Hoary Pterocephalus
pterocephalus lasiospermus
The Hoary Pterocephalus (Pterocephalus lasiospermus), locally known as 'rosalillo de cumbre' in the Canary Islands, is a resilient subalpine shrub endemic to the high-altitude volcanic terrains of Tenerife. Forming dense, silvery-green cushions, this fascinating plant is uniquely adapted to survive the intense sunlight, extreme winds, and freezing temperatures of Mount Teide's subalpine slopes. During the late spring and summer, it bursts into a spectacular display of pale lavender-pink flowers, transforming the austere volcanic landscape into a vibrant sea of pastel color.
生息地: Found in high-altitude subalpine scrublands and volcanic pumice plains, primarily between 1,800 and 2,600 meters elevation.
外見
This plant grows as a low, rounded shrub usually between 30 and 100 centimeters in height. Its most identifying characteristic is its dense, woolly covering of fine, white-gray hairs on its leaves and stems, giving it a distinct frosted or 'hoary' appearance. The leaves are soft, lance-shaped, and arranged in opposite pairs. In summer, it produces flat-topped, head-like flower clusters (capitula) colored in shades of pale pink to lavender, which eventually turn into fluffy, feathery, globe-shaped seed heads.

おもしろい事実
Because of its high-altitude environment, it acts as a crucial pioneer species, slowly breaking down volcanic minerals to help form fertile soil for other organisms.
It is a master of extreme environments, surviving freezing winter temperatures of down to -10 degrees Celsius and scorching, arid summer days on the active volcano.
The genus name Pterocephalus derives from the Greek words for 'feather' and 'head', referencing the fluffy, feather-like appearance of its seed clusters.
特殊能力
能力
Solar Shielding Pubescence
The dense layer of silvery-white hairs reflects harsh high-altitude ultraviolet rays and reduces water loss by trapping moisture close to the leaf surface.
能力
Volcanic Soil Anchoring
An extensive and deep root system allows the plant to anchor securely in loose, shifting volcanic ash and pumice while tapping into deep-seated moisture.
能力
Feathery Seed Parachutes
Its seeds are equipped with a feathery pappus, enabling them to catch alpine wind currents and disperse across rugged volcanic terrains.
