Wood Collectors primarily collect samples of plants from the group of seed plants, Spermatophytes. This can be either softwood (Gymnosperms) and hardwood (Angiosperms)
Wood however, is composed of various types of tissue, which wood collectors should be able to recognize and name in order to assign a particular species. Tissue which occurs abundantly in one species and is an important feature, can be completely absent in a different species. To see the right features, to name and describe them, is the most important for determination. The recognition of wood types can be done, among others, by the study of micro preparations.
Micro preparations of wood are thin slices of wood of 10-15 microns thick, cut into 3 planes:
a) In the transverse plane for example, the vessels, the distribution of vessels, the type and the distribution of the parenchyma (ground tissue), the number of rays per mm and the thickness of the fiber wall can be seen.
