OK, it isn't bulbous, but it's rhizomatous (FNA: "Roots fleshy, contractile. Rhizomes thick, to 30 cm or more"). So it's fair to say it has a (sometimes substantial) fleshy subterranean storage organ, though that is a rhizome, not a proper bulb. The contractile roots grow out of the rhizome. I believe I left its eligibility for discussion here an open question in my original posting.
