Cypripedium dickinsonianum is a species of orchid named Dickinson's lady's slipper or Dickinson's cypripedium after American orchidist Stirling Dickinson. It ranges from Southern Chiapas State, Mexico into Guatemala inhabiting open grassy slopes with shallow seeps on south facing hills in Juniper woodlands at elevations of 1,000 to 1,450 meters. It is a small puberulent orchid with only cauline leaves in an upright stem, which are clasping, elliptic to lanceolate, parallel-veined and plicate. The plant begins to bloom at 20 to 25 cm tall and may reach 42 cm. The plant may be colonial, propagating through rhizomes, but is often seen as a single stem.
