Bulbil production

There seems to be a degree of scepticism being expressed about the 
production of bulbils from pieces of lilium scales. I do not know if the 
production of bulbils in Lachenalia follows the same principles as with 
liliums but I would suspect it to be extremely similar and I have 
experienced bulbil production from pieces of Lachenalia bulb remote from 
any base plate. Of course some Lachenalia are known to produce bulbils 
from leaf cuttings similarly to other genera such as Veltheimia. Do any 
liliums function in a similar fashion when leaf cuttings are taken?

If I correctly understand what Paige's view on this is, if not fulsome apologies, then I would like to respectfully offer a correction. 
> Following propagation experiments here involving in excess of 80 + different botanical taxa bulbil production can be achieved from almost any part of a lily bulb scale. A good example of this is e.g. with the new North American taxon L. pyrophillum which has scales in two or three parts and as recently as yesterday I potted up over 20 bulbils originating from a single mother bulb whose scales were placed in damp vermiculite in late autumn last year. In other cases where e.g. [a] Trumpet Asian species with long narrow single scales bulbils can be produced from broken scales which have no base plate tissue, and [b] the Asian Alpine L. lophophorum along with our sp. nova L. montegena which I am frantically trying to bulk up by means of both scaling as well as seeds. In the case of LL soulei and bakerianum where some bulbs last summer and autumn showed signs of basal rot the sections of the scales with rot were excised using a razor blade more in hope than anything else however t

If anyone wanted more info along lines similar to that for the seed germination already provided feel free to ask however as I am about to disappear for a back operation next week it will need to wait until I get back to work at the end of May so e-mail me then and I will try to send some info out, it hasn't been properly written up yet but no doubt it will be one of the  'to do' jobs when flat on my back.
