an adjective signifying autumnal (from phthinoporon, "late autumn," from phthino, "to waste away," or "wane," and opora, "autumn"), is used in Jude 1:12 , where unfruitful and worthless men are figuratively described as trees such as they are at the close of "autumn," fruitless and leafless (AV, "trees whose fruit withereth").
