COLONEL MUNRO'S MONOGRAPH OF THE BAMBUSACE^. 141 



to the genus Cephalostachyiim ; but the specimen is from an immature state of the plant ; 

 and I did not consider myself justified in taking more than one spicuUi for examination. 

 The inflorescence is so thoroughly concealed l)y the ujipernxost leaves, that no casual 

 observer would perceive that the plant was in flower.

 glomerulis spicularum, per intervalla 1-2 poll, distantibus, secus ramos dissitis, flore

Brandis's herbarium contains numerous excellent specimens of this beautiful Bamboo, 

 the branches of which are quite as slender as ordinary packing-thread, and yet bear 

 numerous verticUs, often an inch in diameter, with considerable intervals between them. 

 The fascicles are more compound in this than in any of the other species of the genus, 

 and often as much as in some species of Melocaiina and Schizostachyum. The sterile 

 spiculas are not numerous.
