anubias nana

You can anchor it to rock/wood/decoratoin. It can have the roots put in the substrate, but the rhizome <lateral fingerlike thing> should stay unburied.
 
the rhizome keeps growing and new leaves are produced. I generally split the rhizome wiht a minimum or 3 or 4 leaves.
 
I agree w/ jinx!

I have all mine rooted in the substrate, with the rhizome unburied.

I haen't split mine yet...currently I have one that's probably 4-5" long with at least 10 leaves. Maybe I should do that.......
 
Yep, it's the long, green stalk-like thing that's between the plants and the roots...

And any stem plants like rotala can go right in the substrate. Pick off any leaves towards the very bottom before the rot away from lack of light.
 
I just use my fingernails to split anubias. They break pretty easily. Rotala as was said just goes in the substrate, it grows very readily and quickly
