Mr. Rae has seen this specimen, and also 2746 (1. burmanica, 
Hook. f.), when growing, and states that they are very different in 
appearance. Mr. Grant’s description of colour is ‘‘ Flower yellow 
and claret, spur yellow with brown stripes, outer wings buff, 
turning to yellow at base with stripes of claret and maroon, 
standard yellow and deep claret.’’

flower one wing had the above marking, but not the other. J
