 Tlae stem, distinguished from the rhizome, has its fibro-vascular 

 fascicles frequently separated by medullary plates, the vessels, of 

 various form, being collected into bundles Avithout having the true 

 spirals, (which are rarely wanting) arranged in a special zone 

 around the medulla, excepting in H. lamiyinosa. A distinct 

 fibro-cortical system fails both in the stem and rhizome.

 This wood, used for fishing-floats on the Uaupes, consists of elon-

 usually sparingly dotted, with here and there vertically super- 

 imposed series having their walls covered with miiuite dots.
