I planted by seed this year and didn't do a good job of marking
which was which. What I thought were watermelon plants, clearly
aren't. They have leaves like cucumbers but seem to be in clusters,
rather than alternate. They also have stronger points on the leaves
than cucumbers.
My hope is that I'm growing something other than just cukes! Not a
big deal as eventually I will know! It seems like there should be a
cucurbit taxonomy reference, but I can't find it.

While your cucurbit seedlings may look slightly different (or not) it is
very hard to say which is which unless you have a known exemplar to compare
against, even then they may be so similar that you cannot be sure. There is
no simple rule like 'all cucumbers have a ....." or 'all watermelons lack
.....' You will probably have to wait until they grow up when the
differences are clearer.

You should pay closer attention in future as they don't grow to the same
size and you should allow for this when planting if you don't want your
pumpkin to stomp on everything else.
