Check the column of the orchid. Thats the interior part of the flower with the anther cap. Its the part beneath the petals, sepals, and labellum thats attached to the main stem of the flower.

What should thay look for under the column?

Omg.. Seriously is labiata?

What do you mean by double sheath?

lueddemanniana is known to have a "horned" or "winged" column, two points on the sides, whereas other species usually have a rounder column.

A double sheath is a sheath inside of a sheath - like an extra fold. You can shine a light from the back of the sheath to see if it's just the one, or if there's a second.

[Louis_W]

Sheaths are like thin, small, modified leaves at the center of a cattleya leaf. The protect the buds as they start coming out. Some cattleyas do not have them, most have one and a few species have one inside the other.

On this photo the dry part that the flower stalk is comong out of ia the sheath ( this is a single sheath)

[Jeff214]

Here is a C. lueddemanniana wingged tip. You can see from the side view that the tip has an extrusion that looks like wings.





I don't have a labiata in flower at the moment... but here is C. mossiae. You can see that it does not have the 'wings' on the tip. I don't know if any other catts have this or if all lueddemannianas have this tip (ask a Botanist on that)...but a well known and respected cattleya grower has noted this wing to be a diagonstic sign of C. lueddemanniana.





Here is a double sheath of C. labiata:



Some only have one sheath like C. purpurata:



Or from a single dried up sheath like Guarianthe skinneri:



And some have no sheath at all and the buds appear from atop the psuedobulb without any protective sheath.




And of course, some just do their own thing and flower sheathless, one, or two sheaths...




And here's a photo of C. lueddemanniana alba (top left), C. labaita coerulea (top right), and C. jenmanii tipo (bottom). There is alot of variability among them and sometimes... they honestly look too close to tell apart. C. lueddemanniana seems easier to tell apart .



The best thing would be to contact the seller and see. I've had sellers ghost me when I asked about it but... if they are a reputable seller they should at least answer your questions

Hi Jeff214 and Louis_w,

I am attaching the photo of the overall plant to show the pseudobulb and leaves, column and the dry sheath.

From the dry sheath, i saw is single though and i remember i did use light to shine thru last time and it has only single sheath but im not sure abt the column and lastly the plant pseudo-bulb and leaves looks like lueddemaniana?

I am not sure whether to trust the seller since the 2 photos i attached in this post looks the same and both plants were from him.

Hi Louis_W,

Any advice on the photos?

Dont worry, i am happy that you are willing to check it out for me.

I have attached 2 photos. Please guide me how to identify them.

This is labiata (or a hybrid with labiata) and certainly is not lueddemanniana

By the way, ive reached out to the seller. He confirmed it was cattleya labiata because some experience grower told him he wrongly labelled it. But he was not able to answer me how to differentiate cattleya labiata from cattleya leuddemaniana even after he was told he labelled it wrongly. Please advice, i really want to learn.
