Common Name The Wasp-Carrying Oncidium

Flower Size almost 1" [to almost 2.5 cm]

Found in southeastern Brazil as a small sized, hot to cool growing epiphyte at elevations up to 1200 meters that has broadly oval to subglobose, clustered, strongly compressed pseudobulbs carrying a single, apical, rigid, elliptic-oblong, acute, pale green leaf that blooms in the summer and fall on a 4 1/2' [135 cm] long, paniculate inflorescence with many waxy flowers.

O sphegiferum is very similar to and most likely is conspecific with O divaricatum, O robustissimum and O pulvinatum. If so then O divaricatum takes precendence.
