Wood Anatomy Of Caryophyllaceae: Ecological, Habital, Systematic, And Phylogenetic Implications, Sherwin Carlquist
Wood Anatomy Of Caryophyllaceae: Ecological, Habital, Systematic, And Phylogenetic Implications, Sherwin Carlquist
Aliso: A Journal of Systematic and Floristic Botany
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 primitive to specialized so great that origin close to one of the more specialized families of Chenopodiales, such as Chenopodiaceae or Amaranthaceae, is unlikely. Caryophyllaceae probably branched from the ordinal clade near the clade's base, as cladistic evidence suggests. Raylessness …
Wood And Bark Anatomy Of Ranunculaceae (Including Hydrastis) And Glaucidiaceae, Sherwin Carlquist
Wood And Bark Anatomy Of Ranunculaceae (Including Hydrastis) And Glaucidiaceae, Sherwin Carlquist
Aliso: A Journal of Systematic and Floristic Botany
Wood anatomy of 14 species of Clematis and one species each of Delphinium, Helleborus, Thalictrum, and Xanthorhiza (Ranunculaceae) is compared to that of Glaucidium palma tum (Glaucidiaceae) and Hydrastis canadensis (Ranunculaceae, or Hydrastidaceae of some authors). Clematis wood has features typical of wood of vines and lianas: wide (earlywood) vessels, abundant axial parenchyma (earlywood, some species), high vessel density, low proportion of fibrous tissue in wood, wide rays composed of thin-walled cells, and abrupt origin of multiseriate rays. Superimposed on these features are expressions indicative of xeromorphy in the species of cold or dry areas: numerous narrow latewood vessels, presence …
