nameless tree, or, being a proper Japanese woman

As Poirot once said, what you and I don't know could fill volumes. And one of those volumes would be a book about plants—flowers and trees and such. With that in mind, I am thinking of learning the names of flowers and trees, so that when I come across one, I would know what in the world I was looking at.

Some people can hear birdsong and identify the bird singing. I'm not particularly interested in birds, but I like flowers and trees, so this should be fun...

It'd also be nice to be able to identify musical instruments in orchestral pieces, or maybe voices of singers...or maybe composers of classical pieces? Or maybe spices in cooking. Or fish? Like, if I eat a fish, I'd know what in the world it was...

Is that what being a connoisseur is...?
