Rhynchospermum verticillatum: A
perennial that grows in hilly districts, with stems erecting
50-100cm in height and long rhizomes that crawl. Caudexes (stems)
stop growing at a point where two or four lateral branches will
diverge. 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 during flowering.
Flower heads, 4-5mm across, are put on the tops of short branchlets
and generally bloom, facing downward. Bloom time:
August-October. |
