Abstract
Helictotrichon sempervirens
(Poaceae), a common ornamental grass cultivated in rock gardens, described from southern France, is discussed and typified. The name is originally based on the basionym
Avena sempervirens
. The designation of a lectotype is based on an analysis of original material stored in the GRM herbarium, alongside the critical examination of diagnostic morphological characters, label data, protologue information, and Villars's botanical work. We also discuss the nomenclatural complexity associated with the names and distinctive morphological characters of
H. sempervirens
.
The typification of the Linnaean name
Achillea impatiens
(Asteraceae) is discussed. Examination of the protologue and associated original material revealed that both the illustration published by Gmelin in “Flora Sibirica” and a specimen preserved in the Linnaean Herbarium (Herb. Linn. No. 1017.9, LINN) constitute...

The history of Sprengel’s Jaegeria bellidioides has been shrouded in nomenclatural uncertainty, with different authors ascribing it to morphologically distinct taxa. Through the examination of protologs, relevant type material, and digital collections of historic herbaria, we clarify the source of this confusion and pr...

A new species of Leucheria endemic to the Patagonian Andes in northern Neuquén, Argentina, is reported. Leucheria melorum is characterized by its cushion-like growth habit composed of dense woolly rosettes, rhizomes covered by persistent old leaves, and capitula with white to pink flower corollas. The species inhabits...

Based on an integrative taxonomic approach (morphological and molecular analysis of ITS and matK), Liparis phifarelisiae, a new species endemic to Réunion Island is described. The first formal record of Liparis perrieri in the Mascarene archipelago is also documented. Liparis phifarelisiae is distinguished by its tetra...

Tirpitzia laotica (Linaceae) is described and illustrated from limestone karst in Vang Vieng District, central Laos, representing the first record of the genus Tirpitzia in the country. The new species is distinguished from previously known species in the genus by a combination of strikingly long inflorescences up to 1...

The occurrence of Reichardia gaditana (Willk.) Samp. is here reported and documented for the first time as a new record to native costal flora of Tunisia following botanical surveys carried out during mainly the last decade within the centre-eastern part of the country. General characteristics as well as original photo...
