The leaves are described as oblong oval to lanceolate or spatulate, at the front they end with a short, attached, slightly rounded tip. The length of the leaves is 8 to 15 centimeters, the width 2.5 to 6 centimeters, the petiole is only 1 centimeter short.
The inflorescence is thick and short, it becomes 2.5 to 4 centimeters long and has around 12 flowers . The bracts of the flowers are roughly elongated, ending bluntly, 0.4 to 0.8 inches long. The curved ovary is 4 inches long. The petals are - except for the lip - narrowly lanceolate and 3 to 5 centimeters long. The inner petals are slightly narrower than the outer, slightly concave in shape and keeled on the outside. The lip becomes 5 centimeters long, it is elongated and indistinctly three-lobed. While the side lobes are blunt and rounded, the middle lobe is longer, it ends pointed and is curved far down. There are thread-like appendages on the middle lobe, further towards the base of the lip the appendages are wider. The column will be 3.7 centimeters long. The fruit is not curved and is 10 to 12 centimeters long, it smells aromatic.
