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!
That is about right, 8-10cm for most of them. My appletonianum flower is slightly over 10cm but it is a mature plant with 7-8 growths.
I bought a few other species/varieties in this group last few months and the plants look different but I expect the flowers are very similar. I am going to lose my hainanense to root rot, when that happens, I won't buy another one just because its flower is so similar to appletonianum.
