Colocasia

From: "Eduardo Goncalves" edggon at hotmail.com> on 2001.02.12 at 19:30:29(5932) Dear Aroiders, Anybody out there has some kind of solid knowledge with Colocasia esculenta varieties, cultivars, etc? Sometime ago Peter told us that there was three varieties: C. esculenta var. esculenta (small, slustering tubers), C. esculenta var. antiquorum (large, solitary tuber) and C. esculenta var. aquatilis (long stolons). Are those varieties published anywhere? (i.e. with authors, etc) What happened with variety illustris? What about that form with an yellow blot in the middle of the leaves? The only complete treatment I have (my Precambrian 'Das Pflanzenreich') cites lots of varieties and I wonder most of them became synonims. Other interesting thing is that Engler never use tuber characters (except for the description of the variety aquatilis) so this is a new approach. Who did start to use tuber information on the classification? Engler's classification uses the proportional lenght of the sterile appendix. Is this still important or was it proven to be highly variable (like almost anything in aroids)? I am sorry if these questions were already answered before, but I couldn't find any satisfatory answer in the aroid-l archives. Very best wishes, Eduardo. +More _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
