I have mystery squash

[LeahBoo]

And I have a community garden, so I don't know what was in the garden last year.

I planted two zucchini and two straightneck squash in my garden and my sister's garden. I watched hers come up, but mine didn't. Finally, one came up. Close to where I planted one of the straightneck squash. Good, fine. I replanted the zucchini and all is well. Until I looked closer and the straightneck squash plant has "arms" like peas and cucumbers (there's probably a better name for these). Neither the zucchini, nor the straightneck have these. My sister also planted spaghetti squash, and these have them, but she didn't plant them anywhere near my garden. And she spaghetti squash is viney, mystery plant is growing like a zucchini, more bushy than viney.

Any ideas? It has tons of male flowers, but no female flowers or fruit.

It could be any squash, really. Pics would help, though. Are the male flowers only on the main stem? If so, I'd say you've got your zucchini or straigtneck. If the flowers are on vines that branch out, then it's something else, though you really won't know just what until the female fruit come along.

If you pinch off the end of the vine, the plant will start sending off lateral vines that will start producing female flowers/ovum. Good luck. I've had 2 mystery squashes/pumpkins show up in my yard- birds or whaterver very nice.
