Nepenthes Classification: Highland, Lowland, Intermediate Explained

Question: What elevation defines intermediate Nepenthes? Is 500–1300 m correct?

Answer: Terms are arbitrary guidelines. General consensus: 1000 m divides highland/lowland. Intermediate straddles that line. No strict agreement—we prefer elevation ranges. Examples: N. macfarlanei (1000–2000 m) called highland or intermediate; N. sanguinea similar elevation but called highland; N. truncata (0–2000 m) has both forms. We define intermediate as "grows in either highland or lowland conditions" (cool nights helpful but not required, or tolerant of cool nights). Use elevation data for precise guidance.

Good growing!
