Stem 3 m tall. Leaves large, 65 cm long or more, 6 to 9 cm wide, 

 oblong, petioled, cuspidate, the lamina sparingly pubescent on the upper 

 surface, thickly pubescent beneath ; petiole 4 cm long, densely pubescent ; 

 ligule short, densely hairy; sheath very sparsely pubescent. Panicle 

 dense and large, over 30 cm long, the rachis thick hairy. Branches 

 short, 2- or 1-flowered, densely hairy. Bract large, oblong, hairy, 3 cm 

 long. Corolla-tube short. Petals oblong, obtuse, the upper one hooded, 

 2 cm long, 5 mm wide, hairy. Lip 4 cm long, 2.5 cm wide, rhomboid
