Established in 1977, the section is one of the oldest section of National Herbarium and Plant Laboratories (NHPL), has so far studied the wood anatomy of more than 135 plants species of the country. It continues to serve the Department of Forests for identifying species from the wood samples it confiscates quite often. The section is publishing a timber identification manual shortly. Anatomical manual of important timbers of Nepal Vol –I is already published and lab work is going on for further volumes. Now, there are more than 500 wood samples and ~ 2700 permanent slides of different woody plants at ‘KATH’ Xylarium. This section also provides wood identification services to District forest offices, traders, farmers, researchers and students.
The study on internal structure of wood helps the species in identification, qualitative and quantitative analysis of wood and fibers.To develop Wood Anatomy as a new tool and identify the problem of burning issue i.e 'Climate Change' in some extent, Anatomy section has started the study of Dendrochronology (Study of tree rings over time) and its other related fields as dendroecology, forest distrubances etc. from the fiscal year 2071-72 (2014-2015).
