How many type specimens can be stored in old lesser-known herbaria with turbulent histories? - A case study reveals their importance in taxonomy and biodiversity research.

Many herbarium sets in Europe are still being catalogued and it is likely that many old-type collections are yet to be discovered. This research has the potential to facilitate the study of the biodiversity of many regions, especially regions for which collections are extremely scarce. This has been confirmed by a case study using (Juncaceae) examining the turbulent history of botanical collections at the WRSL herbarium and the evaluation of its importance to the study of taxonomy and biodiversity since 1821.

Juncus quartinianus (Juncaceae, sect. Ozophyllum): A Neglected Species from the Horn of Africa and Its Re-Description Based on Morphological SEM Studies.

Juncus quartinianus (Juncaceae sect. Ozophyllum) was described by Richard in 1851 from Ethiopia. Some authors have treated this species as a synonym of J.

First Report of 'Candidatus Phytoplasma asteris' Associated with "Witches'-Brooms" on Jointleaf Rush (Juncus articulatus) in Poland.

Juncus articulatus L. (Juncaceae) is a species of rush occurring in Eurasia, Canada, and the United States. In 2013, symptoms of "witches'-brooms," similar to those associated with phytoplasma infection in other plants, were observed on jointleaf rush plants in Lower Silesia (southwest Poland), with some pests feeding on them.
