  Dr. Antal Waisbecker (1835–1916) was a Hungarian physician and the most prominent botanist of Vas county (West Hungary) at the turn of the 19–20^th century. He contributed with important floristic data for the botanical monography of Vas county, authored by Vince Borbás. He processed the pteridophytes of Vas county and cormophytes in the surroundings of Kőszeg. Antal Waisbecker was an expert in the knowledge of sedges too. He discovered and described the Carex fritschii. Remarkable amount of herbarium specimens collected by Waisbecker are deposited at the Savaria Museum (Szombathely, SAMU) and Hungarian Natural History Museum (Budapest, BP).

  Two alien species from the Rubiaceae family were recorded as new for Hungary in 2016. Phuopsis stylosa is a rarely used garden plant in Europe, originally occurs in south-west Asia. A small escaped and established stand was found in Csákánydoroszló village in Vas County (West Hungary). Also a small group of Galium murale was discovered in Budapest-Keleti Railway Station (Central Hungary). This species is originated from the Mediterranean and probably spreads by rail transport. Both species are represented in their habitats by small populations therefore their invasiveness can only be evaluated after several years' monitoring.

  This article summarizes the recent occurrences of taxa of the C. brutia complex in Hungary. Formerly, C. hamulata was known from Hungary based on a specimen of uncertain origin from Vas County. The first confirmed record of the species date back to 2014, since then it has been found from from a total of 4 localities in streams in Western Transdanubia and along the Danube. The first detec­tion of C. brutia subsp. brutia was in 2016 in the Kunkápolnás marsh of the Hortobágy region, and since then the subspecies has been spreading in the area. The subsp. naftolsky was found in 2024 in a terres­trial form in a saltwater marsh in the Dél-Tiszántúl region. While C. hamulata is probably a native member of the Hungarian flora, the two subspecies of C. brutia may have colonised more recently, probably introduced by birds. Their colonisation may be related to the ongoing climate change, which has resulted in the introduction of plants from the Mediterranean region, often by natural means.
