Alismatales are a key clade in monocot evolution, as they are sister to all other monocots,
excluding Acorales. However, phylogenetic relationships within the order are poorly …

Pollen and anther characters are potentially informative in higher-level systematics of
monocotyledons. Several characters of monocot pollen and anthers (tapetum type …

The pollen morphology of Butomaceae, Limnocharitaceae and Alismataceae, the three
families comprising the Alismatales, was studied using light and scanning electron …

Malpighiales are one of the least resolved of the major angiosperm orders; more
comparative data are needed to elucidate deep relationships and character evolution within …

Background and Aims Early developmental events in microsporogenesis are known to play
a role in pollen morphology: variation in cytokinesis type, cell wall formation, tetrad shape …

To evaluate hypotheses on pollen evolution in Annonaceae, we present a cladistic analysis,
using both palynological and non-palynological characters, and including other Magnoliales …

According to recent molecular phylogenetic data, the rare Australian endemic Maundia
triglochinoides does not form a clade with taxa traditionally classified as members of …

The remarkable diversity of pollen morphology in Annonaceae has attracted systematic
attention since the 1970s. Optimization of pollen characters on a molecular tree confirms that …

Phylogenetic analyses based on morphology place Anaxagorea and other taxa with
granular monosulcate pollen, as in other Magnoliales, at the base of Annonaceae. Taxa with …

The development and structure of the megagametophyte of Anarthria (Anarthriaceae),
Aphclia, and Centrolepis (Centrolepidaceae) are described. Anarthriaceae has …
