  1. These biological terms allow to link ecologically relevant information to the images and vice versa. We ascertain that there is pressing need to extend controlled vocabularies such as the cell or plant ontologies with semantic terms specifically addressing phenotypic characters in bryophytes. This is because many existing terms were originally defined for vascular plants which have, for instance, dominant sporophytes and multicellular leaves which are different from the dominant gametophytes and unicellular leaves usually present in bryophytes.
