"Francie Nolan" Trees

There are several "Francie Nolan" trees outside my window. Oh, that 
is not their official, botanical name. It is what I call them because that
is the species of tree Betty Smith used to symbolize Francie Nolan in
"A Tree Grows In Brooklyn."
Sometimes, when I look at those trees, I imagine that they are
palm trees on a tropical island. And, in fact, they are on an island.
After all, Brooklyn is, geographically, a part of Long Island.
