Lilaeopsis chinensis, natural size, Fraland Beach, July 15, 1934. Photographs by K. D. Doak. Prior to 1933, the herbarium of the Academy of Natural Sciences of Philadel- phia contained only two specimens of Scirpus americanus collected in Delaware. The state was not represented by specimens in the herbarium of the Philadelphia Botanical Club. Spartina alterniflora Lois., var. pilosa (Merrill) Fern., another plant with which Lilaeopsis chinensis is associated, is also inadequately represented in col- lections from the state. Both of these plants are widely distributed in Delaware. They follow the tidal streams which ramify the marshes. Lilaeopsis chinensis, on the other hand, is closely confined to the lower shores of the Delaware River and the upper shores of Delaware Bay. Lilaeopsis chinensis does not extend inland but remains on the shore of the Delaware where its physiological requirements seem best satisfied. On the shore, the colonies form dense mats which rarely extend more than two or three yards inland from the edge of vegetation. The species extends up the river to Ham- burg Cove, where it was collected at a point four miles south of Newcastle, and goes southward along the shore for approximately thirty miles to a point about one and one-half miles south of Fraland Beach. The plant has been col- lected at a number of intermediate points, and, within this range, it appears adapted to the existing conditions. These conditions vary considerably. At Delaware City and Pea Patch Island, Lilaeopsis formed dense turf-like colonies on tidal mud beneath Scirpus americanus. Scirpus validus Vahl was also pres- ent in the association. At Augustine Beach, growing on tidal mud, Scirpus americanus appeared in a pure stand above the Lilaeopsis turf. In the upper part of the range, Lilaeopsis chinensis grows bes
