This plant is very local here, I only found it in one stream, and 
in this for only the distance of about a mile when it ceased, 
although if I had searched for it for a longer time I might have 
found it further afield. I searched other streams but did not 
find it, and the Kachin with me told me that it grew nowhere 
else. It only grew in deep shade.
