The first picture is a Mtssa. Dark Star 'Darth Vader'
The second one is a Cryptoenrum latifolium very small but a heavenly smell at night.
The Cattleya NIOD is just getting ready to open up.
the fourth is a Bolopetalum Midnight Blue ‘Cardinals Roost’ that should open any day.
and the last is a Oncidium Noid that should open any day also.
Very nice Mtssa. Dark Star. I have the same clone, though it's teeny tiny and years from blooming. Number 4 looks very interesting. Be sure and post a pic when that one opens.
