Cirsium congestissimum is a perennial herb of 1-1.5m in
height that inhabits high-altitude grasslands. Its stems are erect
and branching on the upper portions. With sharp prickles on the
margins, the on-stem leaves are of alternate phyllotaxis, oblong in
shape, measuring approximately 20cm in length, cleft to halfway.
Flower heads, around 2cm in height, with no peduncles, come out
densely on branch tips; the involucral bracts significantly bend
backward. Radical leaves are gone during flowering. Bloom time:
September-October. |
