Is this Dend. schulleri?
 

Someone told me they think theirs looks exactly like mine and that is what he has. Any ideas?

Need a clearer foto. Can't define the lip keels, etc.

It is green
 

Is this better

Patricia,
definitely helps. Are there three ridges on the lip, or 5? Three is D. schulleri, while 5 would be D. mirbelianum. That said, I think it is a hybrid, as the lateral petals are very long for the species, as well as having a half-twist. If a hybrid, then I would say 50% D. schulleri. The other parent could be a hybrid or related species. The hybrid D. Alice Noda (schulleri x discolor) is very similar. D. schulleri is very popular for hybridizing due to the clear yellow to green colour in the better clones. It comes from the north-west island groups of New Guinea and needs warmth and sun.

Ridges?
 

Do you mean the white in the center bottom of lip? There are 3. So, it is not the schulleri? But I will look up the other dend you mentioned. Thank you for helping.
