This new species finds its only close relative in W. glauca (see 
beyond), which has much narrower acuminate leaves, more her- 
baceous longer involucre, and acuminate pales, as well as (when 
young) a partly aristiform pappus.

Despite the very satisfactory figures of this plant given by Ortega, 
its identity and systematic position have been more or less in 
doubt. In the Prodromus (v. 549 (1836)) it was placed by De 
Candolle next to Tilesia Mey. (referred to Wulfia by Grisebach, 
Bonpl. vi. 9 (1858)), and was called in the generic description an 
“herba Mexicana,” but in the specific notes, following Ortega’s 
description, was said to come from “ Chili non longe ab oppido 
Chillon.” The plant has never since been collected in Chili, and 
since Hooker & Arnott, in Hooker’s Journ. Bot. iii. 300 (1841), 
Remy, in C. Gay, Fl. Chil. iv. 280 (1849), and Reiche, Fl. Chil. 
tv. 90 (1905), are unanimous in considering its original record from 
Chili erroneous, it seems certain that Née’s specimens came from 
Argentina, particularly since Née, who collected the seed from 
which the species was grown in the Royal Gardens at Madrid, is 
known to have collected along the coast of Argentina as well as in 
Chili. The plant seems common on the pampas of Argentina, 
from Tinogasta (Prov. Catamarca) and Mendoza to Buenos Ayres, 
and is apparently spreading widely if scatteringly to other regions, 
as there are specimens in the Kew Herbarium from waste ground, 
Pensacola, Florida (Curtiss 6492), and from near Melbourne, 
Australia (March 1909, J. R. Tovery). 
Pascalia is maintained as a monotypic genus by Bentham (Gen. 
fig 8 il. 369) on the strength of its “ squamellis in cyathum minime 
coalitis,” its narrow more numerous rays, and somewhat peculiar
