Gucharan ji , Thank you for appreciating whatever I have to share but I never refer to myself as an expert but as a 'constantly aspiring aficionado' and that is not false modesty...knowledge is a reverse pyramid (which raises more questions with each answer "The more you know , the more you realize that you don't know") and in that regard there are no 'experts' but only 'constantly aspiring aficionados'.
I am glad to share (and guide ) relative to what I am aware of but my knowledge is far from complete and never will be... The main difference between Ipomoea coccinea and Ipomoea hederifolia is the calyx and the pedicel which I shared in the PlantFiles (when I was still a member of that site) Here are some links Ipomoea coccinea - reflexed pedicels http://davesgarden.com/guides/pf/showimage/139580/ http://davesgarden.com/guides/pf/showimage/174039/ http://davesgarden.com/community/forums/t/688746/ Ipomoea hederifolia - pedicels remain erect http://davesgarden.com/guides/pf/showimage/173738/ http://davesgarden.com/community/forums/t/789528/ http://davesgarden.com/guides/pf/showimage/167703/ http://davesgarden.com/guides/pf/showimage/81986/ read the lower portion in English ( I use google to translate into Spanish) where I address the awn and arista http://www.infojardin.com/foro/showpost.php?s=8e6211ae5ba5248ff679dbc95bb8f134&p=5037636&postcount=9 The Tropicos site lists Ipomoea coccinera L (which should indicate legitimate) as having 3 accepted names... http://www.tropicos.org/Name/8500974?tab=acceptednames Ipomoea coccinea http://www.ars-grin.gov/cgi-bin/npgs/html/tax_search.pl Ipomoea coccinea - perform your own search because searches cannot be saved in url http://ipni.org/ipni/plantnamesearchpage.do Ipomoea rubriflora perform your own search because searches cannot be saved in url http://ipni.org/ipni/plantnamesearchpage.do Ipomoea rubriflora - lists Ipomoea coccinea as a synonym http://www.tropicos.org/Name/8501935?tab=synonyms I think it is confusing to have Ipoomoea coccinea listed as a legitimate species by both Ars-Grin and Tropicos and at the same time have Ipomoea coccinea L. listed as a synonym of Ipomoea rubrifloa. The PlantList may or may not be 'correc't on Ipomoea rubriflora since this particular case is confusing in comparison to the other reference sites...so, who can know for sure at this point (?!) There are often times when someone doing field research will need to insure/ preserve their funding and so minor differences which (from my perspective) may warrant a rank of subspecies , variety or forma , get assigned to the rank of a 'new species' (!)...and the 'discoverer' who is the only one who knows the exact location , continues to receive additional funding to continue to study the new species , which sometimes never truly sees the full light of day...and I have seen this 'phenomenon' occur too frequently... Ipomoea species rarely cross the species barrier (with rare exception , e.g., within series batatas) , although subspecies and lower taxonomic ranks will cross fertilize, so when I am in doubt, I try to obtain germplasm and perform my own crossings to get a 2nd opinion from the plants because the plants surely know the degree of relationship between themselves better than our human visual observations. I am fully aware that various degrees of compatibility and incompatibility exist within species and sometimes even lower taxonomic ranks , but if the supposedly different species cross fertilize , then they are in all likelihood not different species at all...the plants do not lie... I will believe that Ipomoea rubriflora exists when I see closeups of the relevant structures that differentiate it from Ipomoea coccinea and until that occurs I will be skeptical of Ipomoea rubriflora. I hope my contributions will prove to be of value. regards, Ron on Monday, March 12, 2012 4:27:51 PM UTC-4, Dinesh Valke wrote: > > *Ipomoea hederifolia * L. > > > > - *ip-oh-MEE-uh* or *ip-oh-MAY-uh* -- worm-like; referring to coiled > flower bud > *hed-er-ih-FOH-lee-uh* -- with leaves resembling *Hedera* (Ivy genus) > - ...
