PIPER BETLE Linn.: Blanco FI. Filip. (1887) 22 (betel); ed. 2 (1845) 16; 
ed. 3, 1 (1877) 30, t. 12. 
The Linnean species was correctly interpreted by Blanco. The 
species is locally cultivated to supply the demand for betle leaf 
for use with the seed of Areca catechu for chewing, the mixture, 
with lime, being locally called buyo. A form of the species is 
common in thickets in some regions, but this wild form is not 
or but little used by the Filipinos. The Tagalog name of the 
betle pepper is icmo or itmo. Piper blancoi Merr. Philip. Journ. 
Sci. 1 (1906) 40 is a synonym.

Piper anisumolens Blanco Fl. Filip. (1837) 23 (sp. nov.) =Piper aniso- 
dorum Blanco op. cit. ed. 2 (1845) 16 (nom. nov.) ; ed. 3, 1 (1877) 31, 
t. 362-=PIPER BETLE Linn. 
Piper anisumolens was reduced by Fernandez-Villar_ to 
Piper marginatum Jacq., without good reason. I can see no 
reason for considering it other than a form of the common 
Piper betle Linn. The form distributed herewith is the plant 
still locally known as buyo de anis, and it agrees with Blanco’s 
description so far as the description goes.
