Opal phytoliths (microscopic silica bodies produced in and between the cells of many plants) are a very resilient, often preserved type of plant microfossil. With the exponentially growing number of phytolith studies, standardization of phytolith morphotype names and description is essential. As a first effort in standardization, the International Code for Phytolith Nomenclature 1.0 was published by the ICPN Working Group in Annals of Botany in 2005. A decade of use of the code has prompted the need to revise, update, expand and improve it.
ICPN 2.0 formulates the principles recommended for naming and describing phytolith morphotypes. According to these principles, it presents the revised names, diagnosis, images and drawings of the morphotypes that were included in ICPN 1.0, plus three others. These 19 morphotypes are those most commonly encountered in phytolith assemblages from modern and fossil soils, sediments and archaeological deposits. An illustrated glossary of common terms for description is also provided.
蛋白石植硅石（许多植物细胞内和细胞间产生的微观硅体）是一种非常有弹性的植物微化石，通常能被保存下来。随着植硅石研究数量的指数级增长，对植硅石形态类型名称和描述进行标准化是至关重要的。作为标准化的第一步努力，国际植硅石命名法规 1.0 由 ICPN 工作组于 2005 年在《植物学纪事》上发表。该代码使用十年后，需要对其进行修订、更新、扩展和改进。
ICPN 2.0 制定了命名和描述植硅石形态类型的推荐原则。根据这些原则，它呈现了修订后的名称、诊断、形态类型的图像和绘图，这些形态类型包括 ICPN 1.0 中包含的以及另外三个形态类型。这 19 个形态类型是在现代和化石土壤、沉积物和考古沉积物中的植硅石组合中最常遇到的。还提供了一个常见描述术语的插图词汇表。
