archaeophyta

The observed plant species were divided into three groups: apophyta (the original species growing before human settlement), archaeophyta (plants characteristic of the villages in the Middle Ages, before the year 1500) and neophyta (plant species penetrating to settlements in the last 100 years) (Pysek, 1989).[…]The frequency of indicated ecological groups of plants (apophyta, archaeophyta and neophyta) in villages depends on climatic conditions and anthropic pressure.

In Poland there are some significant collections of old segetal (“weed”) species, the biggest in situ and ex situ collections of archaeophyta are run by Institue of Plant Breeding and Aclimatization at Radzików.[…]Among 58 taxa protected ex situ by Kostrzyca FGB will be 30 species protected by the National Law of the Republic of Poland, 10 species endemic or subendemic to Poland (mainly Sudeten Mts. endemics, found only in the SW Poland and NE Czech Republic and also a few Tatra Mts. endemics), 20 relic species (both glacial relics from mires and alpine meadows and xerothermic relics typical for steppes), 5 species of archaeophyta (ancient weeds, nowadays threatened due to progress in agriculture and land abandonment) and 6 species with unique biology (carnivorous, parasitic, pirophytic etc.).
