The one on the left could well be a G. Baldianum ( hybrid )
I have seen lot of plants named as G. baldianum recently, named or in un named clumps. But they have in fact turned out to be hybrid plants, possibly with G. Shroderinum.
I have quite a few of these plants meself.
G. Baldinum has a very rich ( red ) flower with white almost translucent tips to the lower down flower pelts just out of view. The type G. Bldianum at ( nash's garden ) also has a smell that carried in the air. Smells a bit like a musty algae mixed with vinegar
The plant on the left doesn't look too healthy. maybe it needs some TLC and putting in the dappled shade, or giving it a little more water. Flowers will prove if it is or not G. Baldianum true.
