This dataset contains the digitized treatments in Plazi based on the original journal article Kaya, Ömer Faruk, Ertekin, Alaattin Selçuk (2025): An emended description for Rosularia haussknechtii (Boiss. & Reuter) A. Berger (Crassulaceae) from Southeastern Anatolia. Adansonia (3) 47 (18): 319-326, DOI: 10.5252/adansonia2025v47a18, URL: sciencepress.mnhn.fr/sites/default/files/articles/pdf/adansonia2025v47a18.pdf ABSTRACT Rosularia haussknechtii s.str. is an enigmatic endemic taxon only spread in Southeastern Anatolia.

Since the description of this species has been made only on herbarium specimens and from herbarium and live samples of R. pseudohaussknechtii Niederle incorrectly, unfortunately, it contains many deficiencies and mistakes. With this study, the only known type locality of R. haussknechtii s.str. was collected for the first time since 1865, and a new different locality was also found. Based on the live specimens from these different populations, the description of the species was emended.
