MICROWAVE DRYING OF HERBARIUM SPECIMENS
TAXON, 1985SummaryThe authors propose the use of a microwave oven as a new rapid procedure for herbarium specimen drying. A comparison between the new method and the usual procedure is presented and discussed with regard to external appearance and morphological characteristics.

PREPARATION OF OPUNTIA HERBARIUM SPECIMENS
Haseltonia, 2007Abstract We present a best-practice method for preparing high-quality Opuntia herbarium specimens, from collection methods to storage. A botanical press having wide, thick, wooden boards is used for cladode drying. A layer consisting of corrugated cardboard, absorbent paper, newspaper, and a thin wood laminate is placed between each cladode.

On herbarium specimen images and artificial intelligence
New PhytologistSummary Digitized herbarium specimens are increasingly used to train artificial intelligence (AI) models in plant identification and other botanical applications. The abundant specimen images available in public repositories are especially amenable to AI. For instance, digitized herbarium sheets are relatively standardized – generally

1994
Old, soft tissues from plants and fungi may be derived from many sources, including fossil beds (Golenberg et al. 1990; Soltis et al. 1992) and sites of human or animal habitation (Rogers and Bendich 1985), but by far the most voluminous sources of these tissues are dried herbarium collections.

THE HERBARIUM PRESERVATION OF CONIFER SPECIMENS
TAXON, 1979SummaryThe adequate preservation of conifer specimens for the herbarium poses major problems concerned with the disintegration of material on drying. A new effective general method of treatment, which for the first time enables preservation to be achieved without disintegration, is described, and a schedule of treatment recommended.

DNA Extraction from Herbarium Specimens
2013With the expansion of molecular techniques, the historical collections have become widely used. Studying plant DNA using modern molecular techniques such as DNA sequencing plays an important role in understanding evolutionary relationships, identification through DNA barcoding, conservation status, and many other aspects of plant biology.
