brown ; lip hastate, much smaller, yellow, the side lobes being 

 dark purplish brown. It is perhaps the grandest Onddium 

 \&i introduced ; the cool-house suits it best, and it should be 

 potted in peat and sphagnum moss, with good drainage. It

 spikes of bright yellow flowers, barred with brown, and which
