Abstract

: The Carpathian stenoendemic species Erysimum hungaricum Zapał. (Brassicaceae) had not been observed at its only known locality in the Maramureş Mts in Romania for more than 80 years. Research from June 2018 has confirmed its presence on the southern slope of Mt. Lostun Mic (1595 m). Compared to the past, the number of micro-locati o ns was reduced to a single one of approximately 200 m 2 . In the remaining population, approximately 100 flowering individuals, we made a phytocoenological relevé and determined the chemical properties of the soil (pH H2O = 6.46; pH KCl = 6.2; carbonate content = 8.0 g.kg -1 ; nitrogen content = 10.99 g.kg -1 ; phosphorus content = 19.57 mg.kg -1 ). In the plant community, succession occurs from the original Festucetum saxatilis Domin 1933 to a tall-herb vegetation of the order Adenostyletalia alliariae Br.-Bl. 1931 and a growth of Picea abies . The presence of the species in different vegetation units and the comparison of older and actual soil characteristics point to its wider tolerance of the characteristics of the site. Thus, the causes of the extraordinary rarity of the species are not yet clear. Based on the IUCN sozological evaluation, the species was categorised as Critically Endangered (CR) according to criteria B2ab(ii,iv).

匈牙利丹参。(芸苔科)还生长在罗马尼亚吗?

喀尔巴阡特有种匈牙利赤藓。(芸苔科)在罗马尼亚maramureekts唯一已知的地点没有被观察到超过80年。从2018年6月开始的研究证实，它在洛斯顿山南坡(1595米)存在，与过去相比，微位置的数量减少到一个约200平方米。在剩余种群中，我们对大约100个开花个体进行了植物群落学分析，并测定了土壤的化学性质(pH H2O = 6.46;pH KCl = 6.2;碳酸盐含量= 8.0 g.kg -1;含氮量= 10.99 g.kg -1;磷含量= 19.57毫克。Kg -1)。在植物群落中，从原始的沙羊草(Festucetum saxatilis Domin 1933)演替到高草本植物(Adenostyletalia alliariae Br.-Bl)。1931年，云杉的生长。不同植被单元中物种的存在以及对旧土壤和实际土壤特征的比较表明，它对场地特征的容忍度更大。因此，该物种异常稀有的原因尚不清楚。根据国际自然保护联盟(IUCN)的生态学评价，根据B2ab(ii,iv)标准将其列为极度濒危物种。

期刊介绍： Contributii Botanice is an international, peer-reviewed journal publishing scientifically sound papers in the fields of Plant Systematics, Phytosociology, Plant Physiology and Morphology, Plant Ecology, Population Ecology, Ecosystem Ecology, Phytogeography, Phytopathology, Microbiology, Paleobotany, Plant Conservation and Cell/Molecular Plant Biology. Papers of mostly taxonomic nature or focussed on floristics and phytosociology will only be considered if they exceed the pure descriptive approach and have relevance interpreting patterns in the above mentioned plant sciences.
