@RNGherb @Nat_SCA. Mitigating the potential contamination risk incurred in sampling herbarium specimens for phytolith reference collection. Preparing Cacti Herbarium Sheets. The ReCAP: Stories from California Herbaria. When you first learn about stacks of plant specimens housed in herbaria, it is tempting to envision these collections as quiet, inanimate storage spaces.

The ReCAP: Stories from California Herbaria

You can imagine the smells of paper and dust, the quiet hum of florescent lights, and imposing rows of tightly shut cabinets. Indeed, many California herbaria are currently fated to this state with the shelter-at-home order still in place, but this was not always the case. ​ Herbaria can be bustling hubs of creating, tending, discovering, and learning, and without constant care and curation, years of hard-earned data can be imperiled. Even when students learn from home and researchers keep to their desks, herbaria still require resources and attention.

Designing a state-of-the-art taxonomic research workstation - The Plant Press

As botanists develop more knowledge the science of taxonomy becomes increasingly complex. Between 1753 and 2016, the number of known plant species has risen from about 6,000 to 390,000, an average increase of nearly 1,500 species each year. Over 2,000 new species were discovered in 2015. The number of specimens held globally in herbaria has also increased.

There are now over 3,000 herbaria around the world holding nearly 400 million specimens. Applications in Plant Sciences. The instructions below use a sample iNaturalist data set (see Appendix S1) and an associated blank template for generating herbarium labels (Appendix S2) similar to that shown in Fig. 1B.

Such material may have passed through several owners before coming to rest in a particular collection, in movements that are not always documented. An author’s original labels (where these survive) and other handwritten sources can be useful in verifying the status of a particular lot. In museum collections, original labels have usually been supplemented with those written by successive curators and researchers. Paperclip crimes against specimens. Sad. #CurationCrimes…

Bringing Joseph Banks into the 21st Century

He was an avid botanist and his collection included a significant collection of insects. His collection was originally left to Banks’ librarian Robert Brown, but to the British Museum thereafter. Banks was an influential man who was president of the Royal Society 1778 to his death in 1820. This enabled him to continue supporting expeditions and forging networks bringing together specimens from the Atlantic, Indian and Pacific worlds. Banks entomology collection.

» Unearthing History in the Herbarium

Part of my job in the Herbarium of the NYBG is processing plant collections researchers have stored over the years. In general, we only mount plants that have been identified to species. That process can be quick if there is currently a specialist–we send the person a duplicate of a plant collection, and they send us the plant’s name once it has been identified. However, identifying plants to specific species can take much longer if there is no one currently specializing in a certain family or genus.

Tape: A Field Book Tale of Terror - Field Book Project

It was a dark and stormy night… Actually, it was a lovely summer day when we received a researcher request for a few volumes from the field notes of Frederick Vernon Coville, a botanist known, in part, for his participation in the Death Valley Expedition. Ordinarily, researcher requests are quite straight forward, but this was no ordinary set of volumes. In a past repair effort, someone had used that most dreaded of materials, pressure sensitive tape!

Herbarium Management

A Plant Morgue An herbarium is a collection of pressed, dried, and labeled plants (and may also include other types of collections including wood or seeds). Perhaps a less morbid analogy is that an herbarium is a reference library of plants. It is generally agreed that Luca Ghini (1490-1556), Professor of Botany at the University of Bologna, prepared the first herbarium specimens as we recognize them today. His students, Cibo, Turner, Aldrovandi and Cesalpino also made herbaria, some of which still exist (John McNeill, 1997; Taxacom Discussion). Another contender for the oldest herbarium specimen is an olive branch removed from King Tut’s tomb (Craig Hilton-Taylor, 1997; Taxacom discussion). II. Monetary Value.

III. Making herbarium specimens at Kew. Kew’s herbarium houses approximately 7.5 million specimens of plants, which are used by Kew scientists and visitors to the herbarium on a daily basis – and are occasionally sent to other institutions for study. There are specimens in the collection that are 250 years old, and include material collected by the likes of Charles Darwin and some of Kew’s previous directors including W.J. Hooker and J.D. Hooker. In this blog post we explain how we mount (display on paper) specimens to ensure their availability for future scientists. RHS-Guide-to-making-herbarium-specimens.

Thermo-lignum-warmair-treatment-method - Thermo Lignum. Using only naturally occurring elements, air and water, sound biological principles and established laws of physics, all insects inhabiting organic materials will die at any life-cycle stage when exposed to our Thermo Lignum® WARMAIR treatment method. The absence of any chemicals or noxious gases during the process allows immediate reuse of the items upon completion of the treatment, without risk of harm to your health, the object, or the environment. The Thermo Lignum® process essentially targets the susceptibility of insects to elevated temperatures of around 48-55°C dependent on the species.

From a conservation point of view the key to using warm air to kill insects is to maintain the moisture content of the material at a constant level during the heating, holding and cooling phases.

How does a plant specimen get turned into an herbarium sheet, ready for a Museum collection? In order for plants to be carefully cataloged and preserved so that they can be studied well into the future, they first have to be dried and pressed. The herbarium sheet.
