Transmutium
My  account of the suspected presence of a previously  unknown  element may interest readers as its discovery arose directly from  my involvement in Alpine growing.    Let  me explain - I have found that on occasions the seeds  of  delicate  alpines  are affected so that they  spontaneously  give  rise  to  mutations  - my only explanation is  that  some  common  factor in the sowings must be the cause.  Particular examples  so  far  are  Polemonium  viscosum and P.  brandegii transmuting  to  P.caerulum and P. pauciflorum respectively. Draba paysonii  treleasii produced D.aeizoeides, Aquilegia saximontana changed  into  A.  flabellata,  Townsendia rothrockii transmogrified into  ..  ,  well something and Viola pedata decided life would be much easier  as V.  pedatifida.    As a result of these observations  I  have  suggested  the  existence of a new element and  have  tentatively  named it "Transmutium" on the basis of its effects. As yet I have  not been able to positively identify the source of Transmutium  -  I  have  eliminated its existence within composts  (various  have  been  tried), seed sowing containers, chippings and water. It  is  likely  therefore,  that Transmutium is present in the  West  Berkshire  air  (  possibly as a result from  leaks  from  Greenham  Common or Aldermaston.)      Interestingly,  some  plant families seem more immune  to  the  effects of Transmutium - eg Primulacae, Androsaces vandellii and  ciliata, Douglasia laevigata and Primula forrestii (thank you  to  who ever sent that in !) were unaffected*. So too were Campanuala  lasiacoarpa (very nice), Corydalis wilsonii, Rupicapnos africanus   and several others.      The  townsendias present a problem - whereas  T.  rothrockii regressed  to something like an aster, T.mensana stubbornly  refused  to produce anything other than a very small mat of  silver  leaves  just  topped by enormous pale lilac daisies (as  you  can  imagine  I  am much disappointed that this disproves  any  theory  involving  correlation with plant families.)               

Much work needs to be done before I will be able to share my  discovery fully with the scientific world. Some gardeners I  have  spoken  to  regarding  my research has expressed  doubts  on  the  validity  of  naming of some AGS seed. Shame on them!  However,  this  feeble  theory would be relatively easy to  check.  If  all  those generous members who donate seed are ruthlessly  scrupulous  in the naming of seed then the effect would disappear. If members  are  not  absolutely sure they should still send their  seed  but  introduce a ? into their naming eg.
Draba mollisima(?) or if less  certain Draba sp. or Draba ? (sp.) if you are really floundering.      

However,  I doubt the validity of this  ridiculous  hypothesis  from  these cynical gardeners  and look forward to the  flowering  of my
Polemonium pauciflorum (really a nice plant) and to receiving my Nobel Prize for chemistry.    

* Post script - several Primula vulgaris have now flowered  as  red polyanthus.
