    Is this a school quiz?... because I don't want to answer your homework. The question is confusing to me. Several grasses grow underwater and a quick internet search turned up two distinct genera that can grow in water without roots in the soil. Can you clarify the question?

    I guess the question is not precise enough. I did the same search and several grasses (true grasses) grow underwater (we have all seen images of flooded rice fields.) I also did a search for floating grass and found two that survive floating in the water. There may be more. I stopped searching after that. My guess would be that the answer is Oryza sativa (rice), but the question is wrong.

    Maybe the questioner meant 'only grass native to Britain [or to Lincolnshire?] that can actually grow in water'?, with the expected answer Common Reed Phragmires australis? (tho' even that isn't wholly true, there are other grasses here which will grow in water, they're just less common).

    Any references to nature and physiology that use absolute terms like "never", "only", "always", etc are on pretty shaky ground. Any examiner setting multiple choice questions should know that - unless, the question is deliberately designed to trip the poor student up!
