 This genus is kept up hy most authors ; hut I am unahlc, in the ahsence of perfect fruit, 

 to point out any good distinction, except a well-marked one in geographical distrihution, 

 l)ot\vecn it and true Bamhusa. Excepting a douhtful cosmopolitan species, Bamhusa 

 Kulgaris, it may be said that all true Bambusas are confined to the East, and all true 

 CJiiaduas to the "West. The upper palea in Guadua has the keels much more distinctly 

 and l)roadly winged than in any Bamhusa. Ruprecht distinguishes Guadua; as having 

 " Flosculi non exacte distichi ; " but in G. latifolia and many others the flowers are 

 remarkably distichous. Nees, in Agrost. Bras. p. 532, makes Guaduce a section of Bam- 

 hiisn, applying to it the definition of " Spieula3 teretiusculse, stylus 2-3-partitus." This 

 would of course include most of the Indian Bamboos. Rccmer et Schultes define the 

 section Guadua: as having " stylus ])revis tripartitus, floribus inferioribus masculis vel 

 neutris ;" and this, again, would include Bamhusa tulda and many other species of Bam- 

 husa. Kunth, in his 'Notice sur le '^anvc Bamhusa' (1822), separates Guadua from
