术语在描述和理解生物体的形态和解剖变异方面起着至关重要的作用。植物物种的巨大多样性及其对广泛生态系统的许多形态和生理适应性反映在木本组织的巨大解剖变异上。这也许有些令人惊讶，因为被子植物木材基本上只由三种细胞类型组成：固定的管分子（纤维和管胞）、导管分子和活薄壁细胞。然而，这些细胞的尺寸和排列的变化给任何旨在描述和理解木材样品之间定量和定性差异的人提供了挑战。挑战不仅在于术语的一致应用和解释（透镜et al. 2012），而且在于我们如何处理动态连续体（即，Agnes Arber & RolfSattler意义上的模糊形态），包括过渡，中间形式，类似和同源特征（Sattler & Rutishauser 1997）。
Terminology plays a crucial role in describing and understanding the morphologicaland anatomical variation in living organisms. The huge diversity in plant species andtheir many morphological and physiological adaptations to a wide range of ecosystemsis reflected in an enormous anatomical variation of woody tissues. This is perhapssomewhat surprising given that angiosperm wood consists of essentially three cell typesonly: imperforate tracheary elements (fibres and tracheids), vessel elements, and livingparenchyma cells. However, variation in the dimensions and the arrangement of thesecells provide a challenge to anyone who aims to describe and understand quantitativeand qualitative differences between wood samples. The challenge lies not only in theconsistent application and interpretation of terms (Lens et al. 2012), but also in howwe deal with a dynamic continuum (ie, fuzzy morphology sensu Agnes Arber & RolfSattler) that includes intergradations, intermediate forms, analogous and homologousfeatures (Sattler & Rutishauser 1997).
