Dear Tom,

Thank you so very much for the ID. Are you aware of any site where I may
view photos of this species, and are there live specimens at MOBOT or
growing in any collection that you may know of??

Thanks again,

Julius

Dear Julius,I think there is a very big clump in the aquatic plants display in Munich. It is indeed a surprising habitat for a Philodendron !!!With best regards,DavidLe 30 mai 06 ? 23:50, Julius Boos a ?crit : From : Tom Croat Reply-To : Discussion of aroids Sent : Tuesday, May 30, 2006 4:05 PMTo : "Discussion of aroids" Subject : RE: [Aroid-l] Swamp Philo. sp. from near Iguazu Falls.Dear Tom,Thank you so very much for the ID. ?

and it still bothersmeall these years later.This note was sparked by someone mentioning the late Fred Fuchs, whocollected extensively in S. America back in the 'good old days', andoftentook groups of orchid and aroid enthusists collecting w/ him. ? Manyyearsago, when I was just getting started in aroids, I met a woman here inWPBwho had returned from collecting w/ Fred just a year or so previously,shedescribed being on the bus to the famous Iguazu falls, when along aflat,straight road BEFORE getting to the falls, in a cow-pasture behind abarbed-wire fence, she saw what could be mistaken for a huge stand ofXanthosoma. ? On closer inspection (after she managed to get the bus tostop!) the plants turned out to be a swamp-growing species ofPhilodendron .?The area in which this dense stand of plants was growing, which wasobviously sometimes flooded, was dry at the time, and the 'soil'consistedof clay baked by the sun to the consistincy/hardness of red brick. ? Shehadto get the bus driver to assist her in digging th
ree plants out of thishardand rock-like 'soil'. ? From memory, the plants had long yellowpetioles,and 'carried' about 5 leaves.? The leaves were sagittate, with theanteriorlobe noticably shorter than the longer, wide-spread hind lobes, and theblades were carried with the anterior lobe pointing down, the hind lobesup.? They were not? 'self-heading', but were none the less very compact,short-rhizomed plants w/ a thick, short and elongate rhizome the colorof anAmerican sweet-potato, orange. ? It seemed that the plants could storefoodreserves in this form of rhizome.The woman had three plants, and resisted all my efforts to trade or buyonefrom here, she made a comment that she would prefer to let them diebeforeshe would part w/ one. ? During a visit a few years later, she had donejustthat, allowed them to die. ? The pots stood empty save theremanants/shellsof their rhizomes.I discussed this w/ the late and great Dr. Monroe Birdsey, and would youbelieve he too had seen and collected the exact plants at the exact

Doesnt P. brasiliense also grow aquatically, or at least partly submerged and from the same region as P. tweedieanum?
Very interesting plants!

Dear Michael,

Yes, P. brasiliense has the same ecology, i.e., both species grow in
marshes. However, P. brasiliense occurrs more to the north (S?o Paulo and
Rio de Janeiro state), near the shore, whereas P. tweedianum grows to the
south-west, along the Paraguay river basin.

Very best wishes,

Eduardo.

Dear Julius:

I don't think that I have this species in cultivation. There
are images in the Araceae of the Flora of Paraguay (Figure 7 on p. 24).
Do you want me to send it?

Tom

Dear Tom and Julius,

We have P. tweedianum cultivated in our collection here at UCB, together
with the other aquatic Meconostigma, such as P. brasiliense, P. uliginosum,
P. paludicola and P. dardanianum. It is very easy to cultivate following
Julius' methods for Urospathas.

Very best
wishes,

Eduardo.

Here is the website for our Amorphophallus titanum which should open
sometime next week. There are photos, etc. and if not up eventually a
webcam. I am off for vacation so will probably miss it. Figures.
Enjoy...

Dave,
Came by to see the flower last Friday but couldn't get close-up. Still amazing through the glass.
How will you be storing the pollen? Will it still be viable next spring? I would like to try to make some Amorphophallus hybrids.
