This species is common and widely distributed in the Philippines 
especially near the seashore. The new combination is necessary according 
to the Vienna Code, as Zoisia Willd. (1801) is included in the list of nomina 
conservanda in preference to Osterdammia Neck. (1791), while Agrostis 
matrella L. supplies the oldest specific name.

This species is only cultivated in Manila and is a native of China or 
Japan. Its synonymy is quite complicated, but what is apparently the 
oldest valid specific name is here adopted. Panicum arhorescens Linn. 
Sp. PI, (1753) 59 may in part be referable here, as "Index Kewensis" ^ves 
this species as in part referable to Arundinaria glaucescens and in part to 
Panicum sparsicomun Nees. I am unable to determine the type of the 
Linnean species, the first reference being to "Fl. Zeyl. 43," and the 
description given by Linnaeus in that work does not appear to me to be 
applicable to Bambusa glaucescens; the second reference is to "Hort. Cliff- 
27," which work is not available here. The reference to "Panicum glau- 
cescens Lam. Encycl. 4 (1798) 749," quoted by many authors and given in 
"Index Kewensis," does not appear in Lamarck's work, and Roemer and 
Schultes appear to have been the first authors to use the name. I am 
informed by the Director of the Royal Gardens at Kew that the original 
manuscript of "Index Kewensis" gives no additional information regarding 
this name, and that it was probably taken up from Roemer & Schultes 
"Syst. Veg.", or from Kunth's "Enumeratio" without checking the reference. 
Panicum arborescens Lam. is published on page 749 of the "Encyclopedie," 
and "Panicum glaucescens" of Roemer and Schultes was probably an error 
in transcribing the name. Panicum arborescens Lam. (non Linn.) is 
undoubtedly the same as Bambusa glaucescens (Willd.) Sieb. The specific 
name "glaucescens** undoubtedly dates from Willdenow as given in the 
synonymy above.
