边缘带是双子叶植物叶的一种新结构，在该器官的形成中起着重要作用。它沿着叶的两个边缘出现，在个体发育的栓阶段，为几列近轴表皮细胞。在功能上，它似乎是许多次级特征的预模式，包括（i）在山月桂中看到的所有叶中存在的边缘生长分生组织，（ii）在鼠尾草和冬青中看到的成排的裂片和刺，（iii）在绣球属的一些品种中的色素沉着，（iv）在Kalabe pinnata的小植株中的繁殖，（v）在荚属和冬青属的一些品种中用于支撑的边缘脊，以及（vi）如鹤望兰属中用于叶片分隔的边缘坏死。© 2003 The Linnean Society of伦敦，Botanical Journal of the Linnean Society，2003，143，21-28。
The marginal band, a newly described structure of the dicot leaf, plays an essential role in the formation of this organ. It arises along the two edges of a leaf as several files of adaxial epidermal cells during the peg stage of ontogeny. Functionally, it appears to serve as the prepattern for a number of secondary features including (i) the marginal growth meristem present in all leaves as seen in mountain laurel, (ii) rows of lobes and spines as in Salvia and Ilex, (iii) pigmentation as in some cultivars of Hydrangea, (iv) propagation as in the plantlets of Kalanchoe pinnata, (v) marginal ridges for support in a few varieties of Viburnum and Ilex, and (vi) marginal necrosis as in Strelitzia for blade partitioning. © 2003 The Linnean Society of London, Botanical Journal of the Linnean Society, 2003, 143, 21–28.
