E. Bessey, how- ever, reports^ in the Fern Bulletin that it is becoming a weed in several wet meadows in Nebraslca. Campbell asserts that it is an annual, but upon this point more notes are desirable. Mr. Eaton is of the opinion that while the leaves may die the rootstock does not. Like an exotic species, Marsilia liirsnta, it is said occasionally to bear tuber-like bodies on the ends of certain branches of the rootstock, which under proper conditions may pro- duce new plants. Marsilia JVLacrop...oda. The species called Marsilia macropoda is like Marsilia vestita in being more or less hairy, but it has a longer rootstock, much larger leaves, and sporocarps that are borne in clusters of from two to four instead of singly. It also probably lives longer than Marsilia vestita. ^[arsilul Vestita, THE MARSILIAS. 201 The rootstock of this species is like that of Marsilia quadrifolia in being wide-creeping. It grows beneath the water and sends up its large leaves to the surface. These are often two inches or more across, with deltoid seg- ments having a rounded outer edge.
