the plant from Mexico. The species was certainly purposely 
introduced into the Philippines for its fragrant flowers.

Blanco seems to have interpreted the Linnean species correctly. 
His specimens were from Bauang, Batangas Province, Luzon. 
The plant was there known as sapinit, a name rather indiscrimi- 
nately applied to spiny plants such as Rubus, Mezoneurum, 
Caesalpinia, etc. The species was introduced into the Philip- 
pines from Mexico, through the medium of the old Acapulco- 
Manila galleons. It has in recent times been collected but twice 
in the Philippines, a single specimen from Cagayan, Misamis 
Province, Mindanao, and the material distributed herewith 
secured in Bauang, the place of origin of Blanco’s specimens; 
it is still known in Bauang as sapinit. This is a very excellent 
illustration of the persistence of an introduced species, as Blan- 
co’s original observation of the plant in Bauang antedates the 
year 1837.

This species is widely distributed in the Philippines at low and 
medium altitudes in the open country of the settled areas. It was 
purposely introduced on account of its sensitive leaves at about 
the time, or shortly before, Blanco wrote the first edition of
