Rhynchospermum verticillatum: A
perennial that grows in hilly districts, with stems erecting
50-100cm in height and long rhizomes crawling. Caudexes (stems) stop
growing at a point where two or four lateral branches will divaricate. Leaves are 7-15cm long and 17-32mm wide, with sparse
dentitions on margins, sharp tips, bristles on both surfaces, and no
petioles. The lower part's leaves wither in the flowering time.
Flower heads, 4-5mm across, put themselves on the tops of short
branchlets and generally bloom, facing downward. Bloom time:
August-October. |
