no idea... that differentiation always seemed arbitrary to me based on the examples i've seen... so i just enjoy the purpley passion! if it's also extra hairy, that's a nice thing alsoNice flower... mightn't we be in the realm of hirsutissimum var. esquirolei? Or just P. esquirolei?

Since i invested in Guido's newest epistle, it seemed like a good time to go read it...It’s the esquilorei variety of hirsutissinum.
Leslie, sorry to say this, but as far as I can asses this flower by the photo I would more go for P. hirsutissimum. A wide dorsal is a more distinct feature of this than of var. esquirolei. But I won't argue.It’s the esquilorei variety of hirsutissinum.
Nice wide dorsal......
How long must a hair be to be a long hair and how short to be a short hair?.........
"Preduncle and ovary covered with long hairs (hirsute), humps on the staminodal shield distinctly protruding ....P.hirsutissimum"
"Peduncle and ovary covered with very short hairs, humps on the staminodal shield only slightly protruding.... P. esquirolei"
seems like a good taxonomic forum topic... especially since Braem only discusses the hairiness and staminodal shield bumpiness in his most recent book...I once had the two species in bloom at the same time... the different lengths of their respective hirsutissiness (hairyness) were quite distinct. The colour of the infloresence of my "plain" hirs was lighter (more in a greenish direction); the esquirolei (this spelling is from Averyanov, Cribb et al. in their seminal monography on The Slipper Orchids of Vietnam - I guess, they should know) of a very dark colour. But I don't know, if this, too, is a distinguishing trait, or was just by coincidence.
In my experience esquiroleis have overall had the larger flowers, but Rudolf might be right about the size of the dorsal relative to the flower in total for hirsutissimum? Any input from someone with a more specialized knowledge of these varities?
This discussion of the discernability of the plants in question, by the way, I think, for once should make it crystal clear, that it here makes sense to talk of two varities of the same species, not two distinct species in their own right!
