Spathoglottis is a genus of orchids (family Orchidaceae). This genus is allied to genera Acanthephippium, Bletia, Calanthe, and Phaius. This genus is abbreviated Spa in trade journals. The genus Paxtonia Lindl. is generally included here.
The common name ground orchid may refer to this genus.
There are both insect-pollinated and self-pollinating species in the genus. They are evergreen plants with crowded pseudobulbs just below the surface of the ground. The 3-lobed labellum projects forward with an extended midlobe which allows insects to land. Both sepals and petals are broad and the sepals are hairy on the outside. The inflorescence arises among sheaths from a recently matured pseudobulb.
They are easy to cultivate and sought after for their large colourful flowers, and are common in tropical gardens. They need sun for part of the day, well-drained loamy soil and regular water.
