Cattleya dichroma (or Sophronitis bicolor)

Just stumbled on this post. Had the following labeled as bicolor. Don't know what it's species status is these days, but feel it certainly is a pleasing color combination.

 

I've been researching these recently for a talk. The identification is extremely confused and you see one species listed as another so many times. Your plant is a dichroma Chuck. You can tell this by the lack of a purple mid-rib, the elongated petiole (first pic bottom right) and the bicoloured flower (although this varies) I can't tell what Spiro's is. The shape, size and colour of the flowers tell you nothing most of the time.
Until we know more we should stick to these distinguishing features:

dichroma - as above
coccinea - purple midrib on the leaf. Sometimes on the edge as well
acuensis - no purple mid rib, leaves more ovate than coccinea and more leathery.
mantiquirae - flowers in summer. No purple mid rib on the leaf
wittigiana - pink flower (can be pale salmon or peachy)
brevipedunculata - short peduncle, roundish flowers with good shape (usually) Usually not red but more salmon tones. Sometimes confused with wittigiana which has a longer peduncle.

The amount of purple suffusion on and under the leaves seems to vary quite a lot from clone to clone, species to species and exposure to light. Coccinea tends to have less purple suffusion on the leaf not including the purple central vein and leaf edges.
I think there may be many hybrids of between these species which confuses things even more.

 

Thanks Mike, this is good information to keep on hand. Just curious if there are distinct blooming seasons noted for these species?

 

As far as I'm concerned, blooming times are the most unreliable guide there is!

 

Great color and shape!

 

If anyone is interested, I did get this at Andy's a couple years ago. Don't know if this was a division or just a lucky choice.
