Many scientific terms that are being used are derived from Latin and Greek words. Prof. H.T. Clifford spent eight years doing research after the etymology of all the terms used for naming grasses. The result is an elaborate interactive glossary of more than 13,000 terms and their explanations. A multimedia introduction section explains about general rules of taxonomy and naming these organisms that are so important for agriculture. ETI's computer software assists in quickly finding your way to names and explanations. A must for both experts and students.
