CONDUPLICATE AND SPECIALIZED CARPELS IN THE ALISMATALES

American Journal of Botany, 1976
Carpel closure and stigmatic localization in the Alismatales have accompanied decreases in carpel size and numbers of ovules per carpel and increases in carpel numbers per flower. The most specialized carpels are uniovulate and indehiscent and occur acyclically in great numbers in each flower, with strong trends toward monoecism and even dioecism.

Pollen Evolution in the Early‐Divergent Monocot Order Alismatales

International Journal of Plant Sciences, 2010
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 resolved, prompting the need for a reevaluation of pollen and tapetum characters, which have proved useful in other monocot groups, such as lilioids.

A phylogeny and biogeographic analysis for the Cape-Pondweed family Aponogetonaceae (Alismatales)

Molecular Phylogenetics and Evolution, 2015
The monocot family Aponogetonaceae (Alismatales) consists only of Aponogeton, with 57 species occurring in Africa, Madagascar, India and Sri Lanka, Southeast Asia and Australia. Earlier studies inferred a Madagascan or Australian origin for the genus.

Endosperm development in the Araceae (Alismatales) and evolution of developmental modes in monocots

Journal of Plant Research, 2010
The Araceae, a basal-most family of Alismatales that basally diverged subsequent to Acorales in monocot phylogeny, are known to have diverse modes of endosperm development: nuclear, helobial, and cellular. However, the occurrence of nuclear and helobial endosperm development has long been debated.

Phylogenetic studies of the core Alismatales inferred from morphology and rbcL sequences

Progress in Natural Science: Materials International, 2009
The phylogeny of Alismatales remains an area of deep uncertainty, with different arrangements being found in studies that examined various subsets of genes and taxa. Herein we conducted separate and combined analyses of 103 morphological characters and 52 rbcL sequences to explore the controversial phylogenies of the families.
