anonymous winter stems

I have been trying to ID this plant for about a month. I so wish that plant books would include the winter version of the plant as well as the spring and summer photos and descriptions. I am 99% certain in identifying this plant as rough bugleweed, a native wetland plant. The dots, which look like burs are called persistent calyxes. I looked at the stems and I saw dots and dashes, which reminded me of morse code, so I was going to write you all an asemic love letter, but I got distracted by the details of the calyxes, so I ended up with this photo. Which pleased me quite a bit.
