ellidro Posted September 30, 2021 Report Share Posted September 30, 2021 Has anyone received their IPS Palm Journal Volume 63? It states Chambeyronia houliou was an undescribed species, not a variation of macrocarpa and will now be called Chambeyronia houailouensis. Additionally it appears Kentiopsis and Actinokentia will be lumped into the Chambeyronia genus. Changes as follows: Actinokentia divaricata > Chambeyronia divarcata Actinokentia huerlimannii > Chambeyronia huerlimannii Kentiopsis piersoniorum > Chambeyronia piersoniorum Kentiopsis oliviformis > Chambeyronia oliviformis Kentiopsis pyroformis > Chambeyronia pyroformis Kentiopsis magnifica > Chambeyronia magnifica Chambeyronia lepidota remains unchanged Thoughts? Going to be very hard for me to get used to this! 8 7 Encinitas on a hill 1.5 miles from the ocean. Link to comment Share on other sites More sharing options...

Dave-Vero Posted September 30, 2021 Report Share Posted September 30, 2021 The molecular data are really clear and the paper provides all the scholarly documentation. It speaks well of what can sometimes be done by studying cultivated specimens. Note the determination that the name Chambeyronia was published months earlier than Kentiopsis, so has priority in the nomenclatural system. I get to inform my neighbor (who I persuaded to accept a gift palm) that their thriving specimen is now Chambeyronia oliviformis. 1 2 Fla. climate center: 100-119 days>85 F USDA 1990 hardiness zone 9B Current USDA hardiness zone 10a 4 km inland from Indian River; 27º N (equivalent to Brisbane) Central Orlando's urban heat island may be warmer than us Link to comment Share on other sites More sharing options...

Can't dismiss what carefully analyzing DNA turns up. Imo, compared to similar re-examination of plants within various genera / families, this seems to be a pretty smooth transition. Guarantee, changes made ( and those still being assessed / proposed ) just among Cacti and/ or Agave are even more complex / head -scratchers at times. " Lively " discussions there can be almost as bad as when Acacia were broken up and shuffled around into various other Genera. As someone recently expressed while having a similar discussion, " Get used to it.

sonoranfans Posted September 30, 2021 Report Share Posted September 30, 2021 the all too frequent changing of palm species names smears the practical identification process for the hobbyist. The unfortunate fact of the internet is that those older names tend to stick around for a long time. At one point, I recall they wanted to lump all the Caribbean sabals as sabal palmetto. I hope genetics someday replaces or at least stabilizes taxonomic identification of palm species. 1 Formerly in Gilbert AZ, zone 9a/9b. Now in Palmetto, Florida Zone 9b/10a??

DoomsDave Posted September 30, 2021 Report Share Posted September 30, 2021 I remember, a long long time ago, when they consolidated all of the Dypsis into one genus, when, before there'd been Dypsis, Neodypsis, Vonitra, and a whole flock more. At least Dypsis fits on a license plate . . . I think, too, that the gene review will also show what species really are separate and what are closely related variants of the same thing. For example, I've often wondered about D. oniliahensis Droopy and not droopy. Let's keep our forum fun and friendly.

sonoranfans Posted October 1, 2021 Report Share Posted October 1, 2021 If these are only partial genome reads there could be "lumping" of genetics. I work with geneticists who use DNA reads for (I cant say), the read depth can cause "lumping" if inadequate, plus the risk of not measuring all critical parts of the genome for clean ID. The different size seeds, morphology etc are all encoded in the genes. Failure to read the right gene segments or not use enough read depth in an ID could cause lot of "lumping" of modestly similar genetics. You cannot discount the morphology differences, they are genetic, no doubt. If they are being read someone had decided they are not significant, a tough job. The question is are they reading all the relevant segments. Apes and humans differ by ~2% of DNA sequence, palms will have similar redundancies, perhaps even higher. It might be the science here still needs to get worked out. All great science is bourne of failure experiences.

DoomsDave Posted October 1, 2021 Report Share Posted October 1, 2021 Hmm. Bear in mind that many classifications of palms were by botanists in "ivory towers" working off dried dead specimens, some of which might have been collected even a century or two earlier. That would seem flawed in and of itself. Parts can crumble and be lost, or have been omitted entirely from the original collection. I'd be a lot more inclined to view relationships based on genomic material in a positive light, though the usual scientific rigor should be applied, in particular analyses by different persons with the same results. Or a way of accounting for differing ones. In any case, sending Dr. Dransfield and Jeff Marcus down to Madagascar was a good idea. Each has vital, if different knowledge to bring to the subject. Jeff knows what the babies and the seeds look like in life. 2 1 Let's keep our forum fun and friendly.

sonoranfans Posted October 29, 2021 Report Share Posted October 29, 2021 DNA sequence "matches" you hear about in crime ID typically involve a tiny fraction of the human genome due to the huge costs of reading and analyzing the whole genome. When you are identifying an individual, all sequence data over the whole genome matches exactly, so selection of a small fraction of genome sequence for a match is much easier, and you get those ten million to 1 odds. Assessing familial closeness within a family and relative to other families is a much tougher task, and no you don't get odds as there are no direct matches. If the scientist has to limit cost of sequencing by using a small fraction of the DNA, it may not be good enough to avoid "lumping" in the familial clustering analysis. I have performed this analysis with fractional DNA sequencing information knowing the answer, fractional DNA coverage success depends on where you choose to measure on the genome and how big a fraction you use($). Then there is the number of reads or the read depth that is important to reduce noise. If you don't take enough reads or select the less than ideal segments you get noisy data and that can lead to lumping. Starting with a known answer allows you to see these issues clearly, as you have "truth" and then look at what DNA sequence says. And just because an article is peer reviewed doesn't mean it won't be found incorrect later, science evolves. Peer review is just a needed safeguard, its not a guarantee of truth. WIthout peer review, we would have the internet where so much is incorrectly assumed to be true. I am patient with this process, all new science requires patience, not expectations of absolutes. In 10 years they will know so much more than now, this is a start. 3 1 Formerly in Gilbert AZ, zone 9a/9b. Now in Palmetto, Florida Zone 9b/10a??
