Three intercontinental disjunctions in , subfamily ,: evidence from chloroplast DNA,. All American representatives of the subfamily possess distinctive morphological features. This might be the result of Tertiary and Quaternary climatic oscillations leading to severe bottleneck situations in ancient N American populations.

Rapid radiation of North American desert genera of the ,: Evidence from restriction site mapping of radiation event caused by major climatic changes in the past. Poor phylogenetic resolution seems to reflect biological reality and not to be an experimental artifact. There is also evidence for accelerated morphological evolution under arid climatic conditions.

Phylogenetic relationships of the Lardizabalaceae and Sargentodoxaceae: Chloroplast and nuclear DNA’ . (., ., ., ., and .) characterized by laminar placentation, is well-supported as a monophyletic group. A subset of this clade consisting of three Asian genera (., ., and .) is also a well-supported monophyletic group.

Wood anatomy of ,: a summary, families can, however, be ranked from primitive to specialized in terms of vessel element length and “F/V ratio” (length of imperforate tracheary elements divided by length of vessel elements) as well as in terms of morphology of imperforate tracheary elements. . — especially the genus . — rank as

Sieve-element plastids, phloem proteins, and the evolution of the ,,iameter of the sieve-element plastids from stem phloem is with 1.62 μm rather large, both compared to other superorders and to the dicotyledon average. Among the five families recognized in the . (incl. .), . and . contain the largest average diameters (above 1.9 μm) while those of ., ., and . are a
