1. P. cablin (Blanco) Benth. Cablin, Cadling, Cadlom (Tag.); Patchouli. 
An erect, branched, pubescent herb 0.5 to 1 m high, aromatic when crush- 
ed. Leaves ovate to oblong-ovate, acute or obtuse, 5 to 11 cm long, usually 
coarsely and doubly toothed or crenate. Spikes terminal and axillary, 
panicled, dense, sometimes interrupted, 2 to 8 cm long, 1 to 1.5 cm in diameter

lobes obtuse. Bracts about as long as the calyx. 
Occasionally cultivated for its fragrant leaves, fl. Jan.Feb.; in and 
about towns in Luzon and probably in other islands, cultivated and wild.
