 (immaturum) obconicum, trigonum, styli basi inerassata coronatum, supcrne pubescens. 



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

 that of the following species (called latijhlia), Avhich is certainly closely allied, but has 

 niueii longer spiculae. It is one of the numerous plants already referred to at p. 47 as 

 being 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 2i-28 secondary nerves, and numerous conspicuous transverse veinlets; and on 

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

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

 are nai-rower and the cUise have fallen ; but there is the same curious alternating bundle 

 of hairs on the vaginae. These two I suppose to be the same as the plant refei-red to by 

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

 Rio de Janeiro provenit species \_Cruadu(B\, ramis spicigeris recurvatis G. tagoarcB prox- 

 ima, vaginis vero imprimis supcrne villosis, foliis pedalibus et ultra, 2^ poll, latis, spiculis 

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

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

 plant. liurcheU's second specimen is from the rambling ujjper portion of the culm ; the 

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

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

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

 scabrous.
