The flowers are translucent green; the labellum is green and has brown blotches on its mid-lobe. The dorsal sepal is shaped narrowly lanceolate and has an acute apex. The dorsal sepal measures 4.5mm long and 1.5mm wide. The dorsal sepal has one distinct vein and has an entire margin. The lateral sepals are shaped narrowly lanceolate and have acute apices. The lateral sepals measure 5mm long and 1.5mm wide. The lateral sepals have one distinct vein and have entire margins. The petals are shaped lanceolate and have acute apices. The petals are shaped 4.5mm long and 1.8mm wide. The petals have one distinct vein and have entire margins. The labellum is porrect and 3-lobed. The labellum measures 3mm long and 1.5mm wide.

Other Information

 

Jim Cootes saw this species in a private collection of plants during a recent visit to Mindoro.

 

This species is similar to Dendrochilum unicallosum but differs by the floral segments and the distinct rib that runs on the outer surface of the tepals and the rib that runs along the upper surface of the labellum.

 

The epithet honours Raven Schneider who is an orchid enthusiast on Mindoro. The original plant was found growing in his collection.
