Brown-ribbed Dandelion
Taraxacum pannulatum
Overview
The Brown-ribbed Dandelion (Taraxacum pannulatum) is a rare perennial herb distinguished by its distinctive brown-veined leaves and pale yellow flower heads that are smaller than those of common dandelions. This specialized dandelion species plays a crucial role in supporting endemic pollinators and contributes to the genetic diversity of alpine plant communities through its unique adaptations to harsh montane conditions.
The Brown-ribbed Dandelion faces severe threats primarily from habitat destruction and fragmentation due to agricultural expansion and urban development in its limited range. Climate change poses additional pressure through altered precipitation patterns and temperature shifts that affect its specialized alpine and subalpine habitat requirements.
Habitat
This species is restricted to rocky limestone outcrops and scree slopes at elevations between 2,200-3,100 meters, typically found in crevices and ledges with well-drained, alkaline soils. It thrives in areas with late-melting snow patches that provide consistent moisture during the brief growing season.
