HAB. In partibus mediis Formosa? ubique culta. 



The present plant is one of the most abundantly planted species of the 

 Bambusaceae in the middle part of Formosa. The species was regarded for 

 some time past to be identical with Phylloslacliys bambusoides SIEB. et Zucc. 

 The first botanist who recorded our plant under the same name from Formosa is 

 E. HACKEL. In 1904, in his Suppleinenta Enumerationis Graminum^, this emi- 

 nent authority reported " *P. bambusoides SIEB. et Zucc. in Abh. Acad. Munch. 

 III. p. 745, in montibus prope Kelung, FAURIE 765" with a note "die mit * be- 

 gleichneten Arten und Varietaten sind fur die Flora der betreffenden Lander 

 neu." In 1905, Professor MATSUMURA, referring to HACKEL'S paper, mentioned 

 the occurrence of the species in Formosa in his Index Plantarum Japonicarum 2) . 

 Later on, in 1906, when I was working our Enumeratio Plantarum Formosa - 

 narum s) in conjunction with the said professor, I examined one of the specimens
