O. REFLEXUM, Lindl. — A pretty species, of dwarf habit and easy culture. 

 Its ovate pseudobulbs are monophyllous, and its leaves narrow lanceolate and 

 acute; the peduncles grow 1^ foot high, and bear short remote flexuous 

 branches, so that the numerous long spikes become covered with abundance of 

 its comparatively large bright yellow flowers, of which the sepals and petals are 

 regularly speckled with brown, and the lip has a few red specks at the base. 

 Reichenbach describes the sepals and petals as dark purple and the lip white, 

 and his uncoloured figure in the Xenia appears to agree with this description. 

 Its flowers' enliven the Orchid house as atitumn is approaching, which should 

 make it a universal favourite. — Mi\tico.

 and the roundish bilobed lip with a stain of the same colour across its base.—
