Mediocalcar decorata.
Lots of photos on this little one on forum of this already. But I rarely get to post blooms I can't take total credit for these since I bought the plant with the start of the lil green buds. I just managed not to kill it before they bloomed. The blooms are about the size of a pencil eraser. It's a bit scrawny. In time I would like to find a mount and transfer it from the plastic pot.
