From: "Eduardo Goncalves" edggon at hotmail.com> on 2000.06.27 at 01:42:23(4931) Dear Tsuh, Yes, there is only one cladogram published for Aroids (whole family). It concerns analysis of sites for restriction enzimes (i.e. deals with DNA) and was published by French and collabolators (references bellow). It is more or less as follows: +More Proto Aroids (Gymnostachis,Orontium, Symplocarpus) \ / \/ Monsteroids+Spathiphyllum+Holochlamys+Anthurium+Pothos \ / \/ Lasioideae \ / \/ Calla \ / \/ "Philodendroideae"(Including Zamioculcadeae, Spathicarpeae \ / Zantedeschia, Montrichardieae...) \/ \ \ "Aroideae" (Including Caladieae, Areae, Colocasioideae, Amorphophallus, Lemna, Cryptocorineae...) There is also a second one that was partially published in "The Genera of Araceae" by Mayo, Bogner and Boyce, but genera are not showed in details. It seems it was based mainly on morpho-anatomical features. The final cladogram seems to be in preparation, to be published by Mayo, Bogner, Boyce, Murata and Yokoyama. Well, they cite this "future" publication in the references of "Genera of Araceae". Many others using DNA sequencing are in preparation, including mine on Spathicarpeae sensu lato (including Dieffenbachia and Bognera), but most are only partial and I don't know when we will have another one for the whole family.
