Glossary

  • Coppicing: traditional form of woodland management in which trees are cut close to the base of the trunk. Re-growth occurs in the form of many thin poles. Woodlands are cut in this way on rotation, producing a mosaic of different stages of re-growth.
  • Deciduous: a plant that sheds its leaves at the end of the growing season.
  • Leaflets: the individual 'leaf-like' parts of a compound leaf.
  • Pinnate: in plants, a compound leaf where the leaflets (individual 'leaves') are found on either side of the central stalk.
  • Sepals: a floral leaf (collectively comprising the calyx of the flower) that forms the protective outer layer of a flower bud. (See http://www.rbgkew.org.uk/ksheets/pdfs/flower.pdf for a fact sheet on flower structure).
  • Styles: an elongated part of the female reproductive organs of a flower that bears the stigma (the receptive area where pollen germinates), usually at its tip. (see http://www.rbgkew.org.uk/ksheets/pdfs/flower.pdf for a fact sheet on flower structure)
