Hi, Jim Waddick asked me to post the following question and pictures (on the wiki page). " http://pacificbulbsociety.org/pbswiki/index.php/… Here's a plant of Oxalis compress with large double flowers, but what is going on here.? The flowers are part of a good size clump of leaves, but then there is a near leafless stem going down almost a foot to end in a tiny corm barely under the soil. Unfortunately a greenhouse weed. Notice that the clump of foliage is NOT resting on the ground and has no hint of roots. Also note the picture of the tiny tuber. The tuber is attached to the main stem and there is a small bud just starting to develop where the tuber meets the stem. A lot of odd structures here. " Apparently the 3 billion users of FaceBook have failed to solve the mystery. Time to ask the experts. Short URL: https://goo.gl/kYocds/ -- David Pilling http://www.davidpilling.com/
