Contribution to the embryology of Potamogeton L. (Alismatales: Potamogetonaceae)
Aquatic Botany, 2010Potamogetonaceae currently comprises four genera, including Potamogeton, a near cosmopolitan genus of about 100 species. The historical circumscription of this family is controversial, resulting in fragmentary information on the morphology and anatomy of its genera.

Pollen Evolution in the Early‐Divergent Monocot Order Alismatales
International Journal of Plant Sciences, 2010Alismatales 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.

CONDUPLICATE AND SPECIALIZED CARPELS IN THE ALISMATALES
American Journal of Botany, 1976Carpel 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.

a b s t r a c t The floral developmental patterns and carpel morphologies of Potamogeton illinoensis Morong, P. poly- gonus Cham. et Schltdl and P. pusillus L. were investigated under light (LM) and scanning electron microscopes (SEM) to identify potential characteristics for taxonomic studies.

A phylogeny and biogeographic analysis for the Cape-Pondweed family Aponogetonaceae (Alismatales)
Molecular Phylogenetics and Evolution, 2015The 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.

Floral organogenesis of Echinodorus amazonicus Rataj and floral construction of the Alismatales
Botanical Journal of the Linnean Society, 1978The primary trimerous pattern of the flower of Echinodorus amazonicus Rataj is clearly exhibited in the earliest developmental stages. After the inception of three sepals, theree alternisepalous petal-stamen complexes arise, each of which, at successively higher levels of the primordia, consists of a petal, a pair of stamens, and a single stamen.

Endosperm development in the Araceae (Alismatales) and evolution of developmental modes in monocots
Journal of Plant Research, 2010The 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.
