(Fragaria nipponica nipponica)
Fragaria nipponica is a species of wild strawberry native to the western side of the Japanese island of Honshū, with a variety Fragaria nipponica var. yakusimensis on Yakushima. Some botanists treat it as a synonym of Fragaria yezoensis. All strawberries have a base haploid count of 7 chromosomes. Fragaria nipponica is diploid, having 2 pairs of these chromosomes for a total of 14 chromosomes. Strawberries are not true berries.The fleshy and edible part of the fruit is a receptacle, and the parts that are sometimes mistakenly called "seeds" are achenes.Although it is commonly thought that strawberries get their name from straw being used as a mulch in cultivating the plants, the etymology of the word is possibly derived from "strewn berry" in reference to the fruit being "strewn" about the base of the plants
