Surely we have seen a flower like this before – the Primrose in the little coppice. Yes; the Primrose had five pale yellow petals, rather larger than those of the Cowslip, and joined together to form a corolla; they grew out of a long green calyx. Also each petal had a spot of darker yellow in the centre of the blossom. The leaves of both the Primrose and the Cowslip are much wrinkled, and they grow from a short underground stem.
But, you say, each Primrose blossom grew alone on the top of a long stem. Yes, but if we had dug up a Primrose plant, we should have found that several flower stems grew from the same point – the top of a very short stem which hardly appeared above the ground. They grew from an umbel, and the Primrose is closely related to the Cowslip. The difference is that the blossoms of the Primrose grow on long stems from a short-stemmed umbel. Those of the Cowslip grow on short stems from a long-stemmed umbel.
