Having no flowers; lacking flowers or being flowerless.
From Greek 'an-' (without) + 'anthos' (flower) + '-ous' (full of, having). A direct Greek construction meaning 'without flower' applied to plants that never flower.
Mosses and ferns are ananthous—they look green and plant-like but reproduce through spores instead of flowers, representing an ancient strategy that worked for hundreds of millions of years before flowers evolved!
