Description
P. appletonianum is a small to medium-sized slipper orchid that grows in humus or leaf litter, and sometimes in mossy trees or boulders. It has 6 to 8 narrowly elliptic to oblong elliptic leaves measuring long and wide, with its upper surface being green with obscure dark green mottling, and its lower surface is keeled with purple marks at the base. The purple, shortly pubescent inflorescence, measuring, consists of a single terminal, erect flower with a width of, having an extremely variable staminode. Peak flowering occurs in March until May.Two natural variants are available, the Hainan variant, P. appletonianum var. hainanense, and an albino form, Paphiopedilum appletonianum fma. album. The Hainan variant has some slightly different features from its Indochina counterpart, including a brightly coloured bloom, and its boldly mottled leaves, with some taxonomists define it as a separate species altogether.
