The northeastern American native A. triphyllum is best known
by the common name Jack-in-the-Pulpit.  Extremely variable,
numerous names and subspecies have been described
based on spathe coloration and form.  However, I
have found that single populations are remarkably variable,
therefore haven't given much notice to subspecific rankings.

Notice in this very dark form, that the spadix is dark purplish
brown (sometimes it is white), and there are 10-12 white
stripes that connect at the top of the spathe.  Typically in this
species, the top of the spathe curls over, and you can only
peek inside if you get on your belly or if the spathe is lifted
as shown.  The number and pattern of stripes is variable.
