Responding to Iain: I'm not sure how strictu the sensu is, insofar as 
the seed came from the NARGS exchange labeled v. pricei -very dwarf.  
Sown 11/91; Bloomed 7/94. The resulting plants were certainly 
pricei-size; they died out some time after blooming.  Seed from them 
sown 1/95 bloomed 7/04, and it is those that are the current full-size 
ones.  I grew another v. pricei, received as a plant from NARGS, that 
bloomed 7/91 and then died so could not have entered the mix, and 
that's the extent of what I've grown.  I have not paid attention to 
whether there's been subsequent seed-set.
I've assumed this simply reflected genetic variability within the 
species, and since I have no information about the actual parentage of 
the first batch of seeds, beyond that they were of garden origin, I can 
hardly rule that out, but I would be very interested in further 
thoughts.

If I may could I contribute one comment and ask for clarification on 
one of the
posts please.

Ref: Jim Jones and his 'long journey' with Lilium formosanum var. 
pricei.  Am I
understanding the contribution on this post correctly?
Namely, the progression from seed of the dwarf form of this taxon L. 
formosanum
var. pricei, sensu strictu, to a situation now where
following the resulting passage of generations from seed has resulted 
in the
production of progeny through multiple generations resulting
in the reversion to the nominate form i.e. L. formosanum v. formosanum.

Could Mr. Jones help a little please by saying how many generations are 
involved
from the outset to the present, roughly; and could he also
say whether or not he also grows any other types or forma of L. 
formosanum as
well please. I suspect I may well have miss-understood
the reading of the post and apologise in advance if so, because I am 
struggling
with the concept of reversing the evolutionary process described
in such short time and generational scales. Without crossing i.e. 
hybridisation,
controlled or accidental, between the montane forma with the
nominate coastal forma of this, or any other similar taxa, I think 
there needs
to be some other influence[s] at play here to explain such a radical
transformation but I would be very grateful to learn more and if 
perhaps if
relevant I might refer to this development in the new monograph please.

Ref: Lily bulb handling in a general sense. My experience of the way 
lily bulbs
are handled between supplying nursery, wholesaler or exporter
is limited so far, with one excellent exception to that of Tony Avent's 
nursery
in America, to what happens here amongst European and Chinese
sources, with very few exceptions, where the bulbs have their roots 
trimmed to
such an aggressive extent that the mortality amongst lily bulbs
is consequently horrendously high. For anyone interested, as a result 
of a wide
range of trials here I would suggest that there isn't any room for
doubt now that the best treatment seems to be one in which the root 
system as
existing in late summer and autumn should be left more or less
intact as far as possible, within reason, and the bulbs shipped in that 
way
perhaps with the roots gently washed out from any soil or other material
and packed in a breathable type of polythene bag or standard robust 
type of
paper bags developed for shipping bulbs while using some sort of 
inorganic
material or peat moss that can act as a buffer against rough handling 
in
transit.

The problem for European, for which read largely Dutch bulb suppliers, 
it seems
that their standard means for processing lily bulbs prior to transit
is to treat them as they have done for over a century now with regards 
to other
genera such as Narcissus, Tulipa and Iris all of which have a degree
of protection from their 'tunics' or outer scales, something lilies 
clearly
don't have. Also, the period of root development in Lilium works to an 
entirely
different 'beat' than species within these other genera. I don't want 
to drone
on, however, no doubt there are some species of Lilium which behave
differently, never the less in my expereince lilies initiate important 
new root
development during the autumn and early winter while soil retains some
residual heat, this enables them to get off to a prompt start when 
spring soil
temperatures kick in.

I would welcome any comments or contrary views if anyone has the time 
please.

Regards, Iain
