Christia vespertilionis, leguminosae (aeroplane grass or bat grass)

I looked back my old photo files and found this plant. It has one leaf out of the three leaves like stealth plane, but the other two leaves are smaller. The colour is violet too but with dis-colourisation stripes. The stems grow out from a main stem, not like the stealth fighter plant where the stem grows out from the rhizome in the ground. Are they from same family ?
