RE: Ulearum donburnsii

From: "Wilbert Hetterscheid" hetter at worldonline.nl> on 2002.05.15 at 19:33:04(8800) The hybrid product is the result of an autoplyploidisation event in the sex cells of bulbifer and that followed by a reduction in the cross, leading to a tertraploid hybrid result........ But maybe I haven't made myself clear. I am going to pubslish it EARLY APRIL 2003........ As for a serious answer: bulbifer will usually not produce a leaf in the same season when it is allowed seed set.
