Hello Eugene, I don`t remember the claims that you mention, but the world is FULL of shysters who really believe that there is a fool whose money just NEEDS to be taken every minute or so. Some claims may be based on misinformation on the true identification of a certain plant, for example I heard that there was a claim out of Indonesia of a Xanthosoma X Caladium cross, this COULD be, as the 'lines' between these closely related genera are sometimes blurred ( as they presently seem to be between Alocasia and Colocasia), and even the experts make mistakes w/ these groups. As an example of this, on pg. 208 of 'The Genera of Araceae" on the Caladium page of illustrations, 'A' and 'C' are said to be Caladium aristeguietae, this plant was ORIGINALLY described as a species of Caladium, but had been reassigned to Xanthosoma (based on a closer examination of the pollen) BEFORE this book was published, but there it is, before God and man, identified as a species of Caladium. So--- if someone used this species in a cross with say Xanthosoma acutum, they would probably succeed ( I have seen a MAGNIFICENTLY beautiful cross of Xanthosoma heribolifolium and Xanthosoma acutum done by a friend in W. Florida!), and another story of an intergeneric cross would be spawned. By the way, I have a jackalope baby here (Jack 'rabbit' X antelope), you should see how BIG he is, and size of the horns on that little sucker, and see him hop! Any offers??? Good Growing all, Julius +More hi everyone, Surely these are frangipani, Plumeria rubra (Apocynaceae)! The 'giveaways' are what look like petiole scars on the stem in the middle picture, the venation of the green leaf in the lower one, and the overall disposition of the foliage (hm... very scientific!). Though I haven't seen these variegated ones before. Growing up in Sydney, the appearance of Plumeria has been "imprinted" on me - they were planted in practically every garden in the older parts of town. As a kid, you quickly learn to recognise the climbable-looking little trees whose branches, evilly, snap off and send you crashing to the ground... Speaking of intergeneric crosses... I'm reminded of "x Homalocasia", the supposed hybrids between Homalomena and Alocasia, which I gather were debunked as a hoax? As well as "x Homalocasia miamiensis" (actually Homalomena lindenii, as mentioned in Exotica), there seem to have been "others". One I saw in York Meredith's collection back in the 1980s had somewhat sagittate leaves, variegated a bit like Homalomena wallisii. (I've not seen it since, but some Schismatoglottis look suspicously similar...) Does anyone remember these, or know what the story was? cheers Eugene Eugene Hoh Sydney, Australia --- Peter Boyce wrote: Folks I'm inclined to agree with Wilbert about the top and bottom image; certainly the leaf emergence of the top image and the venation on the bottom look 'wrong'. In fact, I'd go so far as to say the bottom image reminds me strongly of a member of the Rosaceae, Photinia x fraseri. The middle image I'm not so sure about - to my eyes there are two 'aroidish' inflorescence/infructescences in the middle of the leafy crown. I've tried enlarging the image but he quality is too poor to reveal anything definite. Aglaonema and Dieffenbachia are a fair distance apart in terms of relationship. Curiously, if someone posted a claim of a Aglaonmea x Anubias or Aglaonmema x Nephthytis hybrid (or indeed Dieffencachia x Gorgonium! (sorry Eduardo!) I'd be a lot less sceptical.

The Aglaonema group is discussing now if Dieffenbachia can be crossed with Aglaonema... I know that they belong to deiierent tribes and have different pollination biology, however the Group says to me that the Japanese crossed Alocasia x Colocasia (the same tribe). Does anybody know anything about this Alo-Colocasia hybrid?
