Dear Linda
The plant that you painted so beautifully is Bulbophyllum orthosepalum
(syn. Bulb. hashimotoi) a species that was recently described. Bulb.
macrobulbon was a species that was a little confused in cultivation and
there have been several new species that have been described in this section
of the genus. If you search on the web you will find other images of the
plant as well as images of true Bulb macrobulbon.
As for your Lycomormium there are only a couple of species in the genus
and yours seems to most resemble Lycomormium squalidum from Peru.
Hope that was of some help to you
Sincerely
Marc
