Additional Set of Unknowns
 

Another set of unknowns is posted at this link. Will appreciate your identifying these for me.

288: Spathoglottis-hybrid?
276: Bat plant (Tacca species)--not an orchid
266: Spathoglottis
564: Cirrhopetalum Elizabeth Ann...maybe 'Jean'?
546: Schomburgkia (splendida?)
530: Encyclia (Prosthechea fragrans)
537: Zygopetalum hybrid
527: Angraecum (eburneum?)
234: Vanda luzonica
955: Masdevallia hybrid...too many yellow types, hard to tell for sure
688: oncidium-type hybrid

These are just my guesses. Not 100% sure. :)

288 Spathoglottis hybrid
276 Tacca species (chantrieri?) -NOT an orchid
266 Spathoglottis plicata (or hybrid thereof)
564 Bulbophyllum/Cirrhopetalum hybrid, possibly 'Louis Sander'
546 Laelia splendida
530 Prosthechea fragrans
537 Zygopetalum hybrid
527 Angraecum comorense
234 Vanda luzonica
955 Masdevallia hybrid?
688 Oncidium hybrid

276 Bat Plant
564 Bulbophyllum louis sander (for sure. mine just finished blooming)
546 Schomburgkia splendida
537 Zygopetalum ?
527 Angraecum (eburneum or comorense)
234 Vanda Luzonica
955 Masdevallia ?

688-Possibly Onc. (formerly Colmanara) Jungle Monarch 'Everglades'

Looks like a good call. To verify, I typed O.-J.M. into search engine, and was sent right back to this forum, an earlier thread called "Oncidium Jungle Monarch 'Everglades' AM-HCC/AOS" with a perfect likeness to mine.

Wondered if #564 might be Bulb. longissimum.

Also #688 is very much like my Odcdm. Wildcat 'Yellow Cat.' which is currently in bloom.

I may have jumped in partway on a series of posts, but how come so many unknown plants?

It is an accumulation of photos made over the past few years. In most cases, in a botanical garden the tag was missing or not discoverable. At commercial nurseries, often only the genus is printed on the tag.

I'm new to this forum and hope I am not abusing my privileges. Everyone has been very prompt and helpful with their replies.
