Yesterday I came across a seemingly natural population of an Arisaema sp. in
Hobe Sound, just N. of Jupiter on the E. Coast of Florida. This is way
South of where I had read they occur, which was I believe somewhere around
Gainesville, N. Florida. It is in a tidal bog just W. of the
intercoastal, around Condos. 'A' and 'B' of a development called 'Loblolly
Bay', built on stilts over this black, wet smelly soil, sand fly infested
swamp!!! A LOT were in bloom, the plants varied in size from 12" or so up
to 3 - 4 feet! I know that there are two species recorded from Florida, A.
dracontium and A. triphyllium ( ? ), any know how I can tell the
LOTS of Peltandra virginica in this area also!!
I also noticed that Philo. 'Xanadu' is beginning to come into bloom, single
inflorescences emerging from the leaf sheaths of the younger leaves on
mature plants everywhere!

A. dracontium is distinguishable by its single compound leaf with 7-12
leaflets, its small green sheathing, and its long-caudate spadix
A. triphyllum is 3 foliate. There are several ssp. which vary greatly in|
size and other characteristics.
However, A. triphyllum ssp quinatum (Buckley) Hutt., which has a very
restricted range in the deep south and is found only in Georgia, northern
Florida, Alabama, Mississippi and Louisiana, is penta-foliate. It grows
in moist, shaded situations. It tends to be smaller than the other
subspecies and its leaves are usually glaucous beneath and penta-foliate
though they are sometimes tri-foliate or lack gaucescense. The spathe
tube is smooth and topped by broad, flaring, but not depressed flanges.
The spathe blade is unmarked green and oval or orbicular with an abruptly
apiculate tip. The cylindrical spadix appendix is very slender and
curved toward the opening of the spathe. Its chromosome number is 28.
Yours sound too big to be ssp. quinatum but it's the only American
species that is penta-foliate so it
is easy to spot.
If you can handle WordPerfect files, I can send you Huttleston's KEY to
A. triphyllum which
also comments on the other two North American species.

A. dracontium has multiple leaflets/leaf; A.triphyllum has but three. A.
dracontium ("Green Dragon") has a very narrow green spathe; Aa triphyllum has
the usual "Jack-in-the-pulpit" shape. Its spathe can be striped or not, green or
yellow or brown or red or purple.

That would be neat if it were A. dracontium. Maybe it would be a more heat
tolerant population. We have tried it several times here but it never
emerges the next year.
