Genus Olsynium

Tropical: Equatorial and tropical zones defined by consistent year-round warmth. This encompasses the wet tropics, seasonally dry tropics, and cooler high-altitude montane tropics.
Subtropical: Warm transition zones between tropical and temperate regions, typically characterized by mild, largely frost-free winters. (Note: WCVP groups dry-summer Mediterranean climates within this broader biome).
Temperate: Mid-latitude climates defined by distinct seasonal shifts, including a true winter season where regular frosts and plant dormancy are expected.
Arid: Moisture-deficient climates—including true deserts and dry shrublands—where evaporation exceeds precipitation, requiring severe drought adaptations.
Cold: High-latitude subarctic or high-altitude subalpine climates defined by severe winters, prolonged freezing, and highly restricted growing seasons.
