Arisaema triphyllum - rear view of spathe
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.
This is a dark flowering form, although from the outside
of the flower, the dark purplish-brown color doesn't show
through and the spathe appears green from the rear.
Notice the 10-12 white stripes and the strongly curled-
over "hood". Compare this photo with the rear view of
the hybrid A. sikokianum x triphyllum, for some
