Paphiopedilum charlesworthii is a species of plant in the family Orchidaceae. It is native to Assam India, Myanmar, Thailand, and southwestern China.
These orchids grew there on high, steep, single peaks, usually on western or northwestern slopes at heights of 1200-1600 m. They were usually found in shade, with roots strongly attached to the rocks, but sometimes they were also found growing in more exposed positions in gaps, naked rocks. This species is a medium sized, up to 25 cm, cool growing epiphyte, that has linear, clear green leaves (20-25 cm long) with purple spots below near the base and on the underside. It blooms in the late summer and fall on a single flowered, pubescent, terminal, erect, to 10" (25 cm) long inflorescence covered with reddish spots and having obovate floral bracts that cover 2/3 of the ovary and carrying a single, long-lasting flower.
