ID requested for Trillium cf. chloropetalum

Gastil,

T. angustipetalum occurs on the coast, but generally south of the Redwoods.  It
is found in San Luis Obiso and Santa Barbara Counties, while Redwoods don’t
really extend south of Monterey County.  T. chloropetalum on the other hand
inhabits the coastal counties where Redwoods are common.  The CalFlora maps go
by county; they’re very coarse grained.   A plant reported at the southern edge
of a long North-South County and another at the northern border doesn’t imply
that they overlap.  I doubt that you’d find T. angustipetalum in any of the
Redwood parks – except – T. kurabayshii is considered a form of T.
angustifolium, and it is found in Humboldt County north, along with the tallest
Redwoods.
