Luzon, District of Lepanto, Mount Data (4573 Merrill) November 4, 1905. 
Rather common on dry grassy slopes in thin pine forests at about 2,100 m. 
A species apparently closely related to Spilanthes grundiflora Turcz., differing 
from that species in its much shorter, very dift'erently shaped leaves.
