an error, as Blanco’s description does not apply to that species 
[Berria ammonilla Roxb.].”” I am now of the opinion that F.- 
Villar was correct unless one wishes to segregate the Philippine 
form from the Indo-Malayan one as a distinct species, which is 
hardly practicable. The Philippine form has been described by 
Turczaninow as Hexagonotheca cordata. The species is of very 
local occurrence in Luzon, in Batangas, Union, Zambales, and 
Bataan Provinces, Blanco’s data extending the range to Bulacan. 
The Tagalog name pacpac balang means “locust’s wings,” ap- 
parently selected with reference to the fruit characters; attempts 
to locate the tree under the above native name resulted in the 
bringing in of Gyrocarpus americanus Jacq.

The species Blanco described as new, Corchorus catharticus, 
in the first edition of his Flora de Filipinas, he correctly reduced 
to the Linnean C. olitorius in the second edition. The species 
is widely distributed in the Philippines at low and medium alti- 
tudes in the settled areas. It occurs as a weed in waste places, 
open wet lands, banks or rice paddies, etc., but is not cultivated 
or if cultivated then on a very small scale.

The Linnean species was correctly interpreted by Blanco. It 
is widely distributed in the Philippines at low and medium alti- 
tudes in the settled areas, occurring as a weed in waste places, 
on the banks of rice paddies, etc. It is not cultivated on a com- 
mercial scale in the Archipelago.

This species is common and widely distributed in the settled 
areas of the Philippines at low altitudes; a weed, certainly 
introduced. —
