Molecular phylogenetic analysis of uniovulate Euphorbiaceae (Euphorbiaceae sensu stricto) using plastid RBCL and TRNL-F DNA sequences
TL;DR: Parsimony and Bayesian analyses of plastid rbcL and trnL-F DNA sequence data of the pantropical family Euphorbiaceae sensu stricto (s.s.) show that two subfamilies, 14 tribes, and 10 genera were found to be para- or polyphyletic.

Support for an expanded family concept of Malvaceae within a recircumscribed order Malvales: a combined analysis of plastid atpB and rbcL DNA sequences
Clemens Bayer,Michael F. Fay,Anette Y. De Bruijn,Vincent Savolainen,Cynthia M. Morton,Klaus Kubitzki,William S. Alverson,Mark W. Chase +7 more
TL;DR: Sequence analyses of the plastid genes atp B and rbc L support an expanded order Malvales and propose to merge Sterculiaceae, Tiliaceae and Bombacaceae with Malvaceae and subdivide this enlarged family Malvoideae into nine subfamilies based on molecular, morphological, and biogeographical data.

Molecular phylogenetics of Melastomataceae and Memecylaceae: implications for character evolution.
G. Clausing,Susanne S. Renner +1 more
TL;DR: Parsimony and ML analyses of cpDNA sequences from the rbcL and ndhF genes and the rpl16 intron generate congruent topologies that place Memecylaceae as sister to Melastomataceae, implying, for example, that berries evolved from capsules minimally four times, stamen connectives went from dorsally enlarged to basal/ventrally enlarged, and loss of an endothecium preceded poricidal dehiscence.

The Study of Fossil Gymnosperms by Means of Cuticular Analysis
TL;DR: In this paper, the potential use of cuticles for the identification of gymnosperm remains, correlation of their dispersed organs, biostratigraphic, paleoecologic, and paleoclimatologic interpretations are briefly discussed.
