Nonrandom collecting practices may bias conclusions drawn from analyses of herbarium records. Recent efforts to fully digitize and mobilize regional floras online offer a timely opportunity to assess commonalities and differences in herbarium sampling biases. We determined spatial, temporal, trait, phylogenetic, and collector biases in c. 5 million herbarium records, representing three of the m...

Microloxia herbaria (Hübner, [1813]) and Scopula luridata (Zeller, 1847) are reported for the first time from Maltese Islands. Distribution habits of adult larvae included. A name is proposed these new records.

A nomenclatural revision of fifteen taxa of Xyris (Xyridaceae) described by L.A. Nilsson (1892) is presented as part of a taxonomic revision of the genus in Brazil. All the protologues and type collections of these taxa were studied. The type collections were examined in the respective herbarium collections where they are preserved and complemented by images available on herbarium websites and ...

Australia is rich in orchid flora with over 1000 native species currently recorded. A significant proportion of Australia’s terrestrial orchids are critically endangered, endangered or threatened. Threats to many orchid species include habitat destruction, degradation and fragmentation from increased urbanisation, overgrazing, altered fire regimes and unfortunately, excessive collecting by orch...

Did the banana, yam and taro arrive in Australia at the hands of Europeans or come across the Torres Strait 2000 years before? Reviewing the evidence from herbaria histories and anthropology, the authors propose a ‘hierarchy of hypotheses’ and consider a still earlier option, that these food plants were potentially grown in Australia at least 8000 years ago, while it was still joined to New Gui...

Here, we describe Trifolium absconditum sp. nov., a new species of the T. amabile complex from South America. It differs from other Peruvian Trifolia of the complex by having smaller stipules, leaves, inflorescences, and floral pieces. A key for Peruvian species of the complex is presented, and typifications for them are made when necessary and material is available in Peruvian herbaria. Thus, ...
