Wood and Bark Anatomy of the New World Species of Ephedra

Wood, Bark, and Pith Anatomy of Old World Species of Ephedra and Summary for the Genus

Quantitative and qualitative data are presented for wood anatomy of 35 collections representing 22 Old World species of Ephedra; the survey of bark and pith anatomy is based on some of these species. Character-state ranges similar to those of the New World species are reported, although more numerous species show vessel absence in latewood. Little diminution in vessel diameter or density occurs...

Wood and Bark Anatomy of Degeneria

Wood anatomy of the recently described Degeneria roseiflora differs from that of D. vitiensis by possessing narrower vessels, much thicker-walled vessels and fiber-tracheids, abundant uniseriate rays, and greater numbers of ethereal oil cells in rays. Because both large and smaller wood samples of D. vitiensis were studied, ontogenetic changes in the wood are presented and separated from those ...

Wood and Bark Anatomy of Ranunculaceae (Including Hydrastis) and Glaucidiaceae

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, s...
