Hi all,
I was just watching a lecture on monocots vs. dicots (or eudicots) and the lecturer said that monocots can be identified by the leaves having parallel veins running through (like grasses and corn) and that dicots have more complex veins. Also, dicots can be identified by having two seed-leaves at 'birth.'

Apparently, araceae are considered monocots... but their leaves have one center vein and then secondary veins perpendicular to the center. Other monocots just have parallel veins going one way.

I don't understand how they are monocots, can someone clear this up for me? nodding

Uniform or parallel veining may be more common with monocots than dicots, but it certainly is not a defining characteristic as there are many exceptions, as your photos demonstrate.

Oh that makes sense! I was under the impression that it was a defining characteristic, but I guess things like seed leaf number are more important (and/or there are lots of combinative phenotypes that represent monocots)

Thanks @WillC!
