COLONEL MUNRO'S. MONOGRAPH OF THE BAMBUSACE^. 41 



Ruprecht, in the figure above quoted, g-ivcs very full details of the structui-e of the 

 curious spiculse of this plant. I have already mentioned, at page 20, that Arimdinaria 

 Ti'iaiKB aj)pi'oaches this in some respects, especially in the heterogeneous spiculae.

Culmus " mediocris" (Moritz), glabcr, fistulosus. Spatha fusca, fere glabra, 6 poll, longa, apiculo lanceo- 

 lato fere pedali. Rami floriferi foliiferique ad nodos fasciculati. Folia adulta late lanceolata, 

 striata, 8-9 poU. longa, I2-2 poll, lata (fig. A) ; plurima, praecipue in ramulis brevibus, minora 

 sunt, 1 1-3| poU. longa (fig. B) ; omnia glaberrima, petiolo fusco, glabro vel piloso, subito petiolata 

 sunt. Vagince striatse, apice ciliis validis, basi latis, longissime fimbriatae. Racemus in culmo vel 

 ramulis lateralibus terminalis, spiculis 6-12, sessiHbus, approximatis et rhacheos internodiis multo lon- 

 gioribus. Spicula plusquam 2 poU. longa, 10-14-flora, Isevissima, glumis brevibus, vix acuti ; flosculis 

 1-2 infimis uiiipaleaceis, neutris, reliquis brevioribus (fig. 1) ; rliacliillae ai'ticulis glaben-imis. Palea 

 inferior (floscvili fertUis) 6 liu. longa, dorso glabra, convexa, apice atteuuata, breviter mucronata, 

 utrinque nervis 1-3 notata (figg. 2, 3), saepe purpurasceus ; superior subsequaUs, apice pilis 

 comata, bicarinata et inter carinas pulcherrime ciliatas hirsutiuscula (fig. 4) . Squamula 3, sub- 

 aequales, nervosse, lanceolatae, acuminatse, superne margine fimbriatse (fig. 5). Stamina 3, anthe- 

 rarum loculis apiculatis (figg. 4, 5). Styli 2, basi discreti, stigmatibus 2 longis plumosis (fig. 5). 

 Ovarium (immatujum) lineari-oblongum, infra apicem nigrescentem constrictum. 



One of Moritz's specimens is marked " Nastus Chusquea," H. B. K. ; but that is a very 

 different plant, and is Chusquea scandens, Kth. Moritz states that this plant is called 

 "Cariza" by the inhabitants; but I find that this same name is used for several (six or 

 seven) distinct kinds of Bamboo. This is a strikingly pretty grass, far surpassing the 

 remainder of the genus in appearance.
