Analysis of some species of the genus Anthurium (Araceae) based on morphological characters Sílvia Lima Oliveira Santos, Fabio Giordano

Abstract

The genus Anthurium is the largest of the Araceae family, but so far few systematic studies have been done. Among the described species, it is believed that at least 101 are endemic to Brazil, justifying the relevance of knowing and preserving this biodiversity. The present study aimed to demonstrate possible groupings of ten species, through a cladistic analysis, based on plant morphological data. A bibliographic research and technical visit to the Botanical Garden Plantarum was carried out in Nova Odessa, SP, where the species were randomly selected. The data were compiled in a table of the morphological characters, regarding the presence or absence, which generated a numerical matrix used in the PAST software. The Cluster Analysis was performed, and through Jaccard's similarity index, it generated a dendogram. The present study can contribute to the systematic analysis of the species and knowledge of the biodiversity of the species.
