is indeed Dendrobium farmeri. This colour form has never been formally
described, so your use of the name Dendrobium farmeri var. aurea is
incorrect (plus, it would be "aureum", not "aurea").

The first record of this colour form appears to be in "Beautiful Thai
Orchids" by Kamemoto & Sagarik (Orc. Soc. Thai., 1975). The authors call
this colour form "Dendrobium farmeri var. aureoflava" but, once again,
failed to legitimately publish the name, so it's use (in a formal sense) is
incorrect. Also, the epithet should be spelled "aureoflavum", not
"aureoflava".

Kamemoto & Sagarik published a colour photo of this colour form, and
commented that it has been collected from forest at high elevations in the
Khanburi region of Western Thailand. They stated that it's leaves are
thicker, broader and greener than the normal type, and that it flowers in
May-July instead of Feb-March.
