The photos below were taken by Nhu Nguyen. The 3rd and 4th photos are closeup photos of the flowers and inflorescence. They also show the powdery quality of the underside of the tepals. Photo 4-5 shows the bulbs dividing from two to four bulbs. The last photo shows the bulb which lays in the ground horizontally just as pictured here. The remnants of the rhizome can be seen on top of the bulb.
