of tlic Pere Faitje, which bcars thc same iiumbcr as that was sent to H.\.ckei,. 

 As it ajijicared to iiie very mnch the same as the Japanese P. hambusoides, I 

 foUowecl Hackel and adapted tlie same name for the Formosaii plant. But, 

 I did not go to any furthcr examination, uutil I was suggested, by several 

 botanists iu Formosa, of the diffcrence betwecn the Japanese and Formosan. 

 Examining closely, I liave found that they are quite distinguishable even by a 

 single piece of a leaf. In his claborate and nearly exliaustive monograph of the 

 Eambiisacen?, which brings onr knowledge of the family np to date, Camus'' 

 enumerates five species of A-group to which P. bambusoides helongn, viz: — 1, 

 P. hambusoides ; 2, P. j)uberula ; 3, P. Veitchiana ; 4, P. vaontana ; 5, F. 

 puhesccns. Of these sjiecies, om- jilant bcars the closest resembrance to the first 

 species. Tlie uew plant is distinguishable from P. bambusoidcs by the very thia 

 ceraceovts coat covering tlie culms and brauches of a newly grown phmt, l>y the 

 shoi'ter and mucli obtuser bicarinate scalcs at tlie base of the branchlets, by the 

 much broader sliortly ciispidate perules, l)y the much moi-e hirsute mouth of the 

 leaf-vagina, by the longer liirsute ligules and by the leaf-blades, which are iu our 

 plant mncli more cuneate at the base. In P/iyUostachi/s bamhusoides, the 

 newly grown culms are not coated wdth a ceraceous matter, the bicarinate 

 scales are more naiTower and acuter, the perules are naiTower and acute, tlie 

 leaf-vaginm are less liirsute, the ligulcs are much shorter, and above all thc 

 lcaf-blades are more or less rounded at the base, which in tlie uew species are 

 always cuueate at the baso, but never rounded. The two si^ecies are most easily 

 distinguished by the basc of the leaves.
