Most genera of the Brassicaceae are difficult to determine as all available dichotomous keys are based on characters from different developmental stages (e.g. rosette leaves, flowers, fruits, seeds), which are rarely available in one specimen. Furthermore, almost every morphological character used to define genera is homoplastic and therefore, immediate identification using simple dichotomous keys is often difficult. This Interactive Key allows to select all characters, which can be scored (including geographical origin) from the material available, and enable quick identification.
The Interactive Key has been prepared by Ihsan A. Al-Shehbaz with use of NaviKey (Neubacher & Rambold, 2005; http://www.navikey.net) algorithm. It enables quick identification of Brassicaceae genera based on a combination of characters and can be useful even when a number of features are missing.
