REGARDING MONOCOTS & DICOTS
|Instead of the world of flowering plants -- the
angiosperms -- dividing neatly into monocots and dicots, studies using gene sequencing
have shown that the situation actually looks more like the branch from the Tree of Life shown
below (Many experts would disagree in some or most details):
Traditionally all the above groupings other than monocots were regarded as dicots. Today the monocots are kept as before, but the dicots have been split into the various groupings shown. The eudicots, or "pure dicots," are what remains of the former dicot group. An enormous number of species are still regarded as eudicots -- about 75% of all flowering plants!
Relative to the vast number of species among the monocots and eudicots, a fairly small number of species belong to the other groupings. The most numerous non-monocot and non-eudicot species are found in the large-flowered magnoliides and the waterlilies of the Nymphaeaceae. Therefore, we amateurs are not being grossly messy by continuing to think in the simple, "outdated" terms of monocots and dicots.
