Floral anatomy question
Cereoid+10 schreef
Just because you read it that doesn't mean you understood it. + + + That is true enough. Understanding is something that must show in comments made + + + It is essential that one be familiar with the actual genera and species otherwise the cladistics and family trees are total fantasy. + + + A big statement. Actually "familiarity" with a taxon is something that comes slowly. Even the world experts on certain families may learn something new about 'their' families after decades of working on them. Following the publication of the insights of the APG new characteristics are coming to the fore as potentially important so that "familiarity" shifts in content and gets a new meaning all the time. + + + Your accepting the descriptions of the orders and families on faith is laughable because many include misplaced genera, incorrect assumptions and errors. That they admit much of what they cite has been based on second hand info is not encouraging. Some of the recent papers actually compound the errors. They do admit that whole scheme is tentative and provisional anyway and not gospel set in stone. That the incomplete info has been copied into textbooks as if it were fact is even more problematic. + + + Sounds as if you could do a good job reporting errors you spot, allowing these to be corrected? + + + No more than the so-called Eudicots strictly have only two cotyledons in all genera and species. + + + It is the same for the eudicots as it was for the dicots. See earlier in this thread + + + Of course the primitive dicots do not all have strictly trimerous flowers. + + + How good of you to acknowledge this + + + Some of them have derived arrangements or are lacking parts. + + + Slippery stuff, these assumptions about what character states are derived . + + + The floral parts in Nymphaea are actually spirally arranged but they are trimerous in most of the other genera in the family. Stewart Robert Hinsley is the one who originally asked the question and was confused by the family trees. + + + Maybe you should reread the original question? + + + Since when did he become the expert? His only source of info has been the outdated info on the internet as has been yours. Now, you are definitely wasting my time with stupid replies. + + + Oh pardon us, oh exalted one, whose information sources are so much better than the internet (which is a good thing since he cannot find even the NYBG on the web) PvR |
