Archaefructaceae is proposed as a new basal angiosperm family of herbaceous aquatic plants. This family consists of the fossilsArchaefructus liaoningensis and A.sinensis sp. nov. Complete plants from roots to fertile shoots are known. Their age is a minimum of 124.6 million years from the Yixian Formation, Liaoning, China. They are a sister clade to all angiosperms when their characters are included in a combined three-gene molecular and morphological analysis. Their reproductive axes lack… 

A Whole-Plant Monocot from the Early Cretaceous

Morphological and phylogenetic analyses revealed that Sinoherba is an herbaceous monocot taxon, and underscores the great diversity of angiosperms in the Lower Cretaceous Yixian Formation.

An early infructescence Hyrcantha decussata (comb. nov.) from the Yixian Formation in northeastern China

This report is a detailed account of this early flowering plant and recognizes earlier reports of similar fossils from Russia and China, and presents entire plants, including roots, stems, and branches terminating in fruits.

A New Angiosperm Genus from the Lower Cretaceous Yixian Formation, Western Liaoning, China

The abundant fossils of early angiosperms found in the Yixian Formation (125 Ma, Early Cretaceous) have demonstrated unexpectedly high diversity and various reproductive strategies, and thus have

Lingyuanfructus: The First Gymno-angiosperm

Distinct from gymnosperms with naked ovules, angiosperms are defined and characterized by their enclosed ovules. According to Darwinism, angiosperms should be derived from their ancestors that have

Botany: New home for tiny aquatics

The Hydatellaceae are small aquatic plants living modest lives away from the limelight, and conventionally assumed to be monocotyledonous flowering plants related to grasses, but have been subjected to the latest molecular techniques, and they turn out to be close relatives of basal angiosperms such as water lilies, increasing their importance immensely.

Hydatellaceae identified as a new branch near the base of the angiosperm phylogenetic tree

It is shown that Hydatellaceae, a small family of dwarf aquatics that were formerly interpreted as monocots, are instead a highly modified and previously unrecognized ancient lineage of angiosperms, indicating that water lilies are part of a larger lineage that evolved more extreme and diverse modifications for life in an aquatic habitat than previously recognized.

Monocotyledon fossil leaf from the Early Cretaceous of India

Reports of the angiosperm macrofossils from the Early Cretaceous sediments of India are relatively poor, with only one report from the Krishna-Godavari Basin. The present study documents a

A Dichocarpum‐like Angiosperm from the Early Cretaceous of China

The Yixian Formation (the Early Cretaceous) of China has yielded a diverse group of early angiosperms, revealing the charm of angiosperms from the formation is far from finishing. Here we report a



In search of the first flower: A jurassic angiosperm, archaefructus, from northeast china

Angiosperm fruiting axes discovered from the Upper Jurassic of China have primitive characters and characters not considered primitive, and the leaf-like structures subtending each axis define them as flowers.

Molecules, morphology, fossils, and the relationship of angiosperms and Gnetales.

Even if molecular data resolve the relationships among living seed plant groups, understanding of the origin of angiosperm organs will require integration of fossil taxa, necessarily using morphology.

Fossil evidence of water lilies (Nymphaeales) in the Early Cretaceous

The history of the water lilies (Nymphaeales) is extended back to the Early Cretaceous and into the oldest fossil assemblages that contain unequivocal angiosperm stamens and carpels, adding to the growing congruence between results from molecular-based analyses of relationships among angiosperms and the palaeobotanical record.

A Reevaluation of Seed Plant Phylogeny

The results support the placement of the cycads as the sister group of a monophyletic group that includes several fossil «seed ferns» as well as extant Ginkgo, conifers, gnetopsids, and angiosperms.

Angiosperm phylogeny inferred from 18S rDNA, rbcL, and atpB sequences

A phylogenetic analysis of a combined data set for 560 angiosperms and seven outgroups based on three genes, 18S rDNA, rbcL, and atpB representing a total of 4733 bp is presented, resulting in the most highly resolved and strongly supported topology yet obtained for angiosPerms.

Biostratigraphy of new pterosaurs from China

Pterosaurs are represented in China by five genera and some isolated bones ranging in age from the Middle Jurassic to the Late Cretaceous period. Four of these genera belong to the derived

The Anther: Form, Function and Phylogeny

This work focuses on the development of Stamen development in legumes with emphasis on porate stamens of Cassieae, and investigates adaptations for animal pollination and diversity of endothecial patterns in the angiosperms.

Angiosperm Origins: Morphological and Ecological Aspects

This text contains a description of the morphological grades and their linking forms; a discussion of seed plant evolution; an overview of early angiosperms and their environments; and a n analysis


These results support many aspects of the strobilar‐flower hypothesis for the origin of the angiosperms, as well as the plesiomorphic character states of woody shrubs with simple, pinnatelyveined leaves.

Diversity and evolutionary biology of tropical flowers

This book discusses the biology of selected systematic groups in the tropics of flower evolution and the role of pollinators in this process.
