Flowers evolved in many steps, probably starting long before flowering plants (angiophytes)
originated. Certain parts of flowers are conservative and have not changed much during …

Although they are relative latecomers on the evolutionary scene, having emerged only 135?
170 million years ago, angiosperms—or flowering plants—are the most diverse and species …

We report a series of phylogenetic analyses of selected taxa from several presumably
closely related groups of angiosperm families, ie, Apocynaceae/Asclepiadaceae …

A new classification of Ericaceae is presented based on phylogenetic analyses of nuclear
and chloroplast DNA sequence data, morphology, anatomy, and embryology. Eight …

Phylogenetic interrelationships in the enlarged order Ericales were investigated by jackknife
analysis of a combination of DNA sequences from the plastid genes rbcL, ndhF, atpB, and …

Epacrids, a group of southern hemisphere plants formerly considered members of the
separate family Epacridaceae, are in fact most closely allied to the Vaccinioid tribe …

Why do unrelated organisms sometimes appear almost identical in details of the anatomy,

The phylogenetic structure of the tricolpate clade (or eudicots) is presented through a survey
of their major subclades, each of which is briefly characterized. The tricolpate clade was first …

Phylonyms is an implementation of PhyloCode, which is a set of principles, rules, and
