Mystery plant found during the front yard clean up

Although the freeze seemed did not damage Ixora in the frond yard, I found they were dropping the leaves like crazy in yesterday's windy weather.  When I started raking all those leaves, I decided they all need a hair cut any way.  Next thing I know I spent almost two hours cleaning up the whole frond yard.  Does that sound familiar to you gardeners?! 

After I did a good trim to those Ixora and Star Jasmine bushes, I found about eight plants like this hidden under them.  I don't know what they are, but they certainly don't look like weeds to me (at least I wish).  As much like free plants as me, I digged out four of them, and potted them, secretly hoping I just found a hidden treasure :)

Now, here is what I need my fellow gardeners' help!  What is this plant?  Does it worth my nurturing and caring?  Or it is just a weed that I am potting?!

When I moved to our current house a half year ago, I did not notice these plants at all in our front yard, maybe it has been hidden there for a quite while.  If so, whatever it is, it did not grow much since it still only about 6 to 7 inches long.  Of course that also could be caused by lacking of lights considering they are completely covered by dense Ixroa and Star Jasmine bushes, and also the plam trees. Here is my front yard looked like in August last year, so you can have an idea what this plant's environment is.

This is the view close to my front entry way. From the front to the back:  Sago Palm , Crotons, Ixora, and Star Jasmine.  Except Sago plam was another house warming gift from my friend, all other plants belong to the existing landscape.

This is the left side of the same front yard area.  From the front to the back:  Crotons, Agapanthus africanus (Meems at Hoe and Shovel listed this as one of the six plants she can not live without.  I love it very much as well!), palm tree (only the trunk can be seen in the picture), and star Jasmine.

The front yard faces north east, and only gets a couple of hours morning sun.  The rest of the day is pretty much in the shade or receives dappled sun light.  You can tell that mystery plant really does not get any sun, especially tucked under the Ixora and Star Jasmine bushes.

Now I am anxiousely waiting for somebody tells me I found a treasure!  Or not?

UPDATE: The result is in! "FloridaGirl" at "Peace in the Valley" identified this mystery plant is one kind of Orchids, by common name Lady Slipper. "The Rainforest Gardener" at "The Rainforest Garden" further confirmed Lady Slipper orchids are in the Paphiopedilum genus.

Thanks, FloridaGirl and The Rainforest Gardener! It is very nice of you to spend time to identify this plant for me!

Now the pressure is on, since I am not a very good orchid grower :)  I think I will keep the rest of plants in the original location for a while just in case I mess up the four I have dug out (does not sound very confident, huh?).   I will keep you all updated the progress of this plant.  Thanks again.
