        O. debilis has a bulb, the stems are weak and curving, extremely susceptible to rust. 


        O. articulata var. rubra, besides other characters has a vertical rhizome formed by several "balls" one on top of the other. Sorry for the crude non botanical description but it can not be mistaken on this alone. Scars of old petioles are clearly visible as horizontal marks on each "ball". Photos in the link you provided are correct.
