The size is all "wrong" for this plant...I've searched and searched and all info points to it being a mini no bigger than 4 inches tall.
You might just have the King of Den oligophyllum!
The longest stem on mine is approx 7" long. The new ones are fast approaching that length as well. I have seen the references to mimi size and just ignored those for my plant. I do believe Karren's is oligophyllum as she said.
