The Palm-ID knowledge base enables to identify the palm stems on an anatomical level. Descriptors and their states described here are implanted in the Computer Aided Identification (CAI) software (a knowledge base manager) Xper2 (Vignes-Lebbe et al., 2010) that makes possible interactive identification.

The Palm-ID knowledge base contains 31 descriptors (in 7 groups as cortex, central cylinder, fibrous vascular bundles…) with 97 states and 37 taxa (subfamily, tribes and genera). 500 figures are also included to facilitate the identification. During the identification, the polymorphism is undertaken with the use of logical operators. All the descriptions can be analysed in detail: check base function, discriminant power of the descriptors, and comparison of the taxa.

A simplified version of the base enables to identify the same taxa with only the least polymorphic descriptors (the most robust).

Currently, all the palm subfamilies are included but only the Coryphoideae were the subject of a detailed anatomical study.

The Xper web page (english and french) has a detailed documentation of the software with a Use FAQ, demo video, guideline...
