Abstract
Calluna vulgaris (Ericaceae) is an economically important crop for the European horticultural sector.
Within the species the so-called bud-flowering phenotypes represent the most significant subgroup.
Since several other flower phenotypes exist and classification of these is considered as an important matter for future breeding, a study of flower organ identity based on molecular and morphological aspects was started.
We discuss our results within the context of earlier classifications of specific cultivars into botanical subgroups.
As a consequence, we propose some re-classifications of relevant cultivars.
Furthermore, our results proved perianth organ identity as well as the identity of bracts in the wild-type phenotype and the bud-flowering group.
