A voucher
herbarium specimen is a pressed plant deposited in a herbaria
for future reference. It supports research work and may be examined
to verify the identity of the plant used in a study.
Why is voucher material needed? The classification
of plants is transitional. Shifts in species alignments and
groupings are made as new evidence comes to light. Identifications
are subject to change. Vouchers specimens help cross-reference these
changes to previous research.
GETTING STARTED
Preplanning for the preparation of voucher specimens
is crucial. Arrangements should include:
* Targeting collection locations and date periods
to obtain useful specimens.
* Obtaining collection permits from appropriate agencies
(this can take months).
* Establishing official contact with government, herbarium and research
personnel in the area you will be working. This is required by law
in most countries.
