of the Pere FAURIE, which bears the same number as that was sent to HACKEL. 

 As it appeared to rne very much the same as the Japanese P. bambusoides, I 

 followed HACKEL and adapted the same name for the Formosan plant. But, 

 I did not go to any further examination, until I was suggested, by several 

 botanists in Formosa, of the difference between the Japanese and Formosan. 

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

 single piece of a leaf. In his elaborate and nearly exhaustive monograph of the 

 Bambusacese, which brings our knowledge of the family up to date, CAMUS* } 

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

 P. bambusoides ; 2, P. puberula ; 3, P. Veitcltiana ; 4, P. montana ; 5, P. 

 pubescens. Of these species, our plant bears the closest resernbrance to the first 

 species. The new plant is distinguishable from P. bambusoides by the very thin 

 ceraceous coat covering the culms and branches of a newly grown plant, by the 

 shorter and much obtuser bicarinate scales at the base of the branchlets, by the 

 much broader shortly cuspidate perules, by the much more hirsute mouth of the 

 leaf-vagina, by the longer hirsute ligules and by the leaf-blades, which are in our 

 plant much more cuneate at the base. In Phyllostacliys bambusoides, the 

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

 scales are more narrower and acuter, the perules are narrower and acute, the 

 leaf-vaginas are less hirsute, the ligules are much shorter, and above all the 

 leaf-blades are more or less rounded at the base, which in the new species are 

 always cuneate at the base, but never rounded. The two species are most easily 

 distinguished by the base of the leaves.
