Abstract
Taxonomic and herbarium revision of the genus Fumana (Dunal) Spach (Cistaceae) coupled with field surveys in Croatia yielded several interesting new data. Two overlooked and poorly known species, Fumana scoparia Pomel and Fumana laevis (Cav.) Pau, are confirmed for Croatian flora. The existence of Fumana ericoides (Cav.) Gand. has not been confirmed and all actual Croatian populations are ascribable to morphologically closely related Fumana ericifolia Wallr. Particular attention is paid to the confusion between the two taxa in the Mediterranean flora, and morphological features for their distinction are specified. Consequently, seven taxa are currently regarded as being present in Croatia: Fumana arabica (L.) Spach, F. ericifolia Wallr., Fumana laevipes (L.) Spach, F. laevis (Cav.) Pau, Fumana procumbens (Dunal) Gren. et Godr., F. scoparia Pomel and Fumana thymifolia (L.) Spach ex Webb. Each taxon is described and diagnostic characters, such as the indumentum type and seed morphology are given. An identification key, original line drawing for F. scoparia and distribution maps for all species of the genus Fumana occurring in Croatia are provided.
