Codonopsis tubulosa ssp tubulosa
A tubular flowered twining climber similar to C. benthamii with a green corolla, slightly more yellow at the tips of the petals. The calyx lobes are much longer than on C. benthamii and the flower shape is slightly less waisted. The stems are dark red and leaves large and pointed with prominent pale veins on the underside.
Seeds and tuber shape are unknown as this is a new species for us.
