Floral anatomy question
A wheel has come off here?
Aren't you the one who is supposed to answer such questions, rather than pose them? Not sure this question has a real answer: the "Basal tricolpates" are something of a mess in this respect with Menispermaceae having a 3-merous perianth, as well as Berberidaceae, etc. I will play it safe and quote from Judd & al (Plant Systematics, a phylogenetic approach, 2nd ed, 2002): "Core Eudicots: [...] These plants have usually 4-5 merous flowers with the perianth differentiated into a calyx and a corolla; placentation is ususally axile" p307-308 PvR ========= Stewart Robert Hinsley schreef Of which group of angiosperms, is the trait of a 4- or 5-merous perianth, of two morphologically distinct whorls, an apomorphy? -- Stewart Robert Hinsley |
