Welcome to the PhytCore Website

Welcome to the PhytCore Platform. PhytCore aims to respond to the need for having a new open collaborative environment, which enables the participation of all researchers to find common consensus on phytolith nomenclature. The users of PhytCore will be able to promote discussions and suggestions for each new phytolith morphotype added to the database as well as to propose new classifications, which will be evaluated by a committee. Within each phytolith morphotype there will a space showing all different nomenclatures used for that specific phytolith (when appropriated), in order to facilitate the search and unification of the naming criteria. PhytCore will keep also the phytolith database open to any query or concern that you want to do. PhytCore aims to contribute to facilitate discussions among researchers to find a common consensus on phytolith nomenclature.

Would you like to particpate in PhytCore collaborative environment? Do you have phytolith images that you would like to add to PhytCore? Send us a message and we will send you all the necessary information to become a member of PhytCore and add your own images, so they can get to a wider audience.

International Code for Phytolith Nomenclature (ICPN) 2.0

We are pleased to announce that the new "International Code for Phytolith Nomenclature (ICPN) 2.0" is already published and available in Annals of Botany 124: 189–199, 2019 doi: 10.1093/aob/mcz064, available online at the following link:

Annals of Botany (ICPN) 2.0


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.
