Phylogenetic relationships and character evolution analysis of Saxifragales using a supermatrix approach

American Journal of Botany, 2013
• Premise of the study: We sought novel evolutionary insights for the highly diverse Saxifragales by constructing a large phylogenetic tree encompassing 36.8% of the species‐level biodiversity.• Methods: We built a phylogenetic tree for 909 species of Saxifragales and used this hypothesis to examine character evolution for annual or perennial habit ...

Further Resolution of the Rapid Radiation of Saxifragales (Angiosperms, Eudicots) Supported by Mixed-Model Bayesian Analysis

Systematic Botany, 2004
Recent phylogenetic analyses of Saxifragales, based on DNA sequences of five plastid and nuclear ribosomal genes under parsimony and likelihood criteria, failed to resolve the branching order of the major lineages of the clade. This lack of resolution was attributed to the rapid radiation of Saxifragales.

The impact of extinct taxa on understanding the early evolution of Angiosperm clades: an example incorporating fossil reproductive structures of Saxifragales

Plant Systematics and Evolution, 2006
A cladistic analysis was performed including five Cretaceous and 31 extant taxa within Saxifragales using a combination of molecular sequence and morphological data in order to elucidate the utility of extinct taxa in illuminating saxifragalean evolution.

Stéréostructure de l'exine des Saxifragales: proposition d'une description logique et schématique

Bulletin De La Société Botanique De France, 1975
ResumeUne methodologie descriptive schematique est proposee pour la traduction des informations nombreuses apportees par les micrographies M.E.B. Elle devrait eviter une terminologie contestable, trop souvent illogique (description desordonnee), surchargee de paraphrases et limitee par les barrieres linguistiques.

A Review of the Fossil Record of the Genus Itea (Iteaceae, Saxifragales) with Comments on its Historical Biogeography

Botanical Review, The, 2013
Itea is a genus of about 20 species of trees and shrubs that are today native to southeastern North America, eastern Asia, and eastern Africa. In this paper, I review the fossil record of Itea, which is based on four types of fossils: diporate, psilate pollen attributed to Itea or the dispersed pollen genus Iteapollis; carpofossils representing fruits ...

From Fossils to Molecules: Phylogeny and the Core Eudicot Floral Groundplan in Hamamelidoideae (Hamamelidaceae, Saxifragales)

Systematic Botany, 2007
Most floral diversity in the core eudicots is based on a groundplan that includes among its most distinctive elements a bipartite perianth and pentamerous merosity combined with a bicarpellate gynoecium. To obtain insights into the origins of this groundplan, the evolution of its structural components in Hamamelidoideae (Hamamelidaceae, Saxifragales ...
