Sedges: Carex is the fourteenth volume of the Illustrated Flora of
Illinois series and the sixth and last volume devoted to
monocots--plants that have a single seed leaf, or cotyledon, upon
germination.
Since the volume's original publication in 1999, thirty-four additional
species of plants have been recognized in Illinois. Some are discoveries
from recent field work, some are from more thorough searches of
herbaria, and others are from different taxonomic philosophies.
For each species of Carex in Illinois, there is a full illustration
showing the habit of the plant and close-ups of various vegetative and
reproductive structures that are crucial for the identification of the
individual species. There is also a complete description of each species
as well as a detailed discussion of the nomenclature and habitats. Range
maps show the county distribution of each species in Illinois. A new and
detailed key is provided for identification of the species.
