deciduous

views updated

deciduous Applied to parts of a plant or animal that are shed seasonally (e.g. deer antlers, leaves of certain plants), to trees that shed their leaves seasonally, and to the perianth of a flower if this is shed after fertilization. In trees, this is not an indicator of taxonomic status; although deciduous trees are generally angiosperms, some (e.g. larch) are gymnosperms.
