Do's someone know how to differency between : Odontoglossum, Oncidium,
Bulbophyllum, Miltonia and Zygopetalum, according to their bulbs ?
Since many months ago, I try to find this information on internet, but, I
always find books to buy !!!
If somebody can indicate a site to me, I will be very grateful to him/her.
Best regards.
Mido.
