are odorless; it is probably best, however, to consider it merely 
as a variety of Andropogon zizanioides Urban. Merrill 4231 
and 4240 from Pampanga Province, Luzon, represent Andropo- 
gon anias Llanos, both distributed as A. squarrosus Retz. 
Illustrative specimen from Arayat, Pampanga Province, Luzon, 
November, 1914, comm. J. Santos, there known as anias (Merrill: 
Species Blancoanae No. 389). 
Andropogon nardus Blanco Fl. Filip. (1837) 39; ed. 2 (1845) 27; ed. 3, 
1 (1877) 51, non Linn. =ANDROPOGON ZIZANIOIDES (Linn.) Urban 
(A. squarrosus Linn., A. muricatus Retz.). 
The species is common and widely distributed in the settled 
areas in the Philippines and is frequently planted along the banks 
of rice paddies. It is certainly not a native of the Philippines 
and has possibly been introduced since the Spanish occupation 
of the Archipelago, although it may have been introduced in 
prehistoric times.

October, 1913 (Merrill: Species Blancoanae No. 355). 
Rhaphis trivialis Lour.; Blanco Fl. Filip. (1837) 45=Andropogon acicu- 
laris Roem. & Schultes; Blanco 1. c. ed. 2 (1845) 26; ed. 3, 1 (1877) 
49=ANDROPOGON ACICULATUS Retz. 
This was correctly referred to Rhaphis trivialis Lour., and 
later to Andropogon acicularis R. & S. by Blanco, the former 
being a synonym of the latter. The species is a pest in the 
settled areas of the Philippines on account of its barbed rachillas 
by which the spikelets adhere to ones clothing and to the fur 
of animals. It is very common and widely distributed in the 
Philippines but has no true native names, being known by a 
Spanish name, amores secos, or corruptions of it; this probably 
indicates its introduction into the Philippines after the arrival 
of the Spaniards, for it is certainly not indigenous to the Archi- 
pelago.

Andropogon schoenanthus Blanco Fl. Filip. (1837) 38; ed. 2 (1845) 27> 
ed. 3, 1 (1877) 50, non Linn.=ANDROPOGON CITRATUS DC. 
Fernandez-Villar considered that Blanco correctly interpreted 
the Linnean species, but this is certainly not correct; Andropo- 
gon schoenanthus Linn. does not occur in the Philippines. 
Blanco speaks of his Andropogon schoenanthus as indigenous, 
but this is certainly not the case. It is never found outside of 
cultivation, except perhaps near deserted plantations, and very
