S. Chili; Los Angeles, Coll. Dusén, Jan. 29, 1896 (no. 214). 
Allied to Tr. euphrasioides Bert., a species doubtfully pronounced per- 
ennial by De Candolle, and enumerated among the perennial forms by 
Philippi; but, according to the specimens in the Berlin Herbarium, annual. 
Its leaves, however, are petiolate, and more pinnately parted, and its 
lobes may be 12, as against 2 in our plant. Tr. andinum Phil, very 
similar in habit, is distinguished by the spinose bracts and leaf-segments.
