Florida Arisaema.

From: "Julius Boos" ju-bo at email.msn.com> on 2001.03.06 at 14:45:52(6016) Dear Folks, 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 difference?? 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! Good growing, Julius Boos +More WPB, Florid

From: "George R Stilwell, Jr." grsjr at juno.com> on 2001.03.06 at 17:16:52(6017) Julius, A. dracontium is distinguishable by its single compound leaf with 7-12 leaflets, its small green sheathing, and its long-caudate spadix appendix. +More 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. Iza Goroff +More Whitewater Wisconsin USA zone 4b

From: Eric_L_._Schmidt/LEU/CYS/Orlando at priv.ci.orlando.fl.us on 2001.03.06 at 18:18:51(6020) 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. Eric Schmidt +More Botanic Records Harry P.
