 p. 7. Seeds with broad, membranous edges, crowned. The 

 bark contains a quantity of fibrous matter, which the natives of 

 the country where the plant grows use as a substitute for hemp. 

 Dr. Roxburgh found, by steeping the roots in a fish-pond, 

 in order to accelerate the removal of the bark, and cleansing the 

 fibres, many, if not the whole, of the fish were killed : hence the 

 specific name.
