Asplenium adulterinum Milde is one of the rarest and most threatened representatives of the Aspleniaceae family in the Carpathians. Botanical literature mentioned the ladder spleenwort in many localities in South-Eastern Carpathians in the past, but during the last decades the species has not been collected and deposited in public herbaria by any botanist. All existing herbarium material in Romanian herbaria (including Asplenium trichomanes and A. trichomanes-ramosum) was revised and all available information from botanical literature was critically compiled in order to clarify the distribution of Asplenium adulterinum in the South-Eastern Carpathians. After almost 80 years since the first mention of the species in the Carpathians, this paper reports the recent identification of Asplenium adulterinum in three new locations in South-Eastern Carpathians (Ţesna Valley, Vânturătoarea Waterfall and Şugăului Gorges).

Maramureşului Mountains Nature Park is widely known as one of the last wilderness areas in Europe and also represents a real oasis for naturalists eager to explore the flora and fauna of this special land not very researched. During a botanical trip in the area of Farcău Peak (on 19 July 2014) the authors of this paper found three very rare species (all 3 threatened, included in Romanian Red Book of Vascular Plants): Trifolium lupinaster L., Heracleum carpaticum Porcius and Ranunculus thora L. Based on field studies, analyses of herbarium material and literature data, the authors managed to record the occurrence of Trifolium lupinaster, Heracleum carpaticum and Ranunculus thora in the Romanian Carpathians and determined the threatened status of species according to criteria and categories of IUCN.

Draba simonkaiana Jáv. is a critically endangered, Southern Carpathian endemic species, distributed only in Parâng, Retezat and Cozia Mountains. As an European endemic, and restricted to a single European country, D. simonkaiana is treated as a “species of European concern”. Although of great international significance, the distribution of Draba simonkaiana is slightly known, without any georeferenced records on GBIF. Based on field studies, analyses of herbarium material and literature data, the authors managed to record the occurrence of D. simonkaiana in Southern Carpathians and determined the threatened status according to criteria and categories of IUCN. Unfortunately, the species has not been found in locus classicus (Badea Hill) but the authors have discovered two new localities (in Parâng Mountains) of this important endemic species.
