 latis, vel ssepe solitariis, plurimis cylindricis acutis, angustis, incompletis, vix 9 lin. longis, paucis 

 oblongis, compressis, 12-16 lin. longis, et i lin. latis, bromiformibus. Spicula fertilis 11-13-flora,

 6i liu. longa, cariuis inconspieue fimbriata. Squamiila 3, oblongie, longe fimbriate. Stamina 6, 

 monadelplia, antheris mucrone hirsuto vel penicitto pilorum apiculatis. Stylus longus, hirsutus, 

 superne bifidus. Ovarium (immaturum) apice hirsutissimum, longe rostratum. 



This has a very different appearance; from the two preceding species. The perfect 

 spicuhi has a considerable resemblance to that of Bainbusa viilffarLs. 



Species dubia, folia tantuni.

Those leaves are different from some marked " Apus" in hb. Horsficld, as already 

 mentioned at ]). 113. In many respects they correspond perfectly with Schultes's descrip- 

 tion of B. apus, differing principally in having hirsute petioles. Hasskarl, in Cat. Hort. 

 Bog. 295, says that "Apus" belongs to the genus Dcndrocalamus.
