HE genus Lilaea is a peculiar monotypic one, the single 
X species, L . subulata, being widely distributed through 
the western part of the American continent. According 
to Hieronymus 1 , who has made the most careful study 
of the plant, its range is from Oregon, throughout the 
coast region of California and Mexico, into South America. 
In the latter it has been collected in Colombia, Chile, Argen- 
tina, and Uruguay, and has been found at various elevations, 
from sea-level to a height of 3,000 metres. 
There is much diversity of opinion as to the systematic 
position of the plant. In Engler and Prantl’s Natiirliche 
Pflanzenfamilien 2 , it is classed with the Juncaginaceae ; but 
Schumann 3 is inclined to consider it as representing a special 
family, Lilaeaceae, proposed originally by Hieronymus, and
