Noun: * A species of coniferous tree, specifically a medium-sized larch (Larix), native to the Rocky Mountains of North America. It is a close relative of the Western Larch (Larix occidentalis). This tree is characterized by its deciduous needles that turn yellow and drop in autumn, and its preference for high-altitude, subalpine environments.

• Capitalization: The term is a scientific binomial name (genus and species). It is conventionally written in italics, with the genus name capitalized and the species name in lowercase: .
• Context: This term is primarily used in scientific, botanical, forestry, and ecological contexts. It is not commonly used in everyday conversation.
