hadn't heard of them before but I thought of this list!! ;-)
Added both, thanks! Mollusque, since you expressed interest in "stealing" this list, I've added you as a contributor. Have at it! Looking forward to seeing how it turns out, since this started as a sort of catch-all for tree words from other lists. :-)
