A normal trillium and an infected trillium. Note the leaf-like carpels of the infected trillium. A trillium with two whorls of petals. Note also the white-tipped sepals. Oone of the stamens has transformed into a petal on this trillium.
Reproductive whorls are completely absent.
This individual has two sets of ruffled green-striped petals. Note also that there are only four stamens and only two carpels. This is a 'numbers mutant' which may be the product of damage to the floral meristem, although the green stripes in the petals suggest that a mycoplasm infection might also be the cause. There are only two leaves, sepals, and petals. The reproductive whorls are unaffected.
