Very nice!
I love this group but they are in such a mess! Under untrained eyes, the flowers look too similar/same..some of them shouldn't have been rewarded as separate species IMO...the plants/leaves/size may look very different though.
Yours has a very tall spike...how big is the flower?
My appletonianum is still in bloom(6-7 weeks now)...11cm NS. The LS is only 6"...different leaf markings and colors compared to your plant. The flower stem is 5-6" tall. What an intersting group!
