The use and misuse of herbarium specimens in evaluating plant extinction risks [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2018
Herbarium specimens provide verifiable and citable evidence of the occurrence of particular plants at particular points in space and time, and are vital resources for assessing extinction risk in the tropics, where plant diversity and threats to plants are greatest.

Detection and annotation of plant organs from digitised herbarium scans using deep learning [PDF]

Biodiversity Data Journal, 2020
As herbarium specimens are increasingly becoming digitised and accessible in online repositories, advanced computer vision techniques are being used to extract information from them. The presence of certain plant organs on herbarium sheets is useful information in various scientific contexts and automatic recognition of these organs will help mobilise ...

A machine learning approach for cross-domain plant identification using herbarium specimens

Neural Computing and Applications, 2022
AbstractThe preservation of plant specimens in herbaria has been carried out for centuries in efforts to study and confirm plant taxa. With the increasing collection of herbaria made available digitally, it is practical to use herbarium specimens for the automation of plant identification.

A pragmatic and prudent consensus on the resurrection of extinct plant species using herbarium specimens

TAXON, 2021
AbstractHerbaria may represent remarkable sources of viable diaspores for recovering lost genetic variation and extinct plant species, but the application of rewilding extinct species using these collections has not been explored in detail. De‐extinction in plants may be achieved by germinating viable diaspores or culturing tissues preserved in ...

Medicinal plant uses and names from the herbarium of Francesc Bolòs (1773–1844) [PDF]

Journal of Ethnopharmacology, 2017
Ethnobotany takes into account past uses to be projected into the present and future. Most current ethnobotanical research is focused, especially in industrialised countries, on obtaining information of plant uses from elderly people. Historical ethnobotany is less cultivated, although papers have demonstrated its interest.

USING HERBARIUM DATA TO INCREASE THE LIKELIHOOD OF FINDING FERTILE PLANTS IN THE FIELD

Edinburgh Journal of Botany, 2021
The Phenological Predictability Index (PPI) is an algorithm incorporated into Brahms, one of the most widely used herbarium database management systems. PPI uses herbarium specimen data to calculate the probability of the occurrence of various phenological events in the field.

Potential of Herbariomics for Studying Repetitive DNA in Angiosperms

Frontiers in Ecology and Evolution, 2018
Repetitive DNA has an important role in angiosperm genomes and is relevant to our understanding of genome size variation, polyploidisation and genome dynamics more broadly.

Ecological data in support of an analysis of Guinea-Bissau׳s medicinal flora

Data in Brief, 2016
This dataset presents an annotated list of medicinal plants used by local communities in Guinea-Bissau (West Africa), in a total of 218 species. Data was gathered by means of herbarium and bibliographic research, as well as fieldwork.

First records of powdery mildew fungi (Erysiphales) on medicinal plants in Taiwan

Botanical Studies, 2021
Background Production of medicinal plants in Taiwan is not only hampered by international market competition, but also lack of knowledge of their pathogens, such as powdery mildew fungi (Erysiphales, Ascomycota).
