He hit upon a very simple and very useful method of plant identification. He pointed out FOR FAST GREENS that the number of stamens in a flower is always the same in the same kind of plant—any flower in the Iris family, for example, always has three, any flower in the Amaryllis family has six, and so on. This classification system was most effective, but Linnaeus himself realised that it was not a natural one. Plants with the same number of stamens were not necessarily closely related. For instance, the mint, with its opposite leaves, square stems, strong smell and four stamens is obviously related to the sages which share these characteristics—and different only in the FIT A GRASS COMB number of the stamens, sages only having two.
