Abstract A cladistic resolution is presented for the origin of the angiosperms based on a parsimony analysis of 49 taxa of Magnoliidae. Hamamelidae and Alismatidae, with gymnospermous outgroup comparisons for the polarization of 104 characters. The Magnoliidae is recognized as a paraphyletic assemblage of nine orders: Calycanthales, Magnoliales, Laurales, Illiciales, Lactoridales. Ranunculales, Aristolochiales, Piperales and Nymphaeales. The Calycanthaceae and Idiospermaceae are segregated as… 
Ordinal and familial relationships of Ranunculid genera
A morphological-based cladistic analysis was conducted on 116 ingroup taxa and 5 outgroups coded for 109 characters and 192 apomorphic character states. Ranunculid genera are better organized as the
Flowers in Magnoliidae and the origin of flowers in other subclasses of the angiosperms. I. The relationships between flowers of Magnoliidae and Alismatidae
TLDR
Comparative ontogenetic studies reveal that the paired arrangement of stamens can be derived from the early stages of a spiral androecium following a perianth consisting of trimerous whorls.
Patterns of floral evolution in the early diversification of non-magnoliid dicotyledons (eudicots)
TLDR
Evidence from morphology and molecular sequence data indicates that extant Ranunculidae as well as “lower” Hamamelididae and several other families are basal in this group of dicotyledons, and cyclic floral architecture is probably basic for eudicots as a whole.
Morphological Phylogenetic Analysis of Living and Fossil Chloranthaceae
TLDR
A parsimony analysis was carried out using morphological data from 38 extant and six fossil species, and the resulting cladograms support the monophyly of the Chloranthaceae as well as the four extant genera Chloranthus, Sarcandra, Ascarina, and Hedyosmum.
Phylogenetic Analyses of Cretaceous Fossils Related to Chloranthaceae and their Evolutionary Implications
TLDR
Results imply that flowers became unisexual before losing the perianth, while bisexual flowers in Canrightiopsis, Sarcandra, and Chloranthus are secondarily derived from unisexual flowers.
Allonia decandra: Floral remains of the tribeHamamelideae (Hamamelidaceae) from Campanian strata of southeastern USA
TLDR
The occurrence of fossils assignable to Loropetalinae during the Campanian documents the existence of Hamamelidaceae with a level of floral organization and character evolution equivalent to that of extant genera, early in the evolutionary history of the family.
Gynoecium diversity and systematics of the Laurales
Carpel and ovule structure was comparatively studied in representatives of all eight families of the Laurales: Amborellaceae, Calycanthaceae, Chloranthaceae, Gomortegaceae,Hernandiaceae, Lauraceae,
The origin and diversification of angiosperms.
The angiosperms, one of five groups of extant seed plants, are the largest group of land plants. Despite their relatively recent origin, this clade is extremely diverse morphologically and
Hacia una filogenia de Aristolochia y sus congeneres neotropicales
TLDR
The two monospecific South American genera Euglypha and Holostylis resulted to be placed in crown clades, as the sister groups of Aristolochia subser.
Systematics, biogeography and conservation of Lactoridaceae
TLDR
Recommendation is that the lone species of Lactoris is placed as a monotypic order, Lactoridales, allied most closely to Aristolochiales, and also near Piperales, and genetic variation within and among populations as measured by isozymes and RAPDs is low.

The diversity of stamen structures and dehiscence patterns among Magnoliidae
TLDR
Finds point to the probability that valvate anthers were more common in primitive angiosperms than previously thought, and the counterforce to the opening valves is provided on the morphological and not on the histological level.

TLDR
A data matrix for a sample of the angiosperms with 61 characters for 49 taxa, mostly magnoliifloran and related families, is presented, illustrative of the great homoplasy in the available character information, and of how little actually is known about fundamental angiosperm interrelationships or phylogeny.
SYSTEMATIC ANATOMY OF THE LEAF EPIDERMIS IN THE MAGNOLIACEAE AND SOME RELATED FAMILIES
Summary Stomatal and other epidermal features suggest a close relationship among the Magnoliaceae, Eupomatiaceae, Degeneriaceae, and Himantandraceae, a somewhat more distant relationship of the
OBSERVATIONS ON PTYXIS, PHENOLOGY, AND TRICHOMES IN THE CYCADALES AND THEIR SYSTEMATIC IMPLICATIONS
TLDR
Ptyxis, phenology, and leaf trichomes are described for 43 species representing all ten genera in the Cycadales of which the family Boweniaceae D. nov. is described.
Comparative Pollen Morphology of the Madagascan Genera of Myristicaceae (Mauloutchia, Brochoneura, and Haematodendron)
TLDR
Pollen of all three genera of Madagascan Myristicaceae is studied and the distinctness of the frequently united genera Mauloutchia and Brochoneura is confirmed, as well as that of the recently described new genus Haematodendron.
Aspects of evolutionary differentiation of the Hamamelidaceae and the Lower Hamamelididae
TLDR
Three patterns of valvate anther dehiscence are recognized in the subfamily Hamamelidoideae (and the subclass Hamamelididae), which seem to be the remnants of a homogeneous group that originated before the Upper Cretaceous.
Sieve-element plastids, phloem protein, and evolution of flowering plants. III: Magnoliidae
TLDR
Two hundred sixty-three species of the Magnoliidae distributed over the main genera of all its families were investigated with the TEM for ultrastructural characters from their sieve elements to provide a putative phylogenetic arrangement of the families of Magnoliiflorae.
On the laterocytic stomatotype in angiosperms
TLDR
Investigation of the stomatal apparatus of 18 species of Hamamelidaceae showed that in addition to the anomocytic, paracytic, and encyclocytic stomatotypes previously known in the family, the laterocytic type is found in several genera (Dicoryphe, Exbucklandia, and others).
THE MORPHOLOGY OF THE MYRISTICACEAE. I. FLOWERS OF MYRISTICA FRAGRANS AND M. MALABARICA
Floral histology and vascular anatomy of Myristica fragrans Van Houtt. and M. mnalabarica Lam. have been investigated from ser'al sections and specimens cleared in chloro-lacto-phenol. The flowers
Are the angiosperms primitively vesselless
TLDR
The hypothesis that angiosperms are primitively vesselless was tested in the context of a cladistic analysis of selected families of the Magnoliidae, Ra- nunculidae, and Hamamelididae and it is suggested that the xylem of these genera is paedomorphic.
