Time to chime in,

I would be sorry to lose pangii as a name, as it is now quite widespread =in
the UK under that name, but IF it is not, then so be it.  

Guy's appeal for data prompted me to get out and look, maybe this will
start the ball rolling as there doesn't seem to be a lot coming in !.

Of what we have left here there are 27 in flower at present, Guy asked
about variation.  I am only reporting flowering, flowered or
about-to-flower plants, juveniles mught slew things.

27 have plain green shiny leaves
27 red-edged +/- wavy and entire margins, none variegated none serrate in
any way. Of these two have a very deep green leaf, the colour of dark gre=en
bottle glass, the others are mid to lizard green
27 have 2 leaves, 2 have one leaf
of these 25, plants (50 leaves) all have three leaflets, all have the
central one petiolulate, none have more than one petiolulate leaflet.  Th=e
Two exceptions each have one leaf, one has three leaflets, central one
petiolulate.  The other plant has an apparently malformed leaf with one
leaflet developed, one shrivelled and one apparently absent. This
"malformation" is an assumption on my part, but as the other two leaflets
are in the correct positions I think it a fair one.
So far all very very ven and I am sorry Guy that I can't give you much
variation so far.
22 plants have unequilaterial leaflets, 4 have perfectly equilateral
leaflets. 1 is malformed
The variation that might interest you most is in the timing of spathe
emergence, since only in 5 plants can I truly say that the spathe has
emerged before the leaves, the rest have emerged with or even just after
the leaves have unfurled.  This is tricky as the whole thing is a sliding
scale of constant development, but I suspect that some of this is
temperature influenced. 

Colour variation is considerable, the depth of colour in the spathe is
noticeable, but I think is much influenced by age, they get redder and
redder as the spathe gets older.  The spadix is remarkably variable. Most
are like white candlewax, but the degree of intensity of the red flecking
is notable.  It seems that it is darkest at the base of the spadix
(appendage) and gets paler to the tip, but in some it is very dense.  The
spadix is pink in the two plants that have the dark leaves, AND the stems
are very strongly marked in these two plants.  One spadix is bulbous at t=he
tip, not as much so as sikokianum but markedly swollen.  This particular
plant has no notable color variations associated with it, just a swollen
nose !

By the way, A.elephas ex Kaichen is normal sized here, I wonder if the si=ze
of the inflorescence is controlled by the size of the tubers ?

More on this is that this year Kaichen are offering not only sp "X" (that
was elephas last year, can't remember their number) but also A. elephas a=nd
A.wilsoni (which are by repute synomyms) as well.

This is getting verbose, must stop
