What are the morphological characteristics of this plant?

Incarvillea mairei has large, opposite, ovate leaves that are typically covered in soft, velvety hairs and long-tubular, bright orange-to-red flowers that emerge from upright spikes. The foliage is dense and lush, often providing a thick green base for the striking floral displays. These blossoms feature a prominent elongated corolla tube that tapers at the base and flares into wide lobes at the mouth. The stems are sturdy and erect, supporting the heavy weight of the blooming inflorescences throughout the growing season. As the plant matures, the flowers are arranged in a terminal raceme that rises significantly above the basal leaf rosette.

What is the geographical distribution of this plant?

This plant is endemic to the mountainous regions of central and southwestern China, specifically within the provinces of Yunnan and Sichuan. It thrives in high-altitude habitats where the terrain is typically rugged and rocky. These populations are often found in montane forests or shrublands at elevations ranging from several hundred to several thousand meters. The specific environmental conditions of these subtropical highland zones dictate its limited natural range. Consequently, its distribution is restricted to localized pockets within these specific mountain ranges.
