  1. Wood anatomy of the neotropical Sapotaceae. V, Calocarpum

    Calocarpum, long maintained as a distinct taxon, is now generally considered as a synonym of Pouteria. The wood anatomy is quite different from Pouteria (sensu stricto) and the author is of the opinion that reduction to synonomy is not justified. The anatomical evidence supports the treatment of Calocarpum by the monographer Charles Baehni.

  2. Wood anatomy of the neotropical Sapotaceae. VII, Chrysophyllum

    In the neotropics, the genus Chrysophyllum consists of C. cainito and a number of species which have recently been assigned to the genus Cynodendron. Many taxonomists have not accepted the new genus Cynodendron and this is supported by the present study of the wood anatomy. In this restricted sense, Chrysophyllum consists of a group of closely related species that are...

  3. Wood anatomy of the neotropical Sapotaceae. VI, Chloroluma

    The old genus Chloroluma has been reinstated to generic status after having been in synonomy under Chrysophyllum for many years. The description is based on the type species C. gonocarpa which is characterized by: Its clear yellow wood; pores in radial-echelon arrangement; rhombic, two-sized, and microcrystals frequent in the axial parenchyma and wood rays; colored...

  4. Wood anatomy of the neotropical Sapotaceae. IV, Achrouteria

    Achrouteria pomifera Eyma, the sole representative of the genus for almost 40 years, is distinguished from the world Sapotaceae by the very large silica particles which occur in the wood rays. Anatomically, two groups (species) may be distinguished on the basis of vessel member length and parenchyma seriation. A second species, A. durifructa described in 1974, differs...

  5. Comparative wood anatomy of root and stem of Citharexylum myrianthum (Verbenaceae)

    Root and stem wood anatomy of C. myrianthum (Verbenaceae) from a semideciduous seasonal forest in Botucatu municipality (22º52’20”S and 48º26’37”W), São Paulo state, Brazil, were studied. Growth increments demarcated by semi-ring porosity and marginal bands of axial parenchyma were observed in the wood of both root and stem. Many qualitative features...

  6. Wood anatomy of Pleodendron costaricense (Canellaceae) from Southern Pacific, Costa Rica

    Pleodendron costaricense N. Zamora, Hammel & R. Aguilar (Canellaceae) is an endemic species from the southern Pacific region of Costa Rica. It is rare and is considered to be a living fossil. The wood of P. costaricense has high density (0.92 Kg/cm3, air dry) with little distinction between heartwood and sapwood. The growth rings are marked...

  8. Changes in tracheid and ray traits in fire scars of North American conifers and their ecophysiological implications

    Fire scars have been widely used as proxies for the reconstruction of fire history; however, little is known about the impact of fire injury on wood anatomy. This study investigates changes in tracheid and ray traits in fire scars of Douglas fir (Pseudotsuga menziesii), western larch (Larix occidentalis) and ponderosa pine (
