Bean-Trefoil
adenocarpus viscosus
Adenocarpus viscosus, commonly known as the Bean-Trefoil or Sticky Adenocarpus, is a remarkable high-altitude shrub endemic to the Canary Islands. Dominating the subalpine volcanic landscapes of Tenerife and La Palma, this hardy member of the pea family paints the rocky slopes with bursts of bright yellow flowers during its blooming season. Its ability to thrive in harsh, nutrient-poor volcanic soils makes it a cornerstone of its unique ecosystem. It is especially famous for the sticky, glandular hairs that coat its flower calyces and seed pods, a feature that earns it its specific epithet 'viscosus.' As a nitrogen-fixing plant, it plays a vital role in enriching the arid soils of places like Teide National Park, supporting a web of endemic insects and wildlife in an otherwise unforgiving environment.
生息地: Found in dry, rocky, high-altitude subalpine zones and volcanic slopes, typically between 1,500 and 2,500 meters above sea level.
外見
This densely branched, evergreen shrub typically grows between 0.5 and 2 meters tall. It features small, tightly clustered, dark green trifoliate leaves that are slightly hairy. During late spring and early summer, it erupts into dense terminal racemes of vibrant, golden-yellow, pea-like flowers. A key identifying trait is the presence of sticky, reddish-brown glandular hairs that prominently cover the flower bases (calyces) and the developing legume pods, giving the plant a distinctive tacky feel and a dotted appearance upon close inspection.

おもしろい事実
Despite being buried under snow in the winter and enduring blazing sun in the summer, this hardy shrub thrives in some of the highest elevations of the Canary Islands.
It is a foundational pioneer species in the extreme environment of Mount Teide, helping to build soil so other endemic plants can take root.
The species name 'viscosus' refers to the sticky, glue-like substance produced by glands on its seed pods, which easily stick to hikers' clothing.
Traditional beekeepers transport their hives up the mountainsides when the Bean-Trefoil blooms to produce a highly prized, single-flower mountain honey known as 'Miel de Retama del Teide'.
特殊能力
能力
Nitrogen Fixation
Symbiotically partners with soil bacteria in its root nodules to convert atmospheric nitrogen into usable nutrients, allowing it to thrive in poor volcanic soils.
能力
Glandular Defense
Produces a sticky, viscous secretion on its reproductive parts that deters crawling insect herbivores and protects developing seeds.
能力
Extreme Climate Tolerance
Highly adapted to survive the intense solar radiation, strong winds, and extreme temperature fluctuations of subalpine volcanic calderas.
