#steppe
- Alfold — The geographical name (borrowed from the Hungarian Alföld) designating the Great Hungarian Plain, a vast lowland region covering the hydrographic basins of the Tisza and Middle Danube, extending partially into western Romania. Geographically, the term describes a fertile steppe zone.
- Eastern pasqueflower — A scientific synonymous name for Pulsatilla patens, a perennial herbaceous plant in the family Ranunculaceae, widely distributed across the cold and temperate regions of Europe, Asia, and North America. It is famous as an early prairie or steppe wildflower, developing densely pubescent stems and large, erect, chalice-shaped flowers colored in shades from pale blue-violet to purple, often opening before the leaves fully emerge.
- Pre-steppe — An ecological and phytogeographical transitional zone situated between a forested or more humid environment and the steppe proper, characterized by mixed vegetation. In landscape ecology, this ecotone plays a critical role in soil stabilization and biodiversity conservation.
- Arithmometer — The first industrial mechanical calculating machine capable of performing the four fundamental arithmetic operations (addition, subtraction, multiplication, and division), patented in 1820 by the Frenchman Thomas de Colmar. This robust device, based on stepped drums with teeth of variable lengths, dominated administrative and banking offices worldwide for nearly a century, representing the technological grandfather of modern desktop calculators.
