- Species Phreatia sarawaketensis
Phreatia sarawaketensis is superficially similar to P. macra Schltr. (section Caulescentes) but differs in the broader leaves (0.35–0.425 cm versus 0.125–0.175 cm), the flowers which are twice as large (sepals 0.2 cm versus 0.1 cm long) and the flat-bottomed lip (versus semiglobose).
Phreatia sarawaketensis differs from Phreatia keysseri Schltr. also from the Sarawaket Mountains, in having shorter (4.6–6 cm versus 10–12 cm) and narrower leaves (0.35–0.425 cm versus 0.6–0.85 cm), and flowers with an elliptic (versus quadrate), narrower (0.15 cm versus 0.225 cm), at the base glabrous lip lamina (versus pubescent).
