I recall a long time ago reading a science-fiction book that contained a word to describe a character that I didn't recognise. When I looked it up, I learned it meant 'of or pertaining to bushes.'
It was a word ending in '-ine' like psittacine (pertaining to parrots) or ursine (pertaining to bears) but I can't for the life of me remember what it was.
It's also proving impossible to google, with results ranging from "just use 'bushy' you cabbage" to pejoratives for certain US presidents...
Can anyone help?
