I just posted one of Brian's photos on my website which appears to
indicate "Silver Queen" is the juvenile form of M. dubia.
Anyone who wishes to see Brian's photo and comment is invited to do so:

Harry (and others who have sent email directly),
I received some nice photos from Brian Williams this morning that
appear to support the idea the 'Silver Queen' is the juvenile form of M. dubia. Brian's photos show the
plant progressing into the adult stages. Since I can't get an absolute
verification of that fact as yet I'm hesitant to declare it so but more than
one grower has indicated the same idea to me. Of course, others differ
strongly with that opinion. The plant that was identified by the person
at the Huntington
as M. siltepecana has begun
to climb a nearby log and has only recently begun to produce holes in
the leaves. I don't consider it large enough or the holes distinctive
enough yet to photograph well but the leaves are over 20cm at this point.
I've had it in the ground for about 18 months and have tried not to disturb it
so the plant can develop as much as possible in my artificial
"rainforest".
Although I grow some plants in pots, I grow as many as possible planted
in the soil or attached to artificial logs. The soil in our atrium was
prepared to simulate rainforest conditions. I maintain a steady
temperature and extremely high humidity all the times. As a result, many
of my specimens have grown unusually large in a relatively short period of
time. As I've reported before, the A.
regale has a leave well over 70cm and is currently in
bloom. I've only had the plant 15 months and it had no leaves when it
arrived. Knowledgeable growers who visit often comment they have not
seen plants growing as large. I was fortunate enough to have spent a fair
amount of time in rainforests around the world and set out to duplicate those
conditions as closely as possible when I built the atrium nearly 5 years ago.
Several others have indicated they believe I have my identifications
backwards on the M. dubia
and M. siltepecana plants
and that is certainly possible. I just attempt to post what I can verify
from sources with more knowledge and experience than I. I invite anyone
to comment on anything I have posted on the site and make suggestions or
corrections. My only goal is to try to get the information as accurate as
possible. One thing I find most enjoyable is when other knowledgeable
growers volunteer good information attempt to help each other with good
information. So keep it coming!

Steve, I totally agree with you. This
plant seems to defy identity. I had Rhaphidophora cryptantha labeled Monstera
dubia for years so I can surely be incorrect and am quite often. I have never
seen the plant I have labeled M siltepecana revert to any type of foliage other
than what it has now. I would assume that if it were M dubia it would in some
situations revert to the sprawling climber that shingles but I could be wrong.
What is the consensus on this plant if any
from the list.

There is obviously more than a bit of disagreement on what
"species" the plant known as the Silver Queen actually is.
