[Hebe salicifoliaG.福斯特（Pennell）]是一种木本被子植物，原产于新西兰和智利。属于唇形科的一种草本植物。施加膨胀力的反应木被发现在leaningH的下侧。柳叶茎这种反应木在被子植物中是非典型的，被子植物通常在倾斜的茎的上侧形成收缩的反应木。被子植物的典型反应木是由唇形科其他科的物种形成的。这表明，反应木的形式是特定的家庭水平。在功能上，H.杨柳叶与裸子植物中发现的相似，两者都通过推动来发挥作用。然而，它们的化学、解剖和物理特性是不同的。裸子植物反应木的典型特征，如高密度、厚壁圆形细胞和次生细胞壁层含有（1 → 4）-β-半乳聚糖等，在H中均不存在。柳叶木H.反应木salicifoliavaries从正常木材具有较高的微纤丝角，这是可能决定的方向产生的成熟应力。
Koromiko [Hebe salicifoliaG. Forst. (Pennell)] is a woody angiosperm native to New Zealand and Chile.Hebespp. belong to the otherwise herbaceous family Plantaginaceae in the order Lamiales. Reaction wood exerting expansional forces was found on the lower side of leaningH. salicifoliastems. Such reaction wood is atypical for angiosperms, which commonly form contracting reaction wood on the upper side of leaning stems. Reaction wood typical for angiosperms is formed by species in other families in the order Lamiales. This suggests that the form of reaction wood is specific to the family level. Functionally the reaction wood ofH. salicifoliais similar to that found in gymnosperms, which both act by pushing. However, their chemical, anatomical and physical characteristics are different. Typical features of reaction wood present in gymnosperms such as high density, thick-walled rounded cells and the presence of (1 → 4)-β-galactan in the secondary cell wall layer are absent inH. salicifoliareaction wood. Reaction wood ofH. salicifoliavaries from normal wood in having a higher microfibril angle, which is likely to determine the direction of generated maturation stresses.
