In a recent issue of Castanea (33: 123-135. 1968) my paper, “Contributions to the Flora of Florida—4, Fimbristylis (Cyperaceae)'”, used the long accepted name Fimbristylis monostachya (L.) Hassk. for a pantropic species found on calcareous soils in Dade and Monroe counties, Florida, with one outlying station known in Citrus County. This distinctive sedge has at times been treated as a segregate under the name Abildgaardia monostachya (L.) Vahl (e. g., J. K. Small, 1933). These names are based on Cyperus monostachyos, a 1771 name and description by Linnaeus (Mantissa Plantarum 180), and are supported by a specimen in the Linnaean herbarium.
