Plant needing identification

Hope someone knows the name of this plant which was a volunteer in one of the pots in this spring's indoor seeding.

 

Melianthus ?

That's it!!! Thanks so much.


..... and to think it just came up in the soil mix!

 

It's an indoor plant in your area. Caution: toxic if eaten, keep it away from pets and young children.

 

Thanks for the warning.
