The plant from Mathews on whi ch the er species is 
based was long ago ragneionied by Bentham (B. & H. Gen. Pl. i 
377 (1873) ) as a Pose species of a In Robinson & 
Greenman’s revision of the genus (Proc. Am. Acad. xxxiy. 529 
pees ib was, bessiehie referred to Viguiera, “evidently through 
sion of numbers or specimens, for the characters 
ssaisbed to it (alternate leaves and sterile ray eat are quite 
at variance with the true character of Mathews 765. This species 
and the next are of tataeast as the first raster of the genus to 
be recorded from Peru; the only other species described from 
outh America are P. lineare (see above) and P. Klattiz Rob. & 
Greenm., both from Columbia
