Aspidium Bolsteri Copel. (Tliis Journal I Suppl. (1906) 252) is 
probably a very large plant of the same species. 
Mindanao, Surigao Bolster 305. The A. Bnjanii reported by Christ 
from Lohers collection on Mount Maquiling, Luzon, is almost certainly 
different. 
Aspidium vastum Bl., a relative of T. Brijanti, with indusiate sori, is 
taken up as a Philippine fern in my Polypodiaeeae of the Philippine 
Islands, but probably by mistake. J. Smith in his enumeration of Cwm-. 
ing's ferns calls T^o. 356 Aspidium alatum Wall., wliicli is synonymous 
with A. vastumjhxit this number is cited by Hooker Sp. Fil. 4: 48, under 
A. pteropus Kze. {=T. decurrens) ; and the material distributed under 
this number included T. grandifolia.

This is a most variable species, if all the plants I am including in it 
are really identical. It was originally stated to have an erect caudex, 
but more recent v.orks have described it as having a horizontal rhizome. 
As a matter of fact, we find this member horizontal, oblique or erect. 
The margin of the frond is entire or variously lobed. Fruiting speci- 
mens with simple and entire fronds occur on Mount Maquiling. Speci- 
mens in our herbaria are : 
Cuming 148, Luzon; Bolster 146, Cagayan (Luzon); Whitford 966, 
Elmer 7999, Mt. Banajao; Merrill 1773, 4042, 5872, McGregor 133, 
Merritt F. B. 6778, Mindoro; Clemens 378, Camp Keithley, Mindanao; 
Copeland 951, 967, Davao; Copeland 1603, Zamboanga.
