single country, when the plants themselves are not so limited. The "standardized" common name, in its more artificial form, all too often appears as a mechanical translation of the scientific name: thus, Eleocharis acicularis becomes slender spikerush; E. obtzusa, blunt spikerush; E. parvula, dwarf spike- rush; and E. quadrangulata, squarestem spikerush. The fri- volity of these names becomes quite apparent when one con- siders that these species, together with a score or more of others, are very closely related and in many cases cannot be distinguished except by microscopic examination. Such syn- thetic common names are excluded from this Checklist. Considerable effort has been given to reflecting, by the way the common name is spaced or hyphenated, the actual relationships of the plant. Thus, Rhoeo spathacea is known as boat-lily and Asparagus plumosus as asparagus-fern, since the first is not a lily and the second is certainly not a fern, while Lilium catesbaei is known as pine lily and Nephrolepis biserrata as sword fern, with common names reflecting their true alliances. Occasionally, where long-established usage has made the adjective an integral part of the name, the combined form is accepted, as in clubmoss, pondweed, and bluegrass, but such barbarisms as Bermudagrass and St. Augustinegrass have been avoided. Supplemental Literature Considering the richness and uniqueness of the Florida flora, a relatively limited list of publications is available dealing with the identification of the native and naturalized plants. Only certain genera and a very few families have been treated in sufficient detail. In most cases one must depend upon regional studies, which of necessity give scant information about the flora of any single state. The following publications, some of which are semi-popular and others comparatively technical, are important aids in the identification of the flora of Florida. Baker, M. F. 1938.
