Re: [aroid-l] Selloum/Bipinnatifidum

From: "Julius Boos" ju-bo at msn.com> on 2003.05.10 at 20:04:23(10233) Dear Susan, I`m going to take this opportunity to put in a plug for our International Aroid Society! If you are or become a member ($20.00/year), you will have access to some fantastic information by authors like Dr. Eduardo Goncalves who, in the latest issue of our journal '"Aroideaea" published a most interesting paper on this group of Philodendron species. In the previous journal there was another paper also with great information, photos and illustrations also on species within this group of Philodendrons! In reading Eduardo`s note to you and the list, and reading his truncated 'key' to the species in this group, it would seem to me that based on his comments about P. mello-barretoanum, with its hard scales on its stem that do not easily detach (I have received a pretty severe laceration on my hand caused by my careless handling of a plant by these spine/knife-like scales!!), it, and NOT p. bipinnatifidum is the species in massive tissue-culture cultivation here in the U.S.A. As seen in the latest issue of Aroideana, our paper describing P. xanadu as a good species, hehein S. Florida the 'local' and very common Philodendron which is sold locally as P. 'selloum' but which for years was thought to be P. bipinnatifidum, has a huge spathe with a green exterior, and persistent and HARD spines on its stem. Eduardo says that in true P. bipinnatifidum the spathe can vary in color, so my question is what color spathe does P. mello-barretoanum have? Remember, my friends, the study of aroids is far from complete, we are learning new 'stuff' every day!
