A collection of dried and pressed plants arranged according to an accepted system of classification and available for study or reference is known as herbarium (plural, herbaria).

About 165,000 herbarium specimens of both flowering and non-flowering plants have been housed at KATH.

The herbarium specimens are under digitization process using herb scanner (Epson Expression 10,000XL) and camera (Nikon D810).

A total of 152,796 digitized specimens are presently available online in plantdatabase.kath.gov.np.
