Near S. Parishzi, Hook. f.; but the flowers are differently 
- coloured, the lateral lobes of the lip much longer, and the 
septum of the spur much longer, completely separating the 
spur into two halves except at the top and bottom, with a 
thickened portion where it rises from the mid-lobe on which 
the dorsal callus rests. The pedicels of the flowers are much 
longer, and the flowers more distant. The pollinia much 
resemble those of S. Parishit.
