The inflorescence is a raceme growing Template:Cvt tall and bearing seven to twenty white flowers. The dorsal sepal is concave and elliptic in shape, measuring approximately Template:Cvt by Template:Cvt. The reflexed lateral sepals are lanceolate and measure Template:Cvt by Template:Cvt. The petals are linear and twisted at the base, measuring Template:Cvt by Template:Cvt. The labellum is split into three long, narrow lobes. The nectar spur is Template:Cvt long and slightly curved.[1]
