How are you doing ? All right, I understood your question.
1) Paph. tonsum is not located in Borneo Island.
It locates in Java and Sumatra Islands only. In the northest
area of Sumatra, one variety of Paph. tonsum, Paph. braemii that
is smaller than usual tonsum is distributed. And Paph. tonsum
has other variety of cupreum whose leaves and color of flower
is darker with purple red.
2) The leave of Paph. tonsum is mottled. But so many Paph.'s
species have mottled leaf. You can not identify from the leaves,
3) As you live in the best condition in nature of Borneo for
growing Paph., you had better grow it outside. But never keep
it under the sun light directly. Under trees, you may hung in
the shade. You had better keep the shade from 60 to 70 %. In
nature, they will grow east or north east side of mountains.
It means, they like the morning sunshine but doesn't like in
day time. In detail, you read how to grow Paph. on my site. English
page is available. But you have to modify slightly from the procedures
that I recommended.
4) If you could send the photo of your Paph., please send it
by e mail attached or by air mail. It is the best way to identify
what it is. The following Photos are Paph. tonsum and Paph. braemii.
Is it the same as yours ?
In the north area of Borneo, there are several kinds of Subgenus
of Paph. ,Spasopetalum like amabile, bullenianum etc. The leaves
will be similar each other. I'm looking forward to getting your
reply. Thank you.
With my best regards.
