Common Name The Cushion-Like Oncidium

Flower Size to almost 1" [to almost 2.5 cm]

Found in Brazil as a compact, medium sized, hot to warm growing epiphyte with compressed, suborbicular-oblong pseudobulbs carrying a single, apical, rigid, erect, oblong, acute leaf that blooms in the later spring on a slender, erect or arching, flexuous, 5 to 8' [150 to 240 cm] long, loosely paniculate, many flowered inflorescence with linear-triangular, very acute floral bracts.

This orchid does best mounted on treefern and grown in a humid environment with moderately bright light. Watering should be lessened in the winter.

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