I have photos of two different plants here which I think are both arisaema but one may be pinellia. The first I have two quite tall plants of. The flower part is fused to the leaf and well below the leaf. I am wondering if this is arisaema dracontium. (photos 1 and 2)
The second seems to be spreading around, so far not aggressively but seemingly by seeds because in different areas. On some of the plants the flower plant extends above the leaf and it is not completely fused to the stem. These are shorter. Are they pinellia pedatisecta or something else? (photos 3 and 4)
Please help me sort these out.
