Abstract
Chrysochlamys is a genus of neotropical angiosperms distributed in wet and riparian forests from Bolivia to Mexico in altitudes from near sea-level to close to 3000 m. The wood anatomy of two species of the genus was investigated. Branches of mature stems were collected in a secondary wet forest in Colombian Northern Andes. Slides were obtained and visualized using light microscopy. Gelatinous fiber bands were found and described in C. colombiana and C. dependens. There was a higher amount of septate fibers in the latter. Average ray height and pigment deposit content in ray cells was greater in C. colombiana relative to C. dependens, but rays were commonly wider in the second one. The diversity of vessel-ray pit shapes in C. dependens is greater than in C. colombiana. In both cases rays are considered to be paedomorphic type I. Scanty to absent axial and apotracheal parenchyma was found for both species. We discuss the similarities and differences of the two species in order to establish diagnostic wood features. Also we include brief notes in comparative anatomy with other members of the Clusieaceae family, emphasizing in the incongruences found with previous reports for the genus. This is the first descriptive work in wood anatomy of C. colombiana and C. dependens.
