This is distinguished from all other species by the width of the leaves far exceeding 

 that of the following species (called latifolia), which is certainly closely allied, but has 

 much longer spicula?. It is one of the numerous plants already referred to at p. 47 as 

 heing called Tagoara or Taquarra by the inhabitants of the country in which it grows. 



In one of Burchell's specimens the leaves are 2\ inches broad, and about a foot long, 

 with 24-28 secondary nerves, and numerous conspicuous transverse veinlets; and on 

 one of the sides of the vaginae near the top there is a curious dense bundle of short hairs, 

 and the cilise are often more than half an inch long. In Wilkes's specimen the leaves 

 are narrower and the cilise have fallen; but there is the same curious alternating bundle 

 of hairs on the vaginse. These two I suppose to be the same as the plant referred to by 

 Ruprecht in a note at p. 131 of his work referred to above, where he says, — " Alia prope 

 Rio de Janeiro provenit species [Guaduce], ramis spicigeris recurvatis G. tagoara? prox- 

 ima, vaginis vero imprimis superne villosis, foliis pedalibus et ultra, 2| poll, latis, spiculis 

 6-9 lin. distincta." I may therefore be wrong in including Burchell's and Wilkes's 

 plants, as I have done, in G. tagoara ; but I have not seen any authentic specimens of that 

 plant. Burchell's second specimen is from the rambling upper portion of the culm ; the 



short branches are pendulous, the ciliae are as long as described above, and the bundle of 



hairs on the vaginse is occasionally present and occasionally absent. There are three 



rather strong recurved spines at each joint of the culm, the internodes of which are 

 scabrous.
