Abstract This article enumerates the anatomy of the leaves, petioles and stems of Ocotea nutans (Lauraceae) illustrated with optical and scanning electron micrographs. The anatomical markers include the presence of sclerenchyma in the midrib and the absence of trichomes in the leaves. The presence of brachysclereids and prismatic crystals in the petioles and stems is new to the genus Ocotea and reported here for the first time. The key findings of the present study can contribute to the taxonomy and quality control of Ocotea nutans.

Ocotea nutans (Nees) Mez (Lauraceae) 的显微镜和组织化学

摘要 本文列举了 Ocotea nutans (Lauraceae) 叶、叶柄和茎的解剖结构，并用光学和扫描电子显微照片进行了说明。解剖标志包括中脉中厚壁的存在和叶子中毛状体的缺失。在叶柄和茎中存在短柄和棱柱状晶体对 Ocotea 属来说是新的，这里是第一次报道。本研究的主要发现有助于 Ocotea nutans 的分类和质量控制。
