Little Stems Coming Out of My Christmas Moss

Hello, I have some Christmas Moss I attached to a log maybe 2 weeks ago and now there are these little stems coming up that do not look like new moss. This is about the best pic i could get. Can anyone tell me what these are? Right now they are maybe a half inch tall with two green leaves on them. I appreciate any help.

 

Can you provide a clearer picture?

 

Maybe I'll have to wait until they get bigger. I took like 20 pics. this is the best i can get.

 

Do you happen to have duckweed in your tank?

My only other guess is Hygrophila polysperma.

 

No, just Amazon swords and Anubias. I guess I got some free additional plants when I bought the moss.
