Stomatographical features in the systematics of the Magnoliaceae

摘要

The results of a detailed stomatographical study of the Magnoliaceae are compared with findings of recent work on seed morphology, branch initiation pattern, floral scent chemistry and molecular systematics. Their significance for the classification of the family is assessed and on their combined basis, the outlines of a possible improved classification of the family are presented. Several genera as currently circumscribed - Magnolia, Talauma, Aromadendron and possibly Dugandiodendron - appear not to be natural groups and the generic structure of the subfamily Magnolioideae, currently in dispute, clearly requires revision. The recognition of 15 genera in the subfamily would be in accordance with the stomatographical data, but the delimitation of tribes and subtribes remains problematical.
