JUSTICIA PROCUMBENS Linn. (Rostellularia procumbens Nees). 
Blanco’s species was reduced by Fernandez-Villar to Justicia 
mollissima Nees, a species not known from the Philippines. The 
form he described is unmistakably referable to Justicia (Rostel- 
lularia) procumbens which is common and widely distributed 
in the Philippines. Blanco’s description typifies Rostellularia 
blancoit Hassk. in Flora 47 (1864) 54.

PLANTAGO MAJOR Linn. 
This was reduced by Fernandez-Villar to Plantago erosa Wall., 
which is a synonym of Plantago major Linn. The species was 
certainly introduced into the Philippines by the Spaniards, 
probably from Spain, and is now very generally known as lantin, 
a slight corruption of its Spanish name llantén. At low alti- 
tudes it is found only in cultivation, being locally used in the 
practice of medicine; at medium altitudes it is occasionally found 
growing spontaneously in and about towns.

throughout the Archipelago at low altitudes in the settled areas.
