Smell? Flavor, if you've tasted a leaf? Savory has a nice spicy aroma, and flavor. It does have the look of savory, though my winter savory grows much bushier than that. I've never had much luck with summer savory, and what I've grown hasn't been that full growth--the leaves are much more spaced out. But you would have planted annual summer savory anyway and I would assume known what it was.

It looks like it could Epazote; Epazote (ehp-ah-ZOH-teh) is a pungent herb that grows wild in the United States and Mexico. Strong-flavored and leafy, epazote is used in Mexican cooking, particularly in Yucatecan dishes. It is also a carminative, which means it reduces the gas associated with beans.

I have only found the back stamped NO 326-3P MAH and written also with a 169. I see that the drawers are made with tongue and groove and just a flat head screw is holding the handles on. Pretty sure that MAH means mahogany.
