GRAMINEAE Q1 
In thickets bordering low wet lands, fl. Sept.-Dec.; widely distributed 
in the Philippines. Marianne Islands. 
15. THEMEDA Forskal 
Tall, annual or perennial grasses, with usually long leaves. Spikes 
“many, short, crowded in panicled fascicles, the fascicles and spikes with 
-spathe-like leafy sheaths. Spikelets many, the lower ones male or neuter 
awnless, forming a false whorl about the 1 to 3 middle perfect ones which 
are long-awned. Perfect or female spikelets linear-oblong, the first glume 
terete or dorsally compressed or channelled, coriaceous, the second as long, 
. the third hyaline, 1-nerved, the fourth very narrow, awned. Pedicelled 
spikelets with 1 to 3, 1- to many-nerved glumes with often inflexed margins 
and keeled wings. (From its Arabian name thaemed.) 
Species about 10, warm parts of the Old World, 2 or 3 in the Philippines. 
1. T. triandra Forsk. 
Erect, perennial, nearly glabrous, 0.5 to 1.5 m high, the stems rather 
slender, often with short branches and very leafy above. Leaves linear, 
8 to 20 em long, glabrous or slightly hairy. Inflorescence long or short- 
peduncled, paniculate, the spathes longer than the spikes, the outer ones 
up to 5 em in length. Lower whorled spikelets about 1 cm long, the 
perfect one solitary, somewhat shorter. 
In open dry grass lands near La Loma, Fort McKinley, etc., fl. May—Oct.; 
widely distributed in the Philippines. Tropical Africa and Asia through 
Malaya to Australia. 
16. ANDROPOGON Linneaus 
Fine or coarse grasses of various habit. Leaves flat, base rounded or 
cordate. Spikes solitary, in pairs, digitate, or panicled, the rachis usually 
fragile, jointed. Spikelets usually narrow, in pairs, one sessile, female 
or bisexual, the other pedicelled, male or neuter. Sessile spikelets 1- 
flowered, the glumes 4, the first usually keeled, dorsally, rarely laterally 
compressed, the second as long as the first, awned or not, the third hyaline, 
empty, the fourth hyaline, broad or narrow, 2-fid and awned in the cleft 
or reduced to an awn. Pedicelled spikelets various, glumes 3 or 4, the 
fourth awnless. (Greek “man” and “beard” in allusion to the bearded 
inflorescence of some species.) 
Species about 240, tropical, subtropical, and temperate, about 18 in the 
Philippines. A very large and polymorphous genus of many sections or 
subgenera, these by some botanists considered to be of generic rank. 
1. Internodes of the spike deeply cupped at the apex. 
2. Sessile spikelets of the lowest pairs differing from those above them, 
in sex or in form; spikes panicled; a cultivated, coarse, tufted, per- 
ennial grass, the leaves with a lemon-like odor when crushed. 
1. A. citratus 
2. Sessile spikelets all alike; solitary, their peduncles enclosed in a spathe- 
like leaf-sheath; a very slender grass..................2..........--- 2. A. fragilis 
1. Internodes of the spike truncate, not cupped. 
2. Sessile spikelets of the lowest pairs different from the upper ones. 
3. Spikes digitate, densely white-villous........................... 3. A. sericeus 
3. Spikes solitary; spikelets long-awned........................-... 4, A. contortus
