The Araceae are exceptionally diverse by nearly all phenetic criteria. The two most widely
accepted infrafamilial classification systems, those of Engler and Hutchinson, emphasize …

All the steps leading to anther opening, pollen presentation, and dispersal are reviewed and
discussed. The main aspects are anther dehydration and its mechanisms, pollen …

The chromosome numbers of 75 species belonging to the family Araceae have been
determined. The numbers for 53 species are reported for the first time. One number differs …

The identity of the oldest lineage of monocotyledons is a subject of debate. Alternative
interpretations of morphological homologies are variously consistent with proposals that …

Flower development and anatomy of Acorus calamus and flower anatomy of A. gramineus

The history of classification of the genera Acorus and Gymnostachys, generally considered
to constitute the tribe Acoreae in the family Araceae, is briefly reviewed. Phenetic data …

The chloroplast trnL‐F region was used as an independent data set for phylogenetic
analysis of 118 aroid taxa. We investigated the intergeneric relationships of subfamily …

This volume covers up-to-date notions of seed structure, processes resulting to its formation
