We describe a new species of Blechnum from Mato Grosso, Brazil: rivulorum sp. nov. This was discovered as result visits to the herbaria BM, K, P, PR, and S, part Reflora Project, by first author. also indicate its position in phylogeny. Additionally, we confirm occurrence meridense Klotzsch Brazil provide an updated key all country.

Background: Mexico is a megadiverse country with an elevated diversity of species vascular plants. A comprehensive Flora that includes all the plants distributed in does not yet exist. Electronic Floras have demonstrated value compendium based on existing knowledge and published Floras, checklists revisions.
 Questions: What best approach for publishing Mexico? resources are needed to crea...

There is much excitement across a broad range of biological disciplines over the prospect using deep learning and similar modern statistical methods to label research data. The extensive time, effort, cost required for humans dataset drastically limits type amount data that can be reasonably utilized, currently major bottleneck application datasets such as specimen imagery, video audio recordin...

The application of DNA sequencing technology to the study of ancient DNA has enabled the reconstruction of past epidemics from genomes of historically important plant-associated microbes. Recently, the genome sequences of the potato late blight pathogen Phytophthora infestans were analyzed from 19th century herbarium specimens. These herbarium samples originated from infected potatoes collected...

Botanists estimate that 80 to 90% of existing plant species have already been described and it is expected that most undescribed species are rare or narrow endemic ones. Here we map the geographical distribution of Gymnanthes boticario, a species described in 2010, and show that the species is not only widespread, but was well-collected in the Caatinga semiarid vegetation prior to its descripti...

While conducting field inventories in South Cameroon, we collected two specimens of a new species that we considered to belong to the genus Angraecopsis. Afterwards, a careful examination of specimens housed at main herbaria, along with the nomenclatural types, allows us to place it in Distylodon, a monotypic genus previously known from East Africa. Distylodon sonkeanum Droissart, Stévart & P.J...
