Well very few times have I seen a mature plant. They are usually over 100 feet tall in a tree or several trees with leaves 1 to 3 feet long. As the plant climbs the leaves become larger and split but once it reaches the top of the tree it starts to produce the small vines again that hang down. These hanging down vines is were most people have reported seeing small flowers they are usually still 30 to 70 feet up in the air. Some theories suggest they bloom only at certain time maybe like bamboo plants. It is hard to say until a flower is examined.
