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.

Cited as a synonym of Oncidium divaricatum but due to visual differences I am going to keep them separate for now.

Synonyms Aurinocidium sphegiferum (Lindl.) Romowicz & Szlach. 2006; Grandiphyllum sphegiferum (Lindl.) Docha Neto 2006
