The degree of correlation between shoot organization characteristics and systematic groupings is examined, and the utility of these characteristics for systematics is evaluated. Some patterns which appear are pointed out: taxa with bisexual flowers usually produce a single inflorescence at the terminus of a vegetative article. A few taxa with bisexual flowers produce pairs of inflorescences at the ends of articles.
Multiple inflorescences more than two at an article terminus occur only among taxa with unisexual flowers. Multiple inflorescences are associated with anisophyllous or homeophyllous sympodial growth, while single or paired inflorescences are associated with homeophyllous or intermittent homeophyllous sympodial growth. These patterns might be understood as the result of selection for flexibility of reproductive effort and of seasonal reproduction.

The three patterns of carpel vasculature occur in Clade B and deserve to be investigated in a larger number of species, particularly from A. A possibility is that Pattern A could be a plesiomorphy for all Anthurium species, given that it is also found in other species of A. However, the lack of samples from other sections precludes a clear distinction between these two patterns and reinforces the importance of vasculature data in the genus.

Abstract Introduction and Aims Anthurium is the largest genus of Araceae, with species distributed in the neotropics. Methods We compare the floral vasculature of 20 neotropical species belonging to distinct sections of Anthurium , using both light and confocal laser scanning microscopies.
Results The number and position of vascular bundles are constant within the tepals and stamens, regardless of the species and sections studied. Conclusions The variation in the supply to the carpels in Anthurium is corroborated here. Table 1 Comparison of early classification systems with the recent phylogeny of Anthurium.

Materials and Methods Neotropical representatives of four traditional sections of Anthurium , mainly distributed in Brazil, were selected for the present study Table 2 ; Fig. Table 2 Specimens of Anthurium examined and respective collections.

Floral vasculature Based on our sample of 20 species of Anthurium from four distinct sections Table 2 , two patterns of floral vasculature were observed, related primarily to the carpellary supply.
