FOOTNOTES:[1]In most flowers the corolla is the conspicuous portion of the perianth, and is composed of united or separate petals, as the case may be. In some flowers the corolla is absent, and the calyx is the conspicuous portion.[2]About 30 species of Potamogeton occur in Michigan, among which the most conspicuous is Potamogeton natans, with elliptical floating leaves. For the identification of the species the Manual must be used.
