Abstract:

The introduction emphasizes historical aspects of umbelifer taxonomy and offers a brief phytogeographical sketch of Apioideae of Peninsular Spain and the Balearic Islands. The characters used in the study are then analyzed, paying special attention to those with greatest diagnostic value, such as the type of ridges, number of vitae, and the form of the endosperm in transverse section. The evolution of some of these characters is discussed, indicating the primitive and successive derived states. Description of fruits are preceded by keys. Four groups are recognized within the Apioideae according to: 1) the nature of the ridges (primary and/or secondary); 2) the development of the primary marginal ridges relative to dorsal ones; 3) the development of secondary ridges into wings, and 4) the elongation of secondary ridges into spines. After the description of the fruits of each taxon, date is presented concerning: 1) the phenology of the fructification; 2) the ecology, and 3) the general distribution of the taxon. The material used for the carpological study is indicated, and for each taxon a distribution map within the study área is given in an appendix. The maps were created utilizing both verified herbarium materials and biblio¬ graphic sources including classical Spanish Floras and Peninsular botanical journals.
