Myristicineae, a new suborder within Magnoliales

Taxon, 2003
Abstract Myristicaceae are sister group to the remaining five families of Magnoliales, which make up the suborder Magnoliineae. Both with regard to morphological and DNA sequence data, Myristicaceae have diverged substantially from Magnoliineae, whereas at the same time monophyly of Magnoliales is conclusive. This relationship between

Pollen Diversity and Evolution in Myristicaceae (Magnoliales)

International Journal of Plant Sciences, 2003
Myristicaceae consist of 21 genera and nearly 500 species of lowland rainforest trees with a pantropical distribution. This article presents new scanning electron microscopy observations on pollen of 13 genera, including all Asian genera, which had previously received very little attention from palynologists.

Cuticular studies of magnoliales

Proceedings of the Indian Academy of Sciences - Section A Part 3 Mathematical Sciences, 1939
In the present work the question of the position of the Magnoliales from the point of view of their epidermal features has been taken up. This is rather a new line of inquiry. Florin’s criteria,viz., the haplocheile and syndetocheile types of stomatal development have been made use of.

Early Floral Development and Nature of the Calyptra in Eupomatiaceae (Magnoliales)

International Journal of Plant Sciences, 2003
Early floral development in Eupomatia bennettii and Eupomatia laurina was studied with scanning electron microscopy and serial microtomy to focus on initiation and development of the calyptra and initiation and phyllotaxis of the floral organs. Phyllomes preceding the calyptra are distichous or spirodistichous in arrangement.

A Compound Ovary with Open Carpels in Winteraceae (Magnoliales): Evolutionary Implications

Science, 1977
"Bubbia" perrieri , a primitive angiosperm collected once in 1909 in northwestern Madagascar, differs from all other members of its genus and family (Winteraceae) in its bicarpellate, unilocular ovary. Moreover, its inflorescences are terminal, and its development is partially sympodial.

�ber die Karpelle verschiedener Magnoliales. I

�sterreichische Botanische Zeitschrift, 1966
Die Karpelle vonIllicium — es sind jene vonI. anisatum, floridanum undsimonsii untersucht worden — sind eindeutig peltat gebaut. Die einzige Samenanlage entspringt der rudimentaren, mit der Blutenachse verwachsenen ventralen Schlauchwand, was aus ihrer Bundelversorgung sehr klar hervorgeht. Die Anordnung der Bundel in denIllicium-Karpellen ist ubrigens

�ber die Karpelle verschiedener Magnoliales III.Schisandra (Schisandraceae)

�sterreichische Botanische Zeitschrift, 1966
Die Karpelle vonSchisandra sind sehr deutlich peltat-schlauchformig gebaut, ihr kurzer Ventralspalt ist allseitig von einem einheitlichen Narbensaum umgeben. Entsprechend den beiden lateral inserierten Samenanlagen bleiben die beiden Randbundel auch im Schlauchteil gesondert; sie vereinigen sich jedoch bei der untersuchten Art,Schisandra grandiflora ...

Cloning and Sequence Determination of the ChloroplastpsbAgene inMagnolia pyramidata(Magnoliales; Magnoliaceae)

DNA Sequence, 1998
The full length gene encoding the D1 protein of photosynthesis (psbA) has been cloned and sequenced from Magnolia pyramidata (Magnoliaceae). Despite considerable investigation into psbA structure and function in many algal lineages and a few agricultural plants, there has been little effort invested toward characterizing a broader range of plant psbA ...
