My eyes may not be the best but if you look at the first pick third node up from the bottom left side what is that? Maybe you can get a closer look or picture.
hehehe, that you will see all over the plant... it's a secondary type of leaf called a Stipule, you'll see those every node eventually. The hairs(female) or balls(male) will sprout between there and the stem... or new growth/stem will sprout.
Edit: Xlr8 and I posted at about the same time... his pic explains everything.
