We investigated the early floral development of the monotypic genus Amborella, the sister to all other extant angiosperms. Examination of vegetative shoot development revealed that Amborella possesses both decussate and alternate phyllotaxy; one may simply be a special case of the other as a reaction to meristem size and shape. The transition from bracts to tepals is gradual, making it difficult to determine exactly where a flower begins in this species. Although flowers of Amborella are… Expand

Floral Phyllotaxis and Floral Architecture in Calycanthaceae (Laurales)
TLDR
A comparative study of floral phyllotaxis of calycanthaceous fossil flowers, comprising species of all four genera of the family, found spiral floral phytotaxis is spiral according to the Fibonacci pattern for all species studied. Expand
Amborella trichopoda (Amborellaceae) and the evolutionary developmental origins of the angiosperm progamic phase.
TLDR
New data from Amborella and a review of fertilization biology of other early-divergent angiosperms show that an evolutionary transition from slow reproduction to rapid reproduction occurred early in angiosperm history. Expand
Floral Developmental Morphology of Persea americana (Avocado, Lauraceae): The Oddities of Male Organ Identity
A floral developmental series was determined for Persea americana (Lauraceae, avocado), and the floral morphology of this species was compared with available data for other members of Persea. We… Expand
Floral development of petaloid Alismatales as an insight into the origin of the trimerous Bauplan in monocot flowers
TLDR
The results indicate that the origin of the floral Bauplan, at least in petaloid Alismatales, is closely linked to the position of stamen pairs and the rate of petal development. Expand
PERIANTH DEVELOPMENT IN THE BASAL MONOCOT TRIGLOCHIN MARITIMA (JUNCAGINACEAE)
Basal monocots exhibit considerable variation in inflorescence and floral structure. In some cases, such as Triglochin maritima, it is not clear whether the lateral and terminal structures of the… Expand
Ancestral traits and specializations in the flowers of the basal grade of living angiosperms
TLDR
An updated review of floral morphology and its evolution in the basal ANITA grade of living angiosperms, Chloranthaceae, and Ceratophyllum, which concludes that phyllotaxis is complex whorled in Nymphaeales and spiral in Amborella and Austrobaileyales. Expand
Floral Development and Anatomy of Aextoxicon punctatum (Aextoxicaceae‐Berberidopsidales): An Enigmatic Tree at the Base of Core Eudicots
TLDR
Data indicate that Aextoxicon, together with Berberidopsidaceae, might represent a basal transitional lineage of basal to core eudicots and evidence that pentamerous flowers with a biseriate perianth evolved from progenitors with a comparable floral structure is provided. Expand
Reconstructing the ancestral angiosperm flower and its initial specializations.
TLDR
This work evaluates early floral evolution in angiosperms by parsimony optimization of morphological characters on phylogenetic trees derived from morphological and molecular data and indicates that the simple flowers of the newly recognized basal groups are reduced rather than primitively simple. Expand
Perianth Biology in the Basal Grade of Extant Angiosperms
TLDR
Perianth structure and behavior were studied comparatively in representatives of all families of the basalmost extant angiosperms (ANITA grade plus Chloranthaceae) and only in the latter groups are there genera with basally united tepals (Amborella, Cabomba, and Hedyosmum). Expand
Morphology of Hydatellaceae, an anomalous aquatic family recently recognized as an early-divergent angiosperm lineage.
TLDR
The family Hydatellaceae was recently reassigned to the early-divergent angiosperm order Nymphaeales rather than the monocot order Poales, and several hypotheses on the homologies of reproductive units in Hy datellaceae are explored. Expand

The Reproductive Structures of the Basal Angiosperm Amborella Trichopoda (Amborellaceae)

Evolution of Floral Structures in Basal Angiosperms
TLDR
The reconstructed patterns of evolution in the flowers of basal angiosperms indicate that the patterns of perianth and stamen phyllotaxis are usually, but not always, closely associated, and that floral characters are generally consistent with phylogenetic relationships inferred from molecular data.

Development of Inflorescences and Flowers in Buxaceae and the Problem of Perianth Interpretation
TLDR
In this investigation, development and structure of inflorescences and flowers of representatives of all buxaceous genera were studied comparatively to gain a better understanding of flower structure in Buxaceae and their relationships to basal eudicots. Expand
The population structure and floral biology of Amborella trichopoda (Amborellaceae)
TLDR
Floral size dimorphism reported for this species was confirmed by differences in floral biomass, and Structural studies indicate that the stigma is of the dry-type, and the pollinators probably visit female flowers because of the mimetic role of the staminodes. Expand
Floral structure and evolution of primitive angiosperms: Recent advances
TLDR
Valvate anthers have now been found in most larger subgroups of theMagnoliidae and lowerHamamelididae and in some Cretaceous fossils and problems with the comparison of paleoherb flowers with those ofGnetales are discussed. Expand
Cuticle evolution in Early Cretaceous Angiosperms from the Potomac Group of Virginia and Maryland
TLDR
The stratigraphic trend in cuticle types supports the concept that the subclass Magnoliidae includes the most primitive living angiosperms, but it also suggests that the uniformly paracytic stomatal pattern characteristic of Magnoliales may actually be derived from the variable condition found in Zone I leaves.

Developmental morphology and structural homology of corolla-androecium synorganization in the tribe Amorpheae (Fabaceae: Papilionoideae).
TLDR
It is concluded that the stemonozone of Dalea, Marina, and some species of Psorothamnus is not strictly homologous to either androecium or receptacle, but that it is the product of a modified androECial developmental program. Expand
