LEAFLETS OF PHILIPPINE BOTANY [Vor. I, ART. 7 
with elongated prostrate stems either simple or divaricately 
branched and rooting at the nodes. Leaves sessile, linear, 
oblong but quite variable, obtuse or acute, subcrenate, base 
either narrowed or truncate. Heads axillary and terminal, 
sessile or short pedunculate. 
Although we have seen no specimens Villar reports to 
have seen living specimens in stagnant water of Luzon and 
Panay. Since it is native to Sumatra, Malay, China and 
Cochinchina its occurrence in the Philipines seems very possible. 
32. ECLIPTA LINN. 
Hirsute annuals, with opposite leaves. Heads heterog-

tile, tubular, 4 to 5-segmented; involucre broadly campanulate, 
its herbaceous bracts in 2 series; scales enclosing several 
flowers, the inner ones narrow or absent; anther bases sub-

than the linear inner ones, strigose; young achene ciliate at 
the apex, when mature subcompressed, its edges thick and
