genus Trillium
Member of
trillium family (family Melanthiaceae)
monocots (class Liliopsida)
flowering plants (subphylum Angiospermae)
There are no other wild species of this genus in the bay area.
Key features:
If the stamen and ovary colors differ, some on iNaturalist claim that the ovary color determines the species, but Jerpson says the anther color determines, and FNA simply says that a range of intergrade hybrids exist. The direction of anther dehiscence may be the correct identifier, but I can’t tell the difference in photos.
