Wood Anatomy of Caryophyllaceae: Ecological, Habital, Systematic, and Phylogenetic Implications

Wood of Caryophyllaceae is more diverse than has been appreciated. Imperforate tracheary elements may be tracheids, fiber-tracheids, or libriform fibers. Rays may be uniseriate only, multiseriate only, or absent. Roots of some species (and sterns of a few of those same genera) have vascular tissue produced by successive cambia. The diversity in wood anatomy character states shows a range from p...

Wood Anatomy of Portulacaceae and Hectorellaceae: Ecological, Habital, and Systematic Implications

A B STR ACT Qualitative and quantitative wood data are g iven for 13 species of 10 ge nera of Portulacaceae (secondary xylem from additional species of Anacampseros and Lewisia were studied but not quantitatively analyzed). Most Portulacaceae show modifications that can be related to the succulent habit, including wide, tall rays mostly composed of thin-wall ed cells; tota l or partial substitu...

Wood Anatomy of Stilbaceae and Retziaceae: Ecological and Systematic Implications

Wood anatomy of ten species in five genera of the Cape Province (South Africa) family Stilbaceae is reported in quantitative and qualitative terms. Wood anatomy for stem, root, and lignotuber is reported for the monotypic Cape genus Retzia. Stilbaceae and Retziaceae are alike in wood anatomy but differ from Verbenaceae by having scalariform perforation plates with few and wide-bordered bars (si...

Wood Anatomy of Berberidaceae: Ecological and Phylogenetic Considerations

Qualitative and quantitative data are presented for 21 collections of Berberis and one each of Epimedium, Jeffersonia, and Nandina. Most species of Berberis have large numbers of narrow vessels ~ixed with vasicentric tracheids. Scalariform perforation plates are reported here only for Epimedium, m wh1ch they are occasional. Berberidaceae have living fibers (Berberis), fiber-tracheids plus livin...
