    (Universidad de El Salvador, 1953-03-01) Fassett, Norman C.
    This paper is a taxonomic study of the genus Cerathyllum as it occurs in the western Hemisphere north of the Equator. The field work in Central America Was done from 20 September 1950 to 13 March 1951,while the writer was a guest at the Instituto Tropical de Investigaciones Científicas; this was made possible by the cooperation of the Wisconsin Alumni Research Foundation and the Chicago Natural History Museum. The facilities of the Gray Herbarium were graciously made available during the spring of 1951.For loans of herbarium material the writer is indebted to the curators of the Chicago Natural History Museum,the Missouri Botanical Garden,the New York Botanical Garden,the University of California, and the United State National Museum.The leaves of Ceratophyllum are borne in whorls of from 6 -10 at the each node,and are cut into many slender divisions.It is the mass of bushy overlapping leaves toward the tip of the stem that gives the plants its common name of “Coontail”.
