Saussurea obvallata
Saussurea obvallata, commonly known as Brahmakamal, is a species of flowering plant in the Asteraceae. It is native to the Alpine meadows of the Himalayas, in India, Bhutan, Nepal, Pakistan and southwest China at altitudes of 3,700 to 4,600 m.
Description
Saussurea obvallata is a perennial growing to 0.3 m. The flowers are hermaphrodite and are pollinated by insects. Flowers bloom in mid-monsoon amongst the rocks and grasses of the hillside at an altitudinal range of 3700–4600 m. Flower heads are purple, hidden from view in layers of yellowish-green papery bracts, which provide protection from the cold mountain environment. The flowers can be seen from July through September, after which the above-ground portions of the plant die back, becoming visible again in April.The Saussurea genus are named for alpine scientist Horace Bénédict de Saussure, while the specific epithet obvallata is derived from obvallatus, meaning "surrounded by wall;" in this case the flower's involucriform bracts.
