flowerless

The earliest forms of which we have any knowledge were flowerless plants, which produced minute spores instead of seeds.

There are about 110,000 species of flowering plants and nearly as many flowerless plants.

Writing of these flowerless beauties, I am tempted to exclaim again, "Happy the humble!"

Its stem is thin but hard, and much branched, the numerous flowerless branches usually forming a dense tuft close to the ground.
