(3049) Proposal to reject the name Camphorosma glabra (Camphorata glabra) (Chenopodiaceae)
No full textIn continuing our efforts to clarify the Linnean species of Camphorosma (Freitag & Iamonico in Phytotaxa 202: 235–236. 2015; Iamonico & Freitag in Taxon 64: 816–821. 2015, 73: 313–314. 2024; Iamonico & al. in Taxon 72: 929–930. 2023) here we propose the rejection of Camphorosma glabra L
Lectotypification of the name Polycnemum majus (Amaranthaceae s.str.)
No full textAs part of a revision of the genus Polycnemum Linnaeus (1753: 35) in Europe we here present a nomenclatural study of the untypified name Polycnemum majus A. Braun ex Bogenhard (1841: 151–152). This study is also related to a joint nomenclatural investigation of the Linnaean names of Camphorosma Linnaeus (1753: 122), where we detected that most original material of C. acuta Linnaeus (1753: 122) agrees with P. majus. That matter and a corresponding formal proposal to conserve P. majus so as to maintain that name will be published elsewhere

Nomenclatural notes on the genus Pteranthus (Caryophyllaceae) with lectotypifications of the names Camphorosma pteranthus and Pteranthus trigynus, and comments on Forsskål’s seeds sent from Egypt
No full textThe nomenclatural history of the genus Pteranthus (Caryophyllaceae) is reviewed. Original material of Camphorosma pteranthus and Pteranthus dichotomus came from a single gathering made by Forsskål in the desert outside Cairo, Egypt, in March 1762. The original material of C. pteranthus was grown from seed collected with the herbarium material of P. dichotomus. Pteranthus dichotomus is therefore considered a replacement name for C. pteranthus and lectotypified with the same specimen, no. 165.5 LINN (right-hand plant). A supporting epitype is chosen from flowering herbarium material of the same gathering held at C (as florets are required to distinguish between varieties). The name P. trigynus is lectotypified by a specimen preserved at MA and the varietal status of P. dichotomus var. trigynus is confirmed

Compilation of high-density crusts in snow from various locations in Dronning Maud Land (East Antarctica) and northern Greenland
No full textThin crusts in snow with high density contribute to firn stratigraphy and can have significant impact on firn ventilation as well as on remotely inferred properties like accumulation rate or surface mass balance. From snow profiles measured by means of microfocus X-ray computer tomography we created a unique dataset showing the spatial distribution of crusts in snow on the East Antarctic Plateau as well as in northern Greenland including a measure for their local variability. With this method, we are able to find also weak and oblique crusts, to count their frequency of occurrence and to measure the high-resolution density
