Arisaema triphyllum - dark form
Photo by Mark
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 white (sometimes
it is dark brown or purplish-brown), and that 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.
