Sedges of the British Isles.

"The long awaited 3rd edition of The Sedges of the British Isles is now available. The handbook has been considerably expanded in size, with the scope of the book widened by the addition of 35 species not previously described, thereby covering all the British and Irish species. All confirmed hybrids have also been included. Distribution maps for each species/hybrid are now adjacent to each entry and along with the text have been updated. Introductory chapters on structure, classification, ecology and hybridisation are followed by keys, entries, glossary, bibliography and indices to English and Latin names." --NHBS Environment Bookstore.
