Entwicklungsgeschichtliche Untersuchungen am Androeceum der Alismatales
�sterreichische Botanische Zeitschrift, 19731. Die Androeceen vonEchinodorus macrophyllus, E. intermedius, Alisma plantago-aquatica undSagittaria lancifolia stimmen in ihrer fruhen Entwicklung weitgehend uberein: Es werden zunachst sechs Stamina ausgegliedert, wobei sich jeweils eine Anlage beiderseits der Petalen befindet. 2.

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.

Monocots are remarkably homogeneous in sharing a common trimerous pentacyclic floral Bauplan. A major factor affecting monocot evolution is the unique origin of the clade from basal angiosperms. The origin of the floral Bauplan of monocots remains controversial, as no immediate sister groups with similar structure can be identified among basal ...

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.

Phylogeny of the Alismatales (Monocotyledons) and the relationship of
AbstractA phylogenetic analysis of the early branching lineages of the monocotyledons is performed using data from two plastid genes (rbcL and matK), five mitochondrial genes (atp1, ccmB, cob, mttB and nad5) and morphology. The complete matrix includes 93 terminals representing Acorus, the 14 families currently recognized within Alismatales, and ...

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.

Seagrasses are the only higher plants living in fully marine environments; they play a significant role in coastal ecosystems. Seagrasses inhabit the coastal shelves of all continents except Antarctica and can grow in depths of up to 90 m. Because of their eminent ecological importance, innumerous studies have been dedicated to seagrasses and their ...
