Lip three-lobed, saccate, the lateral edges of the midlobe superposed on the lateral lobes of the lip, with an elongate, tongue-like callus on the backwall of the sac.

Care and Culture Card
See basic growing conditions and care information below.
Larger-statured species of Pomatocalpa with erect inflorescences should be grown in pots or baskets with a medium grade epiphyte mixture. Smaller-statured species with pendent inflorescences should be mounted with a small pad of moisture-retaining material at the roots. Provide intermediate to warm temperatures, bright diffuse light, and steady watering throughout the year.
