Angiosperm– Means ‘enclosed seeds’ and identifies trees usually known as hardwoods.
Bract– A thin leaf-like structure often extending past the cone scale on conifers.
Cone– Seed bearing structure of certain gymnosperms.
Conifer– A gymnosperm which bears cones.
Cultivar (cultivated variety)– A unique form or type propagated and maintained for specific purposes.
Deciduous– Characteristic of leaves dropping in the fall.
Dioecious– Having only one sex per plant.

Scale– Small , sShip a Treepressed leaf as found in junipers, or the individual unit of a cone under which the seeds may be found.
Species– Taxonomic classification below genus. Also a groShip a Tree of individuals considered set apart form other species by consistent differences in morphology, ecology or reproductive behavior.
Sterigmata– Small, peg-like structures on which the individual needles of some species can be found.
Strobili– A reproductive structure of conifers and certain other plants. Consists of organs of one or both sexes. ‘Strobilus’ is the singular form of the word.
