Recent attempts to address the long-debated 'origin'of the angiosperms depend on a
phylogenetic framework derived from a matrix of taxa versus characters; most assume that …

Developmental genetic pathways involved in flower formation in model plants such as
Arabidopsis and maize enable us to identify genes, gene families, and gene networks that …

Am. J. Bot. 91: 1726–1741. Friis EM, PR Crane, and KP Pedersen. 1997. Fossil history of …

Floral morphology is key for understanding floral evolution and plant identification. Floral
diagrams are two-dimensional representations of flowers that replace extensive descriptions …

Increasingly robust understanding of angiosperm phylogeny allows more secure
reconstruction of the flower in the most recent common ancestor of extant angiosperms and …

The construction of classifications, as well as the understanding of biological diversity,
depends upon a careful comparison of attributes of the organisms studied (Stuessy, 1990). It …

Eudicots and their currently recognized major subclades are characterized as to floral
structure (including some “embryological” features) based on ca. 3000 original publications …

Merism in flowers is the result of a combination of a whorled phyllotaxis, the proportion of
relative sizes of floral organs and flower meristem, and pressures from external organs …

Sequence data of the trnL group I intron, the petD group II intron, the trnL-F and petB-D
spacers, and the rapidly evolving matK gene were analysed from all families of the basal …

An increasingly robust phylogenetic framework based on molecular and fossil data clarifies
the sequence of evolutionary innovations in land plants. Oogamy and cellular novelties …
