achene

achene , dry, simple, one-seeded fruit with the seed attached to the inner wall at only one point. Achenes are indehiscent, i.e., they do not split open at maturity. The so-called seed of a sunflower is an achene; the shell is the wall of the fruit, and the true seed lies within. A strawberry consists of many achenes embedded in a fleshy receptacle.
