Very nice haul, Ursula. I ran these through OrchidWiz just to see if anything interesting would come up. Here is what I found:
Den. linawianum - Old species, registered in 1861, pretty flower
Tct. Niu Girl (Tblm. kotoense x Crtn. fesselii) - Really cool light orange bloom. I've never tried to grow one.
Sophronitis [S.] coccinea - now just called a Cattleya. Brilliant orange flower, very plain but pretty. I couldn't find anything about the '4N'
Oeceoclades [Oecl.] spathulifera - Great flower here, gold metallic with an interesting lip. One of those 'knock your socks off' blooms
Lc Sakura Sky x C. Horace - has a name now: C. Dainty Pink (C. Sakura Sky x C. Horace) Note the Sakura Sky change
Pleurothallis palliolata - Cute little gold flowers growing right on the leaf. Another nice species
Tolumnia Genting Yellow - I can't find it. There is a Tolu. Genting Angel, Genting Fairy and a Genting Rainbow but no Yellow. Not yet registered??
Asctm Mona Church - is now V. Mona Church (V. miniata x V. ampullacea). Pretty light pink flower with some yellow on the lip.
Cne. Green Light - is now V. Green Light (V. vietnamica x V. falcata). I couldn't find a flower photo.
Renanetia Sunrise - is now Rntda. Sunrise (V. falcata x Ren. imschootiana). Another bright orange flower, beautifully shaped. Love it!
This one took some work. First of all, Paph. ang-thong is now Paph. godefroyae. Part two is that (Paph. godefroyae x Paph. niveum) now has a name:
Paph. Greyi. So now I look for (Paph. Greyi X Paph. niveum) and, as luck would have it, I found Paph. Mystic Isle. So, your new orchid is called: Paphiopedilum [Paph.] Mystic Isle (Paph. Greyi x Paph. niveum). It has a pretty pink flower with dark purple spots.
All in all, nice haul, Ursula!
