    Description

    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 by tangential rows of fibers. Its porous are diffuse with moderately few, small, very long vessel elements and scalariform intervessel pitting. Vessels are solitaries with scalariform perforations having 20-40 bars. Rays are uniseriate and homocellular. P. costariceme shares many features with P. macranthum and Canella winterana.
