SELANGOR 1965 (VARIETY) 5C PAPHIOPEDILUM NIVEUM MISSING YELLOW
5c Paphiopedilum Niveum left marginal single missing yellow. Wonderful error. Lightly tropicalised otherwise fine. Mint never hinged. SG138b; SC123var; ISC144g
Note: the error affects the androecium at the centre of the flower and the leaves (causing them to appear blue due to green being made from a mix of blue and yellow inks)
