Herbarium is a collection of dried plant specimens identified, mounted and arranged using a standard system of classification. It is the data associated with the herbarium specimen that determines its value and relates to the following: Characters of all parts of plant, which is represented in dried condition; information on locality, habitat, use, etc. noted by the collector and given on the herbarium label ; notes and annotations made on the specimen sheet during study by later taxonomists.

  • Build-up reference collection of economically important taxa, both indigenous and exotic, as herbarium specimens, seeds and photographs.
  • Hold supplementary collection of seeds, economic products/ fruits samples, drawings/ illustrations and photographic records.
  • Maintain working collection of herbarium specimens of wild, weedy taxa, cultivars, primitive landraces, obsolete cultivars etc. representing crop genepool.
  • Support plant genetic resources (PGR) programme by making available diversity in the form of herbarium specimens for use by a wide range of users including PGR workers.
  • Establish and maintain links/liaison with other herbaria and genebanks.
  • Organise and provide teaching and training for build-up, and to maintain and utilize herbarium resources in PGR study
  1. Identification of plant species: Herbarium specimens are the source of morphological characters by which the plant may be identified in the field and distinguished from related species. These also help to delimit the range of variation within a species which can be used to pinpoint areas of cross-compatibility and occurrence of natural hybrids and introgressed forms.
  2. Locating species/ diversity distribution and phytogeography: Taxa represented as herbarium specimens from diverse habitats over its distributional range, provide authentic records of their occurrence and distribution. Diversity represented from natural populations provide source material for working out distribution patterns, habitat preferences, etc. for mapping diversity, working out naturalized and weedy taxa, predicting areas of occurrence and changes therein due to climate change and habitat loss, and delineating taxa that are endemic, rare or threatened.
  3. Documenting information on taxa: Herbarium specimens and associated data noted as label information are source material for revalidating information on uses on local/ regional levels which aid in pinpointing incipient domesticates and wild useful plants. Data on ethnobotanical importance, folk value etc. too can be obtained from herbarium labels.
  4. Vouchers of PGR diversity: Representative herbarium specimens of taxa that have been collected and conserved in the field genebank, or as seeds or propagules viz. landraces of crops, wild species, etc. and material from experimental study provide records of material that can be used for reference and study.
  5. Source material for taxonomic and experimental study: Herbarium specimens provide the basic material for systematic studies on crop genepools and crop-weed complexes and morphometric studies on native taxa which can be further substantiated by field-based study.
  6. Herbarium-based samples for experimental study: Seeds, leaf tissue and other plant parts can be used for systematic study viz. phytochemical and biochemical study of proteins and secondary metabolites and as source material for DNA; in selected cases such as extinct species, these may be the only available source of such material for systematic study.

Plant material for processing as herbarium specimens is collected directly from the field during the period when flowering and fruit formation occur. Efforts are made to represent all parts of the plant. During exploration trips when mature fruits and seeds are available, usually leaves and flowers may not be available; specimens are prepared for such taxa from plants raised in pot-culture or experimental fields.

All plant parts are represented in a herbarium specimen to the extent possible. Information on locality, habitat, use, etc. noted by the collector is recorded on the herbarium label. Special procedures are adopted relating to processing of large-sized plants and plant parts, fleshy plants, delicate and fragile plants and selected taxa that are prone to damage by pests during storage.
