 | | Bremer (2000) suggested that the split between Acorales and other monocots could be dated to ca 134 mybp, a date also used in a more recent and comprehensive analysis that formed the basis for dating the age of monocot groups in general (Janssen and Bremer 2004). |
 | | Although a Vorläuferspitze is common, it may be that in the Acorales and Alismatales in particular the blade develops from the upper part of the leaf primordium, i.e., are similar in this to broad-leaved angiosperms, so the "typical" monocot leaf development may be a synapomorphy of a subgroup of the clade. |
 | | Colleters may be a synapomorphy of monocots or of independent origin in Acorales and Alismatales, within Araceae, for instance, they seem to be known only from very much embedded genera such as Philodendron, Cryptocoryne and Lagenandra (M. Carlsen, pers. |
