Wood Anatomy of Crossosomatales: Patterns of Wood Evolution with Relation to Phylogeny and Ecology

Wood Anatomy of Crossosomatales: Patterns of Wood Evolution with Relation to Phylogeny and Ecology

The seven families hypothesized by Sosa and Chase to comprise Crossosomatales possess relatively long vessel elements with scalariform perforation plates and scalariform to opposite vessel-ray pitting; tracheids; diffuse axial parenchyma; and heterogeneous rays. These and other primitive character states do not indicate relationships, but they do not offer any evidence against the idea that Cro...

Wood Anatomy of Bruniaceae: Correlations with Ecology, Phylogeny, Organography

-Wood of Bruniaceae is very primitive according to widelyaccepted criteria. Vessels are relatively long, with scalariform perforation plates having numerous bars, fully or vestigially bordered. Many aberrations in disposition of bars and perforations in perforation plates are present, and no species has exclusively normal perforation plates. Lateral wall pitting of vessels, both intervascular a...

Wood Anatomy of Fouquieriaceae in Relation to Habit, Ecology, and Systematics; Nature of Meristems in Wood and Bark

Qualitative and quantitative data are presented for wood of all species of Fouquieriaceae, the samples selected so as to cover important variables with respect to organography and age . Wood contains fibertracheids (plus a few vasicentric tracheids) . Diffuse axial parenchyma is mostly grouped as diffusein-aggregates or diffuse clusters (new term), with transitions to pervasive axial parenchyma...
