one to which Llanos’s description does not at all apply; moreover 
no species of Deyeuxia is known from the Philippines. The 
habitat given by Llanos is the typical one of Pogonatherum 
paniceum, a species that is common and widely distributed in 
the Philippines, while Llanos’s description applies in all char- 
acters mentioned by him.

ISCHAEMUM Linnaeus 
Andropogon ramosus Blanco FI. Filip. (1837) 37; ed. 2 (1845) 25; ed. 3,

TACHYUM (Cav.) Merr. in Philip. Journ. Sci. 1 (1906) Suppl. 330. 
This species is widely distributed in the settled areas of the 
Philippines, but it is of rather local occurrence although very 
abundant in some regions. Blanco’s Andropogon ramosus was 
reduced by Fernandez-Villar to Ischaemum ciliare Retz., a spe- 
cies that does not occur in the regions from which Blanco secured 
his botanical material. It grows in old rice paddies, low wet 
lands, etc.

ANDROPOGON Linnaeus

The plant Blanco described is certainly a form of Andropogon 
eontortus Linn. The species is very abundant locally in open 
grasslands at low and medium altitudes in the Philippines; it 
is certainly not a native of the Archipelago, but probably was 
introduced after the Spanish occupation.

This species was retained by Fernandez-Villar in the Novis- 
sima Appendix to the third edition of Blanco’s Flora de Filipinas 
as a distinct one. It is very closely allied to Andropogon ziza- 
nioides (Linn.) Urb. (A. muricatus Retz., A. squarrosus L. f.), 
and is apparently identical with Andropogon nigritanus Benth. 
(1849) (A. squarrosus var. nigritanus Hack.), A. muricatus 
var. aristatus Biise, and Andropogon festucoides Presl. It 
differs from Andropogon zizanioides Urb. not only in its slen- 
derly awned perfect spikelets but also in the fact that its roots
