| Abstract | ||||
| Leaf and fruit cuticular features (cell form and / or epicuticular secretions) were studied in the Macaronesian endemic tree Apollonias barbujana (cav.)Bornm. using SEM and / or LM. In addition, the macromorphological and floristic aspects of the genus were surveyed. The results were then compared with similar features in 19 available taxa of the Lauraceae representing the tribes Laureae and Perseeae (Five taxa from the present study and 14 compiled from Literature). The data obtained were analyzed by the NT sys- pc program package using the UPGMA clustering method. The produced dendrograms were discussed. The study showed that Apollonias occupies a relatively isolated position in the family with affinities to both the Laureae and the Perseeae. The significance of cuticular features in the taxonomy of the Lauraceae was referred to, and a revision of the suprageneric classification of the family as suggested by Rohwer, 2000 is now strongly supported. | ||||
